Fundam for bath

Having decided to build his own hand bath, care should be taken on the construction of high-quality basis. Even if the building size will be modest, ignore the tab base can not be: it is the quality characteristics of the finished buildings will depend on the basic design. Before you get started, you should understand how and what to produce the foundation for a bath 4x6 with your own hands.

Selecting type basic structure

Choosing a foundation for a bath

Soil type is one of the fundamental factors that allow to determine the type of foundation:

  • At stable rocks can be used on the basis of the columnar supports, deepens in the middle and greater depth;
  • On sandy soils can perform a tape base, as it whiter stable and not very sensitive to the movement of the soil;
  • Silty rocks are unstable, so at this plot of land would be appropriate pile type base or slab basis;
  • Argillaceous rock layers almost always occurs on more solid ground, so in such areas should erect a tape or columnar base with a large recessed.

The landscape also determines the choice of the form the base under the bath. In areas with a significant angle of inclination is best to use the type of pile foundation, which allows to reduce costs and increase operational structure lines. If the site are non-essential differences of height, it is best to use a tape substrate.

As for the depth of the, the deepening of the future basic structure depends on the depth of soil freezing. Often laying the foundations below the frost made the ground 200-250 mm (especially if the structure is massive). For light structures (3, 3, 4 by 4 or 4 to 6), it suffices to 80 cm.

First of all, before the mark portion, it is necessary to calculate the diameter of the holes or width of the trench. The dimensions of the trench wall thickness usually exceed 100-200 mm.

Strip foundation for bath

If you are the foundation for a bath 4x6 with their hands, the tape version will be a great solution.

It all starts with the performance of work on digging the pit. A suitable width of the recess for a small construction - 250 mm.

The bottom of the trench should be leveled and pour on it a layer of sand and gravel layer. The minimum thickness of each such layer should be equal to 100 mm. After laying sand and gravel pad moistened with water and compacted.

Performed installation of the formwork, which should exceed the height of the base of the future 100-150 mm. For this purpose a clipping board, wherein the thickness is 30 mm. Planks are secured together by means of screws and the wooden beam.

Reinforcing casing is made of metal rods, whose thickness may be from 12 to 16 mm. Rods used for fastening the binding wire.

At the bottom of the pit pour a need to broken brick (this is necessary in order to form a gap). Air movement is provided by means of ceramic pipe sections 0.6-0.8 cm, which lays at a distance of 2-3 meters from each other.

Further it is possible to produce concrete placement. We must not forget that the work should be completed within one day. Pouring concrete mix layers is performed, the maximum thickness of each of which is equal to 200 mm. Each layer of compacted concrete. To avoid air spaces need to use a vibrator building. Seven days later, when the concrete has set firmly, to dismantle the box. Concrete solution completely solidify a month.

To protect the foundation from the natural conditions necessary waterproofing. The finished base can be covered with roofing felt or bitumen. otmostka constructed for removing excess moisture from the base structure.

Pile-screw base for bath 4 to 6 m

Helical pile foundation for bath

To date, very popular received base on screw piles. Although the cost of screw piles significantly higher, install them much easier. These piles are ideal for almost all types of soil, and they can withstand a substantial load. Pile-screw base set is very simple, although its installation requires the participation of 3-4 developers. Thus it is possible not to use specialized equipment.

Piles are arranged on the corners of the structure, as well as docking points of the walls. Between the bearing piles at a certain distance deepened additional pile support. Distance between supports should not exceed 2 m.

The ideal width of pipes, which are made of screw supports - 200 mm. The required thickness of the pipe wall - 4 mm. By sharp tip screw support attached by welding blade 5 mm thick. Before installation, all pile elements to be treated with a special compound to protect the metal from rusting.

Supports alternately screwed into the soil in pre-prepared holes. First mounted corner, and then the intermediate supports. Initial penetration screw support should be carried out to a depth of 300 mm.

Then it is necessary to increase the depth and screw each pile to support stable rock (1.5 m). During penetration you must make sure that the pile elements are not moved or tilted. After installation of all the supports necessary to bring them to the same height, having cut an unnecessary part of the grinder.

Inside the tube blank, because after the device is filled with cement mix in them. This will allow to increase the strength of the entire structure. When the poured cement, to the top of the tube is welded headroom.

To give added resistance of pile grillage basis carried out the execution. For this purpose the U-shaped metal elements (channels), the corners or wooden beams.

columnar base

Fundam for bath on columns

Steam - structure, which refers to additional yard buildings, so it rarely has a considerable weight. Therefore, when a foundation for a bath 4x6 with their hands, a columnar base is an ideal option, which you can build out of scrap materials.

With the construction of a base used-bearing pillars, which are installed at a depth of soil freezing.

One variation of the columnar base is a structure consisting of supports made of baked bricks. It is worth remembering that the pillars that stand at the corners, have a size of 40 by 40 cm, and the side - 25 to 25 cm.

In order to erect a columnar base produced in advance by marking digging pits, on the bottom of which is filled cushion sand and gravel. The thickness of each layer of sand and gravel must be not more than 100-150 mm. After that, proceed to laying bricks.

Relatively simple construction of the technology is different from the base of asbestos cement pipes. Minimum diameter tubes used should be 200 mm.

In the corner points of the structure future need to dig wells 240 mm and a depth of 1500 mm. The recess should be set cement pipe, inside each casing must be placed on four steel rod. At the end of each leg is concreted. When the pipe is necessary to slightly raise the tab to form a booster cushion is made of concrete at its base.

In order to in the future it has been possible to mount the logs or blocks to basic supports, to each tube prior to filling the threaded stud bumps, its length should be about 50-60 cm.

FOUNDATION FOR BATH 4x6 OWN HANDS: Instructions step by step ...

The size of 4x6 meters is ideal for the construction of private baths in terms of invested money and effort, and is considered a standard. Online cooking projects, drawings and video instructions that can make the foundation for this building with his own hands, often, experts advise to pour ribbon melkozaglublenny type. Technology simple construction, to carry important nuances choosing the correct thickness drainage bags, sizes and control level, the use of high-quality solution, reinforcement structure and compaction rammer of each layer.

The base for bath 4x6 m

Table of contents:

The choice of foundation

The main criteria are the site conditions and the material of the walls, with these data to the bath size 4x6 m is selected from the following types:

1. Belt - universal version, demanded the owners of private houses. Technology is appreciated for its construction, reliability, efficiency and simplicity, the foundation is an integral strip of reinforced concrete with a laying depth of 40 cm.

2. Tselnozalivnoy or slab, which is the formation of a solution poured over the drain pads. rarely due to high costs, with the exception of 4h6m construction with supporting constructions made of heavy wall blocks selected for baths.

3. The columnar, with laying of the supports with depth below the frost on the perimeter and corners. Such a foundation is advised to fill in the construction of single-storey log baths from 4x6 or other light materials, for two-storey stone and it is not suitable.

Columnar base for bath

4. Pile and pile-rostverkovy, due to the high cost and the need for involvement of specialized equipment selected rare exception is made in the construction on the uneven or loose sections, high-rise groundwater. The minimum depth of piles of 2.5 m, to make such a foundation can not on its own, requires a minimum of 3 people.

As a result, the owner of the future saunas stops on columnar or tape basis, the optimum in terms of cost and sub forces. The work begins with the preparation of the drawing with the expected type of windows, the location of doors, drovnitsy, internal bearing walls and sewers, to mate with the other buildings: a swimming pool, a veranda. Calculated for bath basement area: perimeter dimensions are known (4x6 m), the width is found by dividing all anticipated loadings (weight structures, wind, snow) on the bearing capacity of the soil (reference value). Placing agreed with the owners of neighboring parcels, the statutory minimum between baths and buildings of 8 m, it is not always possible.

The foundation slab type

Stepwise filling technology on the example of the strip foundation

Recommended Action scheme comprises the following steps:

1. Clearing the construction site.

2. Partitioning future foundation under the bath: starting from the inner corner of the perimeter of 4 × 6, marked check bearing walls and diagonal (the tolerance is 20 mm). Used to refer to the stakes at least 70 cm long and a rope around the edges provides a margin of about 10 cm. At this stage it is important to check the evenness corners and absence of distortions on the diagonal, all dimensions are measured several times.

3. Digging trenches for strip foundations: depth comprises a height bands, and the drain pad 10 cm margin on crumbling the soil, the width - 15 cm higher than the calculated one. Dug deep into the earth poured future bath.

4. Filling gravel-sand pads - at least 10 cm per layer with careful rammer. On heaving soils sand thickness increases to 50 cm, is taken into consideration in the previous step.

Melkozaglublenny foundation

5. Installation of the formwork, used for this purpose downed wooden boards thickness of 3 cm without major cracks. Along the perimeter are updated and re-check the base layout, the corners hard drive in stakes or rods. The height of the formwork structures depends on the size of tape, above the ground, they are raised 10-15 cm. At this stage lay ventilation and drainage holes (if necessary). To eliminate the skew between the boards is fixed blocks of wood of the same length.

6. Filling of broken bricks on the bottom.

7. The assembly and installation of the reinforcement cage. For foundation suitable under the bath metal rods with a diameter of 12 to 16 mm, connectable via wire or plastic collars. Outside frame to make easier further it is placed so that the metal does not touch the edges of the future tape (recommended indentation is at least 5 cm).

8. Preparation and distribution of concrete inside the formwork. Tape foundation under the bath can be filled with concrete or prepared to do it yourself. Recommended proportions for independent kneading: 1: 3: 3.5: 0.5 (cement: sand: gravel: water). Reviews of allowable strength diverge, the statutory minimum for ready-mixed concrete - M150, but practice shows that it is better to choose a higher mark. The solution was poured in 20 cm layers, each of them slightly compacted (a solid stick, a hammer drill or sputtered air bubbles) and then proceed without interruption to the next, the upper carefully leveled.

9. Removal of formwork after 1 week. Aging concrete (3-4 weeks).

Driving belt structure

A similar scheme can pour the foundation for a bath with his hands when choosing a columnar type. In this case, I have 3 point step by step directions instead of deepening the trench dug for laying square feet. Recommended resolution at the corners of the column is 40x40 cm, lateral - 25x25, the depth of the selected accounting level ground water and 15 cm gravel layer. Supports of erecting w / w, baked brick, stone, asbestos cement pipes concreted diameter of 20 mm.

recommendations

To reduce the risk of skewing baths and lifting strip foundation on heaving soils to be made more thick sand bed: 50 cm, compared with conventional 20. The base under standard conditions and are not insulated waterproofing operate most simple: coated with a bituminous mastic concrete the upper side of the array. In areas with risk reheating recommend pour the solution over polystyrene plates and insulate (isolate or at least moisture) vertical walls.

Many consider the insulation of the foundation for a bath redundant, but its use reduces fuel consumption by heating the premises, maintains a stable temperature and increases the life of the structure. Protection from the inside - a mandatory step is carried out simultaneously with the insulation of floors.

common errors

The main danger is the choice of the wrong type of substrate or insufficient depth of laying. Bath - lightweight construction, even on saturated and heaving soils of many problems can be avoided increasing the thickness of the filling sand cushion. In case of doubt in their abilities in evaluating the soil or the calculation parameters of the foundation is better to turn to specialists. There is also a flagrant violation of casting technologies include:

  • The welding of the reinforcing bars to each other, only the best compound is the tying wire or clamps.
  • The use of concrete with a strength below the mark M150.
  • Preparation and pouring the solution in the cold season or process interruption. On a standard tape base 4x6 m without bearing walls takes a little more than 5 m3 of concrete, it is important to carry out this step in one day.
  • Wintering unloaded foundation. Without conservation, insulation and erection of load-bearing walls it will take only a pile and columnar foundations, strip and slab are deformed under the influence of frost heaving of the soil.

Videotutorial with a photo of the foundation for a bath 4 x 6 with his hands

Qualitative foundation - a pledge of "longevity" of any construction. Therefore experienced masters insist that this process took place in compliance with all technologies. To apply the tape construction of the bath, a columnar or tile type base. In this article we will look at the most successful variant of the foundation for the construction of the size of 4 x 6 meters.

If you want to build a bath with his hands, the first thing you should think about choosing a suitable location for construction. Firstly, it should be quite away from other buildings. The best option would be 3 m separation from home and other outbuildings. Secondly, it is necessary to perform geodetic research and determine the type of soil. According to the results, it is necessary to choose the right kind of foundation:

  • heaving soils. In this embodiment, for better use of the construction bath tape base view;
  • the soil with gravel, sand and clay. Columnar, and tape-and-pillar foundation will be the best choice;
  • primer with quartz and sand. If the soil is dense enough, you can use any type of ground.

After the issue of a suitable base view is resolved, proceed to the realization of the finished project. The whole process will consist of the following stages:

  • cleaning and marking territory;
  • excavation (excavation device trenches);
  • formwork assembly;
  • preparation of the reinforcement cage;
  • direct filling solution.

A more detailed discussion of each of the steps will allow you to carry out laying of foundation with his own hands or to assess the quality of the work carried out under the key, experienced professionals.

During the construction of baths special attention is paid to the base. On the evenness of his casting and strength will depend on the period of service facilities. Therefore, at each stage of the work it is very important to strictly follow the instructions and do not break the technology:

  • clean the area of ​​debris, and dispose of all the irregularities (hollows, hills);
  • marking produce from the inner corner. From him stretched centerlines;
  • such a procedure should make for the remaining corners. Correctness checking markup stretch cord between opposite corners (diagonally). If the difference is 2 cm or more, will have to make adjustments in the layout;
  • then commit markup internal circuits bath, then it can be made for performing the next stage of operation.

Whichever you choose the foundation for its baths, the first step is to excavate their own hands by digging the foundation pit, trenches and wells under the girders. Thus, the essence of the process is as follows:

  • dig a trench width of 30 cm and a depth of 1.5-2 m along the perimeter;
  • then side length of 4 m make appropriate marks for digging holes for bearing piles;
  • it will be enough to install three piles: two on the corners and one in the middle;
  • well depth should be approximately 1.3-1.5 m;
  • on the long side (6 m) counting of a borehole made every 1.5 m;
  • ultimately 12 wells will perimeter;
  • at the bottom of the trench is necessary to lay a bed of gravel and sand.

Making the construction of their own hands, will certainly make sure to it that the trench inner walls were strictly vertical. Flatness can be checked with a spirit level.

An important step towards the creation of high-quality and reliable base is the installation of the formwork. To the foundation has been filled correctly, you should pay attention to the following points:

  • First you need to put together panels of the boards so that they went to the full depth of the trench, and towered above the ground at 30 cm;
  • along the perimeter drive in stakes to the design was strong enough;
  • internal boards surface must be flat, so only use well dried and flat panels;
  • between the boards, located on either side of the trench, it is necessary to make a spacer made of wooden beams.

When installing formwork with their hands need to ensure that between the boards did not have big gaps, otherwise the solution will leak.

After the formwork for the foundation is ready, the next step is to put the valve. With the construction as reinforcement bath can use metal rods with a diameter of 10-12 mm. This is enough to design a robust and durable. The process of stacking must take place as follows:

  1. The rods are interconnected by a metal wire pieces 4 so as to form a square design.
  2. The trench fabricated metal structure stacked horizontally, and in the well under the pile - vertically.
  3. Corner fittings desirable or cut using grinder or the bend angle.
  4. Bars should not rise above the casting surface, so the framework must not be higher than the formwork.

To the foundation for a bath last a long time, you need to make before installing valves additional waterproofing. For this purpose the bottom of the formwork is laid sufficiently dense polyethylene which prevents oxidation of the metal rods.

To pour the foundation with their own hands, should be chosen to be sufficiently warm and dry day, so that the solution froze faster. In the casting process must take into account such things:

  • for solution take cement grade 200 or higher;
  • then evenly mix inside the formwork;
  • after pouring necessarily "puncture" solution wooden stick to eliminate the possibility of the formation of bubbles inside;
  • at the final stage topsheet mixture must properly leveled;
  • in the end it is desirable to cover the foundation filled with plastic wrap.

When filling a base for bath can be purchased already inexpensive ready grout. This embodiment is preferable because special equipment immediately using the "sleeves" flood solution in the formwork, and the process takes a minimum of time.

The construction of a bath - a difficult and responsible action that requires specific skills. And to the whole structure gained a strong and durable, special attention should be paid to pouring the base. If you decide to make laying their hands, certainly familiar with all the intricacies of the process. Only then erected structure will stand for a long time and will not give warps.

Qualitative foundation - a pledge of "longevity" of any construction. Therefore experienced masters insist that this process took place in compliance with all

The foundation for a bath 3x4, 4x4, 3x5 or 4x6 with their hands

None suburban area not without baths. Some owners of land plots put in the bath first, and only then begin to develop land and build a house. For the construction of hire construction crew, but it is expensive, and so some decide to build a sauna yourself.

The first step in building a foundation laying. This step is very important and you need to spend it carefully. How to build a foundation for yourself, what kind of facilities to choose, look at in this article.

Before you begin equipping the base under the bath, you need to be aware of the types of foundations, and choose the one most suitable for your plant. Basic types of substrates:

  • strip foundation;
  • pier foundation;
  • foundation slab;
  • the foundation of the tire;
  • prefabricated monolithic foundation block.

There are some factors that determine the choice of a base. It is important to consider not only the type of soil on the site, but also the specific gravity of the most structures, and since we are building a small bath, then its share is not extraordinary.

Pier foundation will work in the event that construction of the wall will be made of lumber, log out of foam blocks. Just fit the foundation for framing baths. If you plan to build a wall of brick, aerated concrete, you should only install the belt foundation, regardless of soil type.

The base under the bath, made of columns does not require large amounts of material and financial investment. This is one of the economical options. For this reason the type used was the following materials:

  • timber;
  • brick;
  • foundation blocks of concrete;
  • asbestos cement pipes, which are filled with a concrete mixture;
  • concrete.

How do pier foundation - instruction

  1. pillars are set at the corners of buildings, at the intersection of walls and under all walls, both internal and external at a distance of not more than 1 meter apart. It is easy to calculate that under the bath 3x4 will need to install columns 8-12;
  2. pit depth should be equal to 70 centimeters, but it can be more, if the soil in the area of ​​bulk and heaving. At the bottom of the hole you need to fill and compact the sand. Cover the sand with roofing material for waterproofing and install a fully insulated pole, which should rise above the surface of the earth 40 centimeters.
  3. Once the poles are installed obustroitzabirku need - is the wall between the pillars that will protect the cellar against negative environmental influences. To do this, you can use bricks or concrete blocks.

How to correctly set the strip foundation

It is also quite a popular base not only for small baths, but also for other types of buildings. Before you begin to equip the base, it is necessary to pave the way to the construction site. It begins with the markup site.

For markup will need pegs and rope, the length of which is equal to Lina walls bath. At the corners of the pegs are driven and tensioned rope therebetween, at approximately a right angle.

For right angle diagonal is necessary to pull the rope, the length of which must be exactly five meters.

If the site is enough solid ground, the depth of the trench to dig the foundation may amount to only 40 cm., But if the soil heaving and dry, then dig a trench depth of 70 cm. At the bottom of the trench settling sand bags, which necessarily good ram.

Formwork boards are taken, if possible, it is better to use the old timber, because after pouring it will become worthless. If no old material, you have to buy the right amount of boards.

Formwork is being built in one go, all at once, and then pour the concrete need to do the same. The height of the formwork is calculated based on the depth of the excavated trench, e.g. at shallow burial, enough 80 centimeters, otherwise meter. The width of the formwork must byto not less than 20 centimeters.

Reinforcement

The approximate amount of reinforcement for binding base 4 meters per meter of foundation. By means of binding wire reinforcement creates a square and laid into the trench. Will only pour concrete.

What you need to know when casting:

  • solution should fill all at once;
  • as soon as the filling is completed concrete, compacted and leveled;
  • drying time, nearly a month;
  • work is underway to complete drying.

Video tape base arrangement:

very informative video, it can be seen that for the safety of the timber and for better removal of the formwork subsequently, timber covered with plastic to make plenkoy.Kak base yourself.

It is understood that it is necessary to choose the tires are the same thickness and diameter, then the work will be very easy for this type of foundation. On the site is necessary to deliver the required number of tires for arranging the foundation under the bath.

What are the advantages of this material:

  1. Tires are made of special rubber, resistant to all sorts of influences;
  2. material property allows build sturdy and durable foundation for the construction of the bath.
  3. Particular attention should be paid to the insulating qualities of the tires, they carry a moist environment and reliably protect the base of the bath.

As for the disadvantages, it is one - by heating the tire emit harmful vapors to the environment. But properly built foundation of the tire will not be exposed to the sun, from which the tire is destroyed.

Tip: Taking the decision to build the foundation of the tire, it is necessary to evaluate all the advantages and disadvantages of such facilities.

earthworks

  • Dig a trench, the size of which is greater than the area of ​​the structure 20 centimeters on each side.
  • The depth of the pit is 20 centimeters, regardless of the thickness of the tire.
  • The bottom of the pit is filled with sand and well tamped to obtain a flat surface.
  • Then distributed on the bottom of the pit tires, setting them as closely as possible to each other.
  • The next step is to fall asleep in the entire space between the tires and the material for filling should be well compacted, since it affects the base resistance.

Concrete works

  • Before the start of the concrete work, waterproofing set of a film or roofing material.
  • Formwork is created from old boards or plywood sheets.
  • Formwork necessary to construct such a way that the output on the location of the base there was a flat concrete slab.
  • Further, reinforcement is made using reinforcement and binding wire.
  • To facilitate the work, you can use ready-made plates, which are installed on the prepared tire.
  • Pour the solution you need in one go. If you are awake, to cook it yourself, do not forget to add a plasticizer, or a concrete slab can crack when dry.
  • Formwork is removed after a week.
  • Dry foundation in a month.

Consider the value of the work material and the regeneration of the belt, weakly deepened foundation in the table:

Calculation of material consumption and the cost of the pier foundation in the table below:

The table shows the approximate cost of materials and work, as the final price will depend on the type of soil.

Often in violation of everything bath foundation technology over time the foundation begins to break down. What should I do to completely disassemble the construction or repair the foundation?

Repair of the foundation in the home is possible, you only need to know the sequence of the work in each case.

Repair strip footing

In order to produce high-quality repairs, it is necessary to raise the bath log cabin on the grounds. Usually this is done by using a freight jacks, ideally there should be no less than 8 pieces: 4 is placed at the corners and one in the middle of each wall.

Then you need some help, because it is desirable to raise the angle jacks simultaneously.

Once the frame is raised to the desired length, it is necessary to assess the scale of the destruction of the base. If the foundation is cracked and crumbled a little bit, it can be reinforced with a binding wire and reinforcement around the perimeter, set the formwork and pour concrete. The foundation got a little thicker than the previous one, and thanks to the reinforcement and pouring will be strengthened.

If the fracture is considerably skewed one or more angles, you'll need to remove it completely, down to the sand cushion. Sometimes heaving soils at low burial base may break at the time of freezing ground. If this is the case, it is necessary to increase the depth of the trench. Once the trench is dug to the required depth, shading produced new ground. Once it dries, the frame is lowered slowly, do not forget to lay the insulation.

Pier foundation - repair

In this form, the base may meet skewed columns. To resolve this problem, you need to:

  • put the backup next to the twisted column;
  • then removed the old post, deeper hole if necessary. Then you need to build a new harness and install it in the hole;
  • Filling occurs first phase, the solution fills the well to the soil surface;
  • constructed formwork and completely filled column.

In order to strengthen the foundation can be made around the perimeter of the concrete carcass band, which connects the pillars into a single unit that will prevent their further skewed.

As you can see, nothing complicated in arrangement of the base under the bath with his hands. The main thing to understand some things and know the nuances of the fill different types of foundations.

bath foundation arrangement Technology sized 4x6 m

The size of 4x6 meters is ideal for the construction of private baths in terms of invested money and effort, and is considered a standard. Online cooking projects, drawings and video instructions that can make the foundation for this building with his own hands, often, experts advise to pour ribbon melkozaglublenny type. Technology simple construction, to carry important nuances choosing the correct thickness drainage bags, sizes and control level, the use of high-quality solution, reinforcement structure and compaction rammer of each layer.

The main criteria are the site conditions and the material of the walls, with these data to the bath size 4x6 m is selected from the following types:

1. Belt - universal version, demanded the owners of private houses. Technology is appreciated for its construction, reliability, efficiency and simplicity, the foundation is an integral strip of reinforced concrete with a laying depth of 40 cm.

2. Tselnozalivnoy or slab, which is the formation of a solution poured over the drain pads. rarely due to high costs, with the exception of 4h6m construction with supporting constructions made of heavy wall blocks selected for baths.

3. The columnar, with laying of the supports with depth below the frost on the perimeter and corners. Such a foundation is advised to fill in the construction of single-storey log baths from 4x6 or other light materials, for two-storey stone and it is not suitable.

4. Pile and pile-rostverkovy, due to the high cost and the need for involvement of specialized equipment selected rare exception is made in the construction on the uneven or loose sections, high-rise groundwater. The minimum depth of piles of 2.5 m, to make such a foundation can not on its own, requires a minimum of 3 people.

As a result, the owner of the future saunas stops on columnar or tape basis, the optimum in terms of cost and sub forces. The work begins with the preparation of the drawing with the expected type of windows, the location of doors, drovnitsy, internal bearing walls and sewers, to mate with the other buildings: a swimming pool, a veranda. Calculated for bath basement area: perimeter dimensions are known (4x6 m), the width is found by dividing all anticipated loadings (weight structures, wind, snow) on the bearing capacity of the soil (reference value). Placing agreed with the owners of neighboring parcels, the statutory minimum between baths and buildings of 8 m, it is not always possible.

Stepwise filling technology on the example of the strip foundation

Recommended Action scheme comprises the following steps:

1. Clearing the construction site.

2. Partitioning future foundation under the bath: starting from the inner corner of the perimeter of 4 × 6, marked check bearing walls and diagonal (the tolerance is 20 mm). Used to refer to the stakes at least 70 cm long and a rope around the edges provides a margin of about 10 cm. At this stage it is important to check the evenness corners and absence of distortions on the diagonal, all dimensions are measured several times.

3. Digging trenches for strip foundations: depth comprises a height bands, and the drain pad 10 cm margin on crumbling the soil, the width - 15 cm higher than the calculated one. Dug deep into the earth poured future bath.

4. Filling gravel-sand pads - at least 10 cm per layer with careful rammer. On heaving soils sand thickness increases to 50 cm, is taken into consideration in the previous step.

5. Installation of the formwork, used for this purpose downed wooden boards thickness of 3 cm without major cracks. Along the perimeter are updated and re-check the base layout, the corners hard drive in stakes or rods. The height of the formwork structures depends on the size of tape, above the ground, they are raised 10-15 cm. At this stage lay ventilation and drainage holes (if necessary). To eliminate the skew between the boards is fixed blocks of wood of the same length.

6. Filling of broken bricks on the bottom.

7. The assembly and installation of the reinforcement cage. For foundation suitable under the bath metal rods with a diameter of 12 to 16 mm, connectable via wire or plastic collars. Outside frame to make easier further it is placed so that the metal does not touch the edges of the future tape (recommended indentation is at least 5 cm).

8. Preparation and distribution of concrete inside the formwork. Tape foundation under the bath can be filled with concrete or prepared to do it yourself. Recommended proportions for independent kneading: 1: 3: 3.5: 0.5 (cement: sand: gravel: water). Reviews of allowable strength diverge, the statutory minimum for ready-mixed concrete - M150, but practice shows that it is better to choose a higher mark. The solution was poured in 20 cm layers, each of them slightly compacted (a solid stick, a hammer drill or sputtered air bubbles) and then proceed without interruption to the next, the upper carefully leveled.

9. Removal of formwork after 1 week. Aging concrete (3-4 weeks).

A similar scheme can pour the foundation for a bath with his hands when choosing a columnar type. In this case, I have 3 point step by step directions instead of deepening the trench dug for laying square feet. Recommended resolution at the corners of the column is 40x40 cm, lateral - 25x25, the depth of the selected accounting level ground water and 15 cm gravel layer. Supports of erecting w / w, baked brick, stone, asbestos cement pipes concreted diameter of 20 mm.

To reduce the risk of skewing baths and lifting strip foundation on heaving soils to be made more thick sand bed: 50 cm, compared with conventional 20. The base under standard conditions and are not insulated waterproofing operate most simple: coated with a bituminous mastic concrete the upper side of the array. In areas with risk reheating recommend pour the solution over polystyrene plates and insulate (isolate or at least moisture) vertical walls.

Many consider the insulation of the foundation for a bath redundant, but its use reduces fuel consumption by heating the premises, maintains a stable temperature and increases the life of the structure. Protection from the inside - a mandatory step is carried out simultaneously with the insulation of floors.

The main danger is the choice of the wrong type of substrate or insufficient depth of laying. Bath - lightweight construction, even on saturated and heaving soils of many problems can be avoided increasing the thickness of the filling sand cushion. In case of doubt in their abilities in evaluating the soil or the calculation parameters of the foundation is better to turn to specialists. There is also a flagrant violation of casting technologies include:

  • The welding of the reinforcing bars to each other, only the best compound is the tying wire or clamps.
  • The use of concrete with a strength below the mark M150.
  • Preparation and pouring the solution in the cold season or process interruption. On a standard tape base 4x6 m without bearing walls takes a little more than 5 m3 of concrete, it is important to carry out this step in one day.
  • Wintering unloaded foundation. Without conservation, insulation and erection of load-bearing walls it will take only a pile and columnar foundations, strip and slab are deformed under the influence of frost heaving of the soil.

We are building a base for bath sized 4x6 m

Strong base - half of a reliable construction. Because of this, the foundation is given high priority, not only in the manner of work, but also the most important. During the construction of baths, this question is particularly relevant, as will withstand a considerable load. Functionality and size determine the shape of the future construction of the cap.

The construction of the base of their own hands will not be a Herculean effort, if properly consider a number of characteristics of the ground:

Based on these indicators, selected digestible foundation under the bath. There are several options:

1. Belt - the most common and erected their own. It received its name due to the similarity with a ribbon that runs along the walls of buildings. Suitable for almost any type of soil. The technology of its construction is not very complicated. Typically used for constructions simple configuration, no more than two floors.

2. The columnar - represents a number of poles buried under construction corners and interior walls in place of the compounds. The pillars are arranged at the same depending on the anticipated load, but not more than 2 m between them. Suitable such foundation under the bath of lightweight materials, such as frame or a wooden frame. The load on the base should not exceed 1 m 1 m 3. Ideal for soil with deep groundwater.

3. Tea - in the construction of the bath is rarely used. on its execution instruction includes pouring a concrete slab with reinforcement throughout the area of ​​a minimum thickness of 0.5 m. Such a base is suitable for building floors 2-3, complicated configuration on any ground form. Is particularly high prices, due to the high consumption of materials.

4. Pile foundations - is rarely used for baths because of its cost and make it will not be possible without the involvement of specialized equipment to the process of casting. The most modern version of digestible - screw piles. But it will not be able to perform. Piles are screwed into the ground, thanks to the screw tip, forces 2-3 people. Such a foundation is perfect in high groundwater, loose soil or uneven terrain.

Some experts distinguish separate pile-screw type with a raft made of metal piles with strapping wooden beam or I-beam, which gives additional strength to the chassis.

For example, consider two of the most suitable type of base - columnar and ribbon.

As with any construction scheme, the process begins with site preparation and road marking. Needless to say, the size and configuration of the future building should be worked out in advance on the paper drawing. For example we can take a standard bath dimensions 4x6 m.

Originally produced cleaning of the proposed area of ​​debris, vegetation and turf. In order to properly make use roulette layout, squares, supporting stakes and rope.

Note: the site for the bath perimeter from a frame 4x6 m is increased by at least 10 cm from each side, depending on the type of the selected base.

Partitioning starts from the inner corner. The pegs are driven into the ground at the corners to form a rectangle of 4x6 m + 10 cm. Between the legs tensioned rope aligned gon. In order to check the accuracy of marking, laid diagonal ropes. Their length shall not differ from each other by more than 2 cm.

For the construction of strip foundation:

1. digging a trench along the intended circuit with parameters 4x6 m depth, depending on local climatic conditions. The width of the trench is defined as follows: base width 25 cm + 10-15 cm for convenience formwork installation.

2. The bottom of the hole is aligned horizontally, is sprinkled with gravel and sand layers of 10 cm each, moistened with water and thoroughly compacted. On the perimeter are driven metal rods or solid pins, of 3 cm thickness plank formwork going tightly fitted together. To connect using the bars, nails or special ties. The height of the formwork must be above the intended foundation 10-15 cm.

3. prepared formwork Inside stacked reinforcing section 12-16 mm in diameter. The rods are interconnected steel wires. For the formation of gaps between the frame and the bottom of the hole is enclosed broken brick.

4. To provide ventilation can laying ceramic tube diameter 6-8 cm at a distance of 2-3 meters from each other.

5. Pour the base must be continuously recommended to handle for one day. Concrete mortar is poured in layers of 15-20 cm, followed rammer. To remove air bubbles should be used with a simple vibrating hammer or a drill.

6. Formwork allowed to shoot a week after setting solution. complete drying process takes 3-4 weeks, after which you can continue the construction work.

The technology of construction pier foundation includes:

1. Digging holes for pillars in identified locations on the drawing at a distance of 2 meters. For log 4x6 required to fill the order of 16-20 supports depending on the complexity of the bath configuration.

2. The filling each trench with sand 30 cm.

3. Pouring concrete pad 15 cm thick.

4. Adjustment of asbestos pipes vertically on the level. pole placement technique provides the additional use of different materials - brick, metal pipes, concrete, wood - depending on the static load.

5. Reinforcement of poles with iron rods. Sprinkle the outside and sealed with fine sand.

6. Concreting pipes - pour the solution should be to the top and carefully compacted.

7. Concrete Curing takes place much faster. These piles are ready to load in a couple of days.

It is also important to correctly calculate the depth of the basement location, in order to avoid distortions of construction, cracks and other negative influences. The clay, black soil, silty soils size is increased by 20 cm below the frost line. In other cases it may approach or unburied melkozaglublennoe base. For baths 4x6 m in the first embodiment will be penetration of 40-50 cm, in the second - 50-70 cm deep.

Ideal for the foundation will be dry, sufficiently dense homogeneous soil. Worst case - the soil of silt, peat, or fine sand. If the building is still to be on a similar soil, additionally at least 50 cm at the site of the installation base must be done to a depth of a sand cushion.

During the foundation reinforcement rods to bond many use welding. This connection reinforcement forbidden - is fraught with deformation of the base. Pour the foundation with his own hands is quite difficult and costly. Therefore, it is advisable to entrust the process of building the organization. Otherwise the quality can suffer foundation under the bath due to failure of solution preparation instructions.

To make their own solid concrete mix need M250 brand cement above, building sand, gravel and pure water in proportions of 1: 3: 3.5: 0.5.

Creating a foundation under the bath alone 4x6

Selection of the size bath

Buildings require durable and dense base, which will not only serve the sole, but also to distribute the load evenly on the soil. And this applies to both houses and baths, garage, shed, and the fencing section.

Under a small building (4x4 m or 3x3 m) create the foundation is quite simple, and with his own hands. The main thing - do not hurry, carefully perform each of the construction operations and have a desire to build a house with his own hands.

Of course, for a large company should create a vast building with 6x6 or more parameters, which are a few rooms. For such baths foundation should be thorough. It is desirable to choose one-piece monolithic structure or tape form.

If the planned construction of one floor, medium-sized 5x4 or 4x4, it is quite suitable belt type base or foundation on piles with a steel duct. Then the load of the building will be distributed evenly to the ground, and the construction will last for many years without any repairs.

To use the bath in private is not necessary to build a big building (two floors with an internal area of ​​6x6 m), spending on construction of major facilities. It is appropriate to come to take a steam bath in a small 3x3 or 4x4 m, where there are only two rooms. For such a bath is not necessary to build expensive foundations. Suffice it to mark the total area under the support of the foundations of columnar type.

The cheapest option is to choose a bath with dimensions of 3x3, 3x4 or 3x5, and rooms where acceptable area, and the total cost of construction is not very large. You can of course opt for and the structure of 5x4 m, but most owners are choosing the optimal structure with the parameters of 4x6 m. - compact outside and spacious inside the structure where the tape type of the base used.

During the construction of baths with their hands should calculate all the dimensions of the future structure and only then start to work. Since the choice of the total area has produced, number of rooms determined the rest of the work scheme will look like this:

  • determining a kind of foundation;

    Drafting taking into account the soil type, topography and other parameters;

  • marking a building on the site;
  • excavation work on digging pits, trenches or excavation;
  • registration prepared depressions in the ground;
  • pouring mortar or laying of other pictures.

By following this simple plan you can properly plan construction operations and execute them in slow mode with your own hands. It should tell a little about each stage of the work that subsequently arose nuisance or delays in construction.

The project to develop is not necessarily their own. But if it is possible to do all the work with his own hands, rather than relying on the experts, you need to consider when designing a lot of nuances.

Defined with a view of the foundation costs, starting from the type of soil on the site and its topography. Here it should be taken into account and the weight future bath (the material of which it is performed, the number of floors, the total area).

The marking is performed only when all the values ​​of the future buildings can be seen on paper. Mark the area under construction is not very difficult and it is quite possible to do with their hands.

Digging trenches and pits also afford to carry yourself. An exception may be a deep pit, which is required under the base of the building on the muddy bottoms. It is better to hire a technique to accelerate the work. Use the tape on the base form of such ground is impractical.

The remaining two stages of works are almost always do-with their hands, as they always are standard for all buildings.

The type of soil largely determines which option is best to use the foundation on the site:

  1. On dense soils should be fine columnar base medium or strong penetration.
  2. Sandstones should choose a type of belt foundation, as a more durable and does not react strongly to soil movement.
  3. Silty soils can not be trusted much, so pile types of bases and solid foundation will be here most appropriate.
  4. Clay soils often lie layers of harder rocks, so a belt or a bar type strongly recessed base should be fine.

The relief also strongly influences the choice of the type of foundations for the construction of baths. At sites with a strong bias for economy and durability of selected types of pile foundation. And where there is a large alternation of peaks and troughs is better to dig a pit or a general to apply all the same pile.

Freezing depth of soil on the site is directly proportional to the depth of the foundations of the future foundation. It is often necessary to move deep below by 20-25 cm (especially if the room is planned volume). But for light 3x3 buildings, 4x4 or 4x6 m doing deep pits or trenches 0.8 meters.

It should initially to calculate the markup and width of the trenches or pits for columns. It usually exceeds the size of the wall at 10-20 cm (for formwork and backfill).

On markings on the ground depends on the curvature of the walls and their sizes to be correctly done. Therefore, this stage is worth special attention and careful work.

First, you should choose the most distant point of the future structure. It should be a mark of the outside wall. At this place into the ground hammered peg, which will be a reference point for further marking operations.

From the first stake along the far side of the long is necessary to measure the magnitude of the future wall. Here it is necessary to calculate the maximum correctly. For the structure of 4x6 length is more than 6 meters, as even worth considering, and the width of the walls with the addition of a distance to the formwork. Therefore, when the wall width 40 cm, length of a mark-up distance should be:

6 m + 2 + 80 cm x 20 cm = 7.20 m.

At this distance, and set the second peg. Then thread the construction of these pins are interconnected.

From perpendicular to the first peg is measured for 5 m 20 cm small wall and the third fixed peg. The same operation doing a second stake. Upon receipt of the perimeter will be held outside the line of the future foundation.

The inside of the base of the structure must be done strictly according to the size of 4x6 m, and from erecting a string rectangle. According to the obtained markup lines and costs to dig a trench under the belt type foundation.

One should not forget about the internal partitions. Their better dig immediately after the core box under the base.

The same principle and monolithic appearance. But should dig a pit for a building of the outer sides. A value for the columnar types remain the same, but the pits are at the corners and every 2 m. Total obtained 10 pieces.

Major work on the creation of foundation

After marking works and trenching (pits, the pit) should proceed to their interior design. To do it right, you need to know the procedure works:

  • put on the bottom pad of sand or gravel small fraction;
  • create a waterproof roofing material through a roll (in two layers) girded entire strip footing;
  • reinforced trench (hole) associated with steel rods or wire welded to a strong structure;
  • set the formwork on the outer edges of the pits (trenches), strengthening its props;
  • pour the prepared hole solution.

All stages of the work are the same as in the construction of any building. But it is worth remembering that fill belt type base costs evenly, leaving no voids. Then the foundation is strong and solid.

FOUNDATION FOR BATH 4x6 OWN HAND BAND - GREAT BATH

Strip foundation for a bath, from excavation to concrete pouring

Fortress foundation of any building is the key to the reliability of the whole structure. In this article we will look at how to install the belt foundation for a bath with his hands so as to be sure of its reliability.

Picture perfect ousted foundation
Picture perfect ousted foundation

General provisions

To choose the type of foundation depends on:

  • size of the building;
  • the proximity of groundwater;
  • layout of rooms;
  • used building materials;
  • soil composition.

cheaper options can be used for reasons of economy, such as:

  • pile;

Base on stilts

But, despite the fact that their price is cheaper, they significantly lose on aggregate qualities ribbon-like structures, which represent a concrete robust frame around the construction of the perimeter (see also the article "pier foundation for a bath with his hands - real master can do anything") .

Made strip foundations under the bath 6x4 with their hands at their summer cottage
Made strip foundations under the bath 6x4 with their hands at their summer cottage

What are the qualities so isolated it is this embodiment of the foundation?

Let's consider them:

  • Very high strength. Can withstand even the weight of a two-story house.
  • Low thermal conductivity. That in the case of the sauna, in which the presence of high temperatures is expected, it is doubly important.
  • Ability to create further cellar or subfloor.

The only negative, consisting in a higher cost is more than compensated confidence in high quality and durability.

Tip: In order to budget savings can be used melkozagublenny version of the tape base. Costs are much lower due to the smaller volume of concrete screed and strength is enough for one-storey saunas.

Installation

Instructions for installing the foundation consists of several stages:

marking

Mark up the line for future walls

Created strip foundations under the bath with his hands must be absolutely flat and straight angles.

For this:

  • We perform cleaning of the construction site from all sorts of debris.
  • Eliminate grassy carpet.
  • Align the territory.
  • Prepare spirit level, measuring tape, pegs and nylon rope.
  • Make a mark on a variety of angles.
  • Measure the distance from it corresponding to the length of the wall, plyusuya while still half a meter in both directions.
  • The obtained points hammering pegs and stretch the rope therebetween. So we have marked the future location of one wall and two angles.

Graphical representation of the Pythagorean theorem, which in our case a and b - the adjacent wall, c - diagonal between adjacent corners

  • Similarly, set the mark for all other angles.
  • Check the squareness of the walls.

Tip: To check for the presence of angles of ninety degrees is recommended to use the Pythagorean theorem. This is the best way in which you do not have vymeryat degrees, and only folded squares values ​​sides of adjacent walls and prirovnyat received and assume the square sum values ​​of the diagonal length of the room. If the numbers are equal, then a right angle.

  • Further we note the position of the internal walls and furnace.

digging trenches

Apparatus strip foundation under the bath - earthworks

After the implementation of the markup necessary for her to dig channels for future pouring concrete (see also the article "The foundation of the bath under the stove: forms, tips and a description of existing structures").

They have their own size requirements:

  1. The depth of the strip foundation under the bath depends on the quality of soil construction site:

  • soft soil - at least one meter;
  • hard rock - about fifty centimeters.

  1. The width of the trench is calculated required a bit more complicated:

  • width of the outer wall of the planned increase by 10 cm with a dense soil and 20 in soft - it will be the width of the foundation;
  • adding to the resulting number More 5 cm - an optimal width of the trench.

For interior partitions can be made smaller than the width, but only with the condition of having solid ground.

Creating a cushion

sand bed

Before placing a strip foundation under the bath, it is necessary to fill bed of gravel or sand thickness not less than twenty centimeters, which is:

  • It prevents the deformation changes of the building;
  • absorbs pressure;
  • creates a thermal insulation for concrete;
  • It protects against the harmful effects of excessive moisture resulting from snow melt or heavy rains.

Construction formwork

Photos wooden formwork

Strip foundations under the bath with his hands is necessarily using formwork - wooden structure follows the shape of the future foundation. After the concrete has a liquid state, and it should set the parameters of solidification.

Often such a construction the stationary or removable type.

Tip: for a bath is recommended to use a stationary formwork. Because it is in this case more and enhances thermal insulation.

Is as follows:

  • Along the edges of the support for the wall mount channel future formwork.
  • Bring down panels from boards. In the case of a removable option should ensure that the screws are not sticking out from the inside, otherwise the product will be difficult to remove.
  • The protruding part of the earth must correspond to the planned foundation. For a removable structure is more convenient to five centimeters higher.
  • Minimum period to eliminate the wooden boards of a fortnight.

Reinforcement

Metal gratings for strengthening structures

Reinforcing frame significantly increases the strength and elasticity of the concrete, which will sustain the future of the foundation all directed at him loads without destructive processes for themselves.

  • We are trying to drive into the base of the reinforcing bars a width of about twelve millimeters at short intervals.
  • With the help of the wire fix it to the horizontal metal bars.

Hint: it is not recommended to use a welding connection, because it violates the plasticity of the product.

It is important to make a strong attachment, shaky grid loses some of its properties.

When implementing melkozaglublennogo foundation can be dispensed only horizontal reinforcement.

concreting

Pouring concrete

Last final stage.

The following solutions can be used for it:

  1. The factory concrete. The best solution in terms of quality and effort. But at the same time and more expensive.
  2. A mixture of cement and sand. Prepared in a ratio of one to two and adding water after thorough mixing. It has rapid solidification, due to which the fill should be done in a hurry, and high strength.
  3. The mixture was crushed stone, sand and cement. The ratio used is 5: 3: 1 respectively. It characterized by long period of solidification, and lower strength. But, due to the use of gravel, the cost of such a solution is the lesser.

Work is carried out as follows:

  • Mix first dry mix, in that case if the choice fell on handwritten manufacturing.
  • Top up with water using a divider.
  • Again stirring until mushy state.
  • Fill the resulting mass.
  • Bayonet shovel pierce substance to remove air from it.
  • Cover with plastic film and moistened periodically until complete solidification.
  • After drying, the concrete cover its waterproofing layer.

conclusion

Either the structure is very important reliable foundation. Because that's what it turns out to be a lot of pressure throughout the building. Bath or sauna is no exception, added only increased demands on thermal insulation (see also the article "Sewage in the bath: manufacturing principle").

We looked at how to make a strip foundation under the bath alone. This will greatly save the family money.

Despite the fact that the process itself is not a big deal. The main thing only to do all the installation steps carefully in accordance with the recommended instructions.

Videos in this article provide additional material on a strip foundation for a bath.

How to make a strip foundation for a bath with his hands

The simplest room in the form of one-storey buildings with a steam room, a waiting room and a tiny dressing room area will require up to 25m2 on the site. No matter of what to do and how to build the walls of the roof of the bath if you do not want every year to deal with cracks in the walls of the steam room and patch the liner, be sure to make the foundation. Place the tape minifundament for a bath requires a lot of time, effort and money. Better to do immediately strip foundation for a bath with his hands, it guarantees quality. All the same, it will be cheaper than ready-made bath remodel or disassemble almost built, but a cracked bath body and start a small building with a problem - how to pour a strip foundation under the bath.

When do you need ribbon foundation baths

Even a complete box bath, the thickness of a brick, unable to withstand the loads and stresses in the structure occurring when soil subsidence and deformation under the weight of the masonry. If you do not make the tape foundation, even clinker brick and rubble masonry in the walls of the bath and allowed to burst fractures. The weight of the bath design also affects the shape of the building, the size of the box walls and the size of the roof. The larger area basis, the larger timber and logs need to make the frame of the roof and the ceiling, the greater the pressure on the foundation soil.

You can make the walls of the bath timber or logs, but in this case, in violation of the soil bearing capacity of wooden log can produce roll and sediment that could break the internal bulkhead baths and roof rafters. Timbered buildings can be put on the pipe piles on which to make a tape of the foundation frame of the timber. This option allows the foundation to level the load and make the walls of the timber bath.

What is the depth and breadth of the foundation tape to pour, determined by the nature of soil for future construction of baths:

  • For a dense mix with a lot of rocky rocks large and small fractions of the strip foundation depth may be limited to 40-50 cm As a rule, dig deep full basement with his hands very hard.;
  • Dense thin sand mixture with a power layer of at least one meter. This soil foundation operate 60-70 cm deep with compulsory controlling the drilling in the foundation of the future corners of the box;
  • Any soil with a content of loam or clay, any rock capable of absorbing moisture. In such cases it is necessary to make a trench for the foundation to a depth of 25-30 cm plus freezing.

Important! On soils with a high content of sand or sandy loam, you can make a few extra rows of piles of logs within the contour of the tape substrate. This option helps maintain the bath stability when under the concrete ribbon begin to rise groundwater.

Each of the piles need to "bind" the walls of a bath in the base stacking of the timber beams. Moreover, such an additional embodiment of the foundation in the bath can be used as the basis of the timber for heavy iron furnaces with a facing brick.

On dense stony soils can count on melkozaglublenny strip foundation for a bath. Usually it exits stony fraction marl, dolomite or monolithic arrays of heavy rock. In such cases, the trench under the foundation tape shallow obtained - in 30-40cm depth. Compressed rocky base plays the role of the foundation slab. In these cases the strip foundation is needed to anchor the building to the rocky base.

Strip foundations under the bath 6x4 with their hands

Before you start to dig a trench under the strip footing, would be to perform accurate snap drawing a bath on the ground. When the amount of the walls 6x4 trench width is 10 cm to the side of wider design thickness masonry plus 5cm for technological needs formwork installation. Subtotal for bath with wall thickness of 20 cm trench width of 45 cm. Accordingly, the marker must pull cord on the stakes perimeter 6,5h4,5 m.

Tip! In any foundation works with trench depth of over 60 cm is better to use specialized equipment for cutting trenches or ditches. But before you rush out to the tractor portion of a bath, make sure there is no water, gas or electric communications.

If the bath is provided masonry brick oven, in this case it is necessary to do a full foundation under the stove and main wall of brick, to which will was attached stove and chimney. Trench timbering and under the inner tape base is the same as the perimeter of the main bath. Foundation for the furnace runs a separate plate, and with the foundation tape walls of the capital does not bind.

For the tape base is recommended to use ordinary cement 400-th mark with a small addition of plasticizer in the concrete of surfactant or soap. On one part of cement is used three measures of quarry sand and three to five parts gravel. Very good filler for a foundation considered sea and river pebbles, soaked before laying into the ground foundation for 20-30 minutes in a soap solution.

How to pour a strip foundation

Preparation for concreting is performed in two stages. For the foundation to a depth of freezing order filling is slightly different from melkozaglublennogo options. The most robust embodiments of the tape base is performed in the following sequence:

  1. Initially, the bottom of the trench stacked layer of gravel fraction 15-20 mm, a layer of 60-70 mm, and repeatedly tested rammer. Next, lay the geotextile fabric layer and backfilled with sand 70-100 mm;
  2. At the next step is to put the film waterproofing and begin laying reinforcement. If the foundation depth of 60 cm, the reinforcing bars can be divided into two layers. Origin laid 40-50 mm from the waterproofing, the second at 40-50 mm from the surface of the concreting future. Ligament fixtures with vertical uprights necessarily need to perform;
  3. Installing formwork will form the concrete foundation above ground, and significantly reduce the consumption of concrete. even concrete layer is 20-30 cm in height exerts pressure shuttering walls with a force of not less than 30 kg per linear meter, so the design must use a board of 25 mm thick;
  4. The concrete mix concrete mixer or twist electrical or interrupted bayonet shovel in a shallow container. This is done to increase the flowability of the mixture and displace air from the solution.

Tip! Before pour the mixture into the mold, set in a trench trimming pipes, through which a concrete mass are received through holes, through which hereinafter will be supplied with water and sewer pipes installed.

Pouring concrete layers is performed as the concrete income from associates. The first layer of 15-20 cm and a final layer of concrete is recommended to align the blade and handle electric rammer.

If a solution is not enough concrete, filling can be done in several stages, or layers. Each new layer should have a thickness of not less than 25 cm. In this case, each layer is recommended to gain a fiberglass reinforcement in the form of a grid-ligation. Such a frame of 4-6 valves is recommended to make sure for small strip foundations with embedment depth of 40-45 cm.

After filling the formwork with concrete covered with a damp cloth and plastic wrap. In summer, in the sun, poured concrete should be periodically spray water to prevent overheating of the casting.

Lapping strip foundation

Formwork with strip foundation should be removed after two days. As long as the concrete surface did not get even a preliminary strength, you need to trim and leveling the surface of the foundation tape on the horizon.

On the cast strip foundation necessary to make waterproofing and processing of concrete surface mastic asphalt and roofing material. After 10-12 hours of continuous footing perimeter needs to be done with mandatory dumping ground compaction rammer.

Strip foundation has always been considered for very cold bath so on top of concrete foundation always fit "warm" layer in 3-4 rows of hollow ceramic bricks. After alignment of the brick layer can be spread cinder block, wood-concrete or aerated concrete stone.

Pouring warm tape foundations under the bath

Relatively new is the way to make the insulation of the casting in the ground on the basis of porous polystyrene boards. In this case, for manufacturing shuttering tape bases used non-removable plastic plates, assembled and installed in a trench. Ready tile of expanded polystyrene are joined together end to end and are fixed by the metal spacer structures. After pouring the concrete fixes insulating material and leads to a complete insulation base bath.

conclusion

The cost of the cost of the cast strip foundation is at least 25% of the total cost estimate. In contrast to the walls, roof insulation or bath, alter misfolded foundation or to dismantle and make it in a new way is almost impossible. Therefore, to manufacture even a simple strip foundation should be approached as carefully.

How to make a foundation for a bath: step by step guide

Every owner of a country house or villa dreams of his own bath. Any construction begins with bookmarks foundation, in fact it must accept the full load of the weight of the structure. It's not hard to make a foundation for a bath with his hands, on this part of the construction can save considerably. After the construction of the foundation and so costs the owner of 40% of the entire bath.

As built the foundations for a bath with his hands with step by step directions, photos and videos will be shown in this article.

Where do you start work

No matter what type of foundation will be chosen for the construction of baths, the first thing you need to prepare the site for construction.

From the land of uprooting all the stumps, large stones are removed, remove other debris. Grass in the area is better to mow or pull out, not to leave the roots and stems. Then remove the entire pad sod - topsoil and remove it aside.

Now you need to partition. For this purpose, metal rods, valve type, and a strong inelastic rope. The most important thing at this stage - to postpone the right angle. You can do this great building triangle or improvised means.

Important! Each side of the foundation should be 5-10 cm longer than the estimated perimeter of the building.

Choosing the type of foundation

Determine which base is more suitable for a particular bath, it can be based on several factors:

  • the depth of the groundwater;
  • type of soil on the site;
  • the depth of the ground freezing in the winter season;
  • Building material;
  • Square bath.

Phased analysis of all components will help identify the most reliable foundation for the construction of a concrete bath.

Most often used for foundation tape melkozaglublenny 4x6 bath. However, this is not the only option. You can still apply:

  • pile-screw - constructing, when the site for the construction of a strong elevation changes;
  • columnar - for sustainable soil, on which there are no landslides and shifts;
  • pile-rostverkovy - suitable for unstable soils that are prone to fraying and shifts;
  • monolithic - Universal, is the most reliable, but at the same time, and the most expensive cost. One piece of concrete slab evenly distributes the load from the bath, not ground sags and construction does not deform or crack.

All kinds of foundations are used for the construction of baths, but most often, still use tape or columnar base types - for them and will be discussed in more detail.

How to arrange a pier foundation for a bath

Make a pier foundation under the bath 6x4 with your own hands is quite real. Particularly suitable is the foundation for a minor structures made of beams, logs, or foam-aerated.

Attention! The foundation of wooden logs or timber is necessary not only carefully waterproofed, but also to process an antiseptic agent to prevent rotting.

The bars can be constructed of the following materials:

  • brick;
  • concrete poured into the prepared formwork;
  • asbestos-cement pipe;
  • metal tube;
  • solid concrete slabs;
  • wooden logs, or logs.

Tip! From whatever material neither constructed columns for the foundation, they should be thoroughly waterproofed. To do this, use roofing felt or bitumen mastic.

Most others are used for the columnar base pipe: metal or asbestos. Description of the installation process is as follows:

  1. Mark out portion is set at the corners of the valve and pull the rope.
  2. In every corner, in places of construction of partitions between the rooms and in the other the most critical points you need to install support.
  3. The ground makes a hole borer or other device. The diameter of the support hole should be slightly larger pipe diameter (3-5 cm). The depth of the wells should be such that the support not reached the depth of groundwater and soil freezing depth. In most cases, a depth of 50-70 cm is enough for the bath base.
  4. At the bottom of each hole is filled sand and gravel - these materials must complete the well by about a third. Pillow moisturize and ram.
  5. Apertures mounted tube. Previously they wrapped roofing material or coated with mastic.
  6. The distance between the pipe and the borehole wall is filled with sand or earth, wherein the tube is aligned by level.
  7. Asbestos cement is poured into the metal pipe or concrete, without adding to the top of about 30 cm. The support is raised slightly, so that the solution penetrated under its base.
  8. The concrete is inserted a metal rod - rebar.
  9. Concrete is poured up to the top of the tube.
  10. About a week waiting for the concrete pour, then waterproofing bars at the top and continue the construction of the bath.

Attention! Costs pier foundation is much less than the construction of the base tape. A strength of this foundation is quite enough for a small bath-house of wood or other lightweight material.

Building the foundation belt type

For smaller buildings such as a garage, a summer kitchen, a bath, you can arrange melkozaglublenny strip foundation. In order to calculate the depth of the trench to a base, it is necessary to study the composition of the soil at the site.

If the soil relates to a stable - not crumbly, moderately humid - it will suffice trench depth of about 40 cm to more unstable soil -. Black soil, peat, sand - this value should be increased up to 70-80 cm.

The width depends on the material of the foundation walls bath: for lightweight structures will suffice 25 cm, and for stone or brick walls must be at least 35 cm trench itself, thus, should be wider - somewhere 5 cm..

Step by step description of the process tab strip foundation under the bath is as follows:

  1. On the flat areas are the lowest point - from her foundation and construction will be carried out. In order to melt and rain water bath was not damaged, and promptly descended from the portion around it, it is necessary to make a small deviation. Slope done in any direction, except for the north (it is enough just a couple of degrees).
  2. In the corners of the foundation of the future set of metal bars, with their help pull the rope. In the case of strip foundations must be two circuit (internal and external). Therefore it is necessary to pull two parallel ropes between which leave a distance equal to the width of the foundation, plus 5 cm.
  3. Begin digging a trench. If the soil is too loose, the trench made in the form of an inverted trapezoid. Bottom of the hole should be smooth, it is checked using a spirit level.
  4. Now you need to make a gravel-sand bed - it will provide the basis for sustainable, smooth out the possible ground motions. At the bottom of the trench sprinkled sand is moistened with water and ram. Then pour gravel, too, ram, and now - again sand. Alternate layers as long as the trench is filled halfway.
  5. In the case of very unstable soils can be further strengthened for foundation - put a layer of brick or stone on a gravel-sand bed.
  6. Now proceed to the construction of the formwork. Its churning of the boards, thus, the entire fixture must remain outside, there should be no gaps between the construction parts. The smoother will be the formwork, the less will have to grind the finished foundation.
  7. At the bottom of the trench is laid reinforcement of metal rods and wires.
  8. On the inner walls of the formwork is laid polyethylene or roofing material for protection against moisture.
  9. Pour the concrete formwork is necessary at a time. If a job to do breaks, the foundation will be laminated and brittle. Therefore it is better to order a concrete mixer, and to acquire the necessary amount of the prepared solution.
  10. The formwork can be removed after a week and continue to build a bath - only three weeks later, when the concrete attains sufficient strength.

Attention! For the construction of the basement on the street should be zero temperature - optimally to +5. If it is too cold, concrete hardens evenly, resulting in its brittleness.

During the construction of the concrete foundation is important to remember that any air bubbles in the bulk solution, sooner or later will lead to the destruction of the material. Therefore, concrete can be cast from a height of 50cm, and after pouring vibromashinkoy compacted or at least, a rod pierced solution in several places.

Important! If the bath is a real stone oven, it is necessary to make a separate foundation. This may be a belt-type base or solid concrete slab.

conclusion

Yourself to build your house, of course, not everyone can. But you can start small and to start to build a bath. Lay the foundation for building a small 3x3 or 4x5 does not take much - this is quite cope and novice builder. A lower cost base, created on their own, sure to please the owner, and will not save on the finishing favorite bathhouse.

The foundation for a bath 3x4 with their hands

One of the first and most important steps in the construction of any building is the arrangement of the support structure capable of stoically withstand the load created by the structure and ensure its preservation and integrity in service for many years. It is no exception and compact room of 3x4 meters. Despite its modest size objectively, this building also needs a high-quality and properly installed the supporting structure.

The foundation for a bath 3x4 with their hands

During the study information below, you will learn how to choose a suitable foundation for a bath of 3x4 m, on the basis of what parameters determine the choice of a specific design, as it is to correctly calculate and immediately erect. The resulting information will help you to choose the best suited kind of support and optimum dimensions, as well as to refuse third-party providers of services, significantly saving the budget allocated for the construction of baths.

bannomu to the foundation requirements: choose the best design option

Requirements for bannomu foundation

By the foundation of any building shall be presented two key requirements. Firstly, the support structure should be as reliable and durable. Secondly, the foundation of the design should be such that the soil seasonal shifts did not render it a significant impact.

When choosing the design of the foundation and its dimensions, in addition to all the other factors you need to take into account the type of soil at the site of construction and the depth of soil freezing, according to which is determined by a significant indicator as the depth of the support structure. In a study of third-party guides, you are probably faced with the recommendation not very competent authors lay the foundation to a depth of 60-80 cm, etc. In some cases, of course, this advice is relevant, but not always. The bottom line is that in different regions of the country the soil freezes to a different depth and this must be taken into account. Information regarding the data points given in the following table.

The depth of soil freezing by region

The depth of soil freezing

In addition to the depth of soil freezing, it is necessary to take into consideration its type. The images show what are the different types of soils and how they look.

Types of soil properties, composition and type of soil classification soil types

laying depth dependence of the level of the passage of groundwater and soil freezing reflected in the following table.

Table. The relationship and depth of the foundation soil characteristics

Based on the foregoing, it is possible to bring the table with recommendations for the choice of the type of foundation for a bath 3x4 meters in accordance with the properties of the soil at the construction site.

Boards are found less frequently, as can be used in the complex is not with all types of soil - the soil is too mobile simply destroy the plate.

Slab foundation - the durable base view which is widely used in private construction

Pile foundations are the most versatile, but the purchase and installation of screw piles directly leads to an increase in the total cost of the work that is permissible is not for everyone builder.

The foundation on screw piles

More budget option support structure largely similar to the pile base, - a pier foundation.

pier foundation

In view of the above, we invite you to read the instructions on the calculation and construction of the most frequently used types of substructures: the tape base and a columnar structure.

Calculation of the foundation: the basic principles and important notes

The procedure for calculating the bases for the tape and columnar types will vary. Objective: To determine whether the base with the selected parameters can withstand the load created by the developer of the selected building materials as well as precipitation.

Calculation of the belt structure

In this example, the system calculates a monolithic concrete and granite rubble. The following image illustrates the plan and dimensional characteristics is building the base. Taking the following recommendations, you will be able to adjust the support plan and the procedure for calculating loads.

Plan and dimensional characteristics is building bases

Our tape base has dimensions of 4x3 m Design -. Inclined, widening towards the bottom. Thanks to this feature will provide a higher resistance forces soil swelling at the site.

The strongest stresses in the construction under consideration will be exposed 4-foot portions, since ceiling joists and rely just on the side walls. Let's calculate what kind of load will create an overlap and lags bath by 1 m of the foundation sole. To find the total size of the load, it is necessary to determine what kind of load on the concrete structure will create snow, roof construction, floor and walls. Additionally taken into account the load created by directly manufacturing material of the support structure.

Snow loads determined by the product of the regulatory burden produced snow in a specific area on the cargo area of ​​the roof structure to support system 1 m. Regulatory snow load value is determined by appropriate documentation - here this SNP under number 2.01.07-85. You can also be guided on a special card.

Map of snow loads

Additionally standardized values ​​of coefficients used when the snow load, will be given in the corresponding table.

To determine the cargo load of the roof structure on the meter base, it is necessary to divide the total area of ​​the roof on the support length. For calculation, thus, only the values ​​of length of the side bands are used (4 + 4 = 8 m). The length of the end portions (3 + 3 = 6 m) in this calculation does not appear, since roof beams, as noted, will be based in particular on the long bathroom wall.

Snow load count in the following order:

  • We find the total area of ​​the roof structure. To do this, multiply the value of twice the length of the roof and the length of the ramps roof eaves. The length of the slope is calculated as: 3/2 = 1,5 / cos45 = 2,86 m the total area of ​​the roof structure is calculated by: 2 * 2.86 = 5.72 * 4 = 22.88 m 2 (rounded up to 23 m2).
  • We are counting the cargo area of ​​the roof support structure for a meter: 23/8 = 2.88 m2;
  • an exemplary system for supporting forward region included in zone II of snow loads. Display specific snow load here be 70 kgf / m2 (the values ​​for the other zones will show in the table). Calculated as follows: 2.88 * 70 = 202 kgs.

Table. Specific loads for different zones

We determine the load of the roof structure. We need to find the value of the load from the projection square meter roof system in the horizontal direction. We is 1.5 m tiled gable roof. It is mounted at an angle of 45 degrees.

We select the appropriate value in the following table.

The load on the foundation of the horizontal projection of the roof

And consider: 1.5 * 80 = 120 kgs.

To determine the load from the slab previously look into the table.

The loads on the supporting structures of overlappings

In this example, a cargo area also falls on the sides of the support structure (based on the overlap side walls bath). Bath cargo area of ​​overlap for each meter of foundation system find as follows: 4 * 3 = 12/4 = 3 m2. The density of the wooden floors - 300 kg / m3. The load is as follows: 3 * 300 = 900 kgs. If the overlap in your bath is made of reinforced concrete, the calculations use a value of 500 kg / m3, instead of the mentioned 300 kg / m3, are relevant to timber structures.

We know what kind of load will create on the base of the outer bath walls. The pre-study the following table.

Table. Pressures created walls bath

We take from the table above load value, then multiply it by the height of the walls of our bath, and then - on the wall thickness. Assume wall height of 3 m, the thickness take at 0.4 m. Our walls are constructed from timber / lumber. We calculate: 3 * 0.4 * 600 = 720 kgf.

To calculate the load from the base indicators multiply volume meter tape and its manufacturing material density. Density take from the table.

Table. material density

We make the foundation of concrete and use granite rubble. Volume meter tape particularly in our example - 0.45 m3. Find load: 0.45 * 2300 = 1035 kg.

It only remains to find the complex load per 1 m of the sole belt structure in the cross section A-A (it was shown above).

We summarize the calculated values ​​of: 202 + 120 + 900 + 720 + 1035 = 2977 kgf. The supporting structure with the cross section has an area of ​​50 * 100 = 5000 cm2. Determine the ground pressure: 2977/5000 = 0.6 kgf / cm2. We build on the plate-clay soil. For a comparison of the estimated soil bearing capacity equal to the index of 1.5 kgf / cm2. Consequently, loads are more than acceptable, and the foundation with such parameters will serve well for many years. Take the estimated comparison of load capacity of your soil can in the following table.

Table. Estimated comparison of bearing capacity for different soil

Calculation pier foundation

We calculate the pier foundation. For its production using reinforced concrete. With exemplary scheme can view the next image design.

Scheme columnar foundations

Note! In the picture shown the foundation plan for the building size 6x12 m to 3x4 m bath parameters remain the same, only the change amount of the supporting pillars (standard recommended to install them in 2 m, i.e. each wall will have to rely on post 3 -. Of 2 in the corners and in the middle of length 1).

It is the top section supports 400x400 mm at the base - 800x800 mm. Specifically, in your case, the size may vary, be guided by the situation.

We find the total load of the sole reliance on the soil. To do this, we need to subtract the one found in the previous calculated load weight support system: 2977-1035 = 1942 kg.

Multiply load indicators generated in the interval between the supports: 1942 * 2 = 3884 and add to the value found one weight bearing. Each of the applied contact supports having a volume of the order of 0.25 m3. The density of the concrete used was specified in the table above. pillar array is considered as follows: 0.25 * 2500 = 625 kgs. Load one pillar on the ground will be: 3884 + 625 = 4509 kg. Each column has a support surface area of ​​6400 cm2 (found by multiplying 80 by 80). In this example, the load carrying capacity of the soil is 1.5 kgf / cm2. To determine the maximum possible loads do the following: 6400 * 1.5 = 9600 kg. The resulting value is much higher than in the found contact loads (4509 kg).

Pier foundation with such characteristics will safely transfer loads generated bath 3x4 m, and even "stir". If desired, support structures may be proportionally reduce the dimensions - most importantly, to the estimated total load does not exceed the limit.

In this arrangement pier foundation will require approximately 3-4 times less than concrete, ceteris paribus, than the band support. Significantly reduced and earthworks. In the next section we offer you to get acquainted with the results of calculations of the volume of material required for the arrangement of the tape support structure. Consumption of concrete to fill posts in proportion you can determine after taking into account the above information with respect to materials savings.

Calculation of the foundation fill materials

The chosen interior layout bath depends base configuration of the belt, and from it - material consumption. In the case of 3x4 m bath interior layout options baths bit - we'll show them, and you choose the date for your event. The foundation will be poured with concrete 200th brand - the compact bath for the specified size is enough.

In our area the soil freezes to 80 cm. The tape laying 20-30 cm below the specified value. Take 110 cm width of the tape (A) equate to 3 m, a length (B) -. To 4 m, a height (G) - to 110 cm, a thickness (D) -. To 40 cm, depending on the layout, the calculations will be appearing new values. They further describe the relevant sections.

Table. Construction of the strip foundation

First, remove the debris from the site, and in general, all that will hinder us in the process of doing work.
Second, remove the fertile upper soil ball (usually its height is 150-200 mm). If you do not, rotten plants in the future will spoil the foundation. The soil is better to try to shoot the level and carefully leveled - it will simplify the process of partitioning, followed by base (do not have to spend time on the definition of the highest and lowest corners, which will save time).
In the future, the site space not occupied by the concrete ribbon, it will be necessary to fill the compacted soil, free from all sorts of organic matter.
We leveled the ground level and can start counting from any angle - height differences will not.
At the location of each outer corner of trying to drive into the ground rebar or wooden block. We measure the distance to the next corner and trying to drive there is a new bar / rod. We stretch between landmarks hammered rope. Repeat for each corner of the tape.
Mark the corners of the tape, we get a pair of adjacent bars (as shown in photo). For convenience, connect them to the top by a horizontal crossbar of the timber.
We measure the length of the diagonal. If the same - all right, if the costs - we made a mistake. We repeat the markup process more closely.
Digging the trench in accordance with the markings. Guidelines for choosing the optimum depth of trenches cited earlier. The soil is not remove - it we then use to fill in the depressions formed in the first stage of work (referred to in the relevant paragraph).
The bottom wall of the trench and aligned by level and compacted. If the soil crumbling, set of temporary formwork boards.
Using a clean fine sand. The thickness of the infill layer - 200 mm. The higher figures heaving soil, the greater the need to pour sand (up to 600 mm or even more).
The sand is more convenient to fill a small (10-15 cm) layers. The photo shows a device for manual ram sand.
On photo - one more variant devices for manual tamping backfill.
To better rammed sand sheds its water. Do it better before laying the material in the pit, not to scale.
The spirit level check the flatness pillows. Eliminate differences, removing excess sand or adding it where filling is insufficient height.
Note! In areas with a high groundwater level, instead of completely sand cushion expedient to equip the filling of sand and gravel in a ratio of 1: 1.5. Rubble is usually filled up the bottom sand.
In the above calculations previously discussed which materials and quantities needed for arranging the formwork. In the diagram shown in detail, of what elements is this design.
You just have to prepare the required number of pieces, hold them together with the screws (to make it easier to disassemble in the future) and set in the trenches.
In the photo you can see how the reality looks set formwork for strip foundation.
The formwork can be laid a layer of waterproofing material (e.g., polyethylene films). The presence of such care will eliminate moisture from the concrete solution.
The calculations indicate how much and what kind of fittings to be used for strip foundation of a design. Follow the recommendations.
A mesh or a "on the ground" (then the finished mesh is placed in the formwork) can be done directly in the formwork (vertical rods, then perpendicular to it, attached horizontal cross, which typically have a smaller diameter of the first 2 rows in set). The second option is more convenient to implement, otherwise no differences between them.
For connecting rods at the intersection using a binding wire or special fixers for fittings (a more convenient option). Strengthen the weld do not recommend - will serve such a design is less.
Important! Reinforcing mesh can not be put directly on the foundation - it will lead. It is necessary to ensure a minimum of 5-cm gap between the pillow and rods. To do this, use either resistant stones (cheaper) or special clamps, stand (it is more convenient, easier and faster). A similar clearance must be provided between the reinforcing mesh and the "tip" fill.
As a reinforcing tape to the outer walls and support elements for interior partitions.
Solution can be purchased as a finished product if desired - save time.
Helpful advice! Even for arranging the strip foundation under the bath compact 3x4 m will need a lot of concrete (calculations cited earlier). Quickly cook it manually would be quite difficult - pobespokoytes better to buy or at least rent mixers.
Concrete preparing for the standard recipe: take a share of the Portland cement brand M400, it - 3 shares net of fine sand, in it - 5 shares gravel. We determine the amount of water by weight of cement - the liquid should be about half of that figure. The output is a homogenous mass of medium thickness.
Fill the solution uniform horizontal layer parallel to its leveling shovel and piercing the reinforcing bar to remove excess air (if possible, it is recommended to purchase / lease special adaptation - vibrator).
We see that the fill is aligned with the standards.
After pouring rattles wooden hammer or bar of the formwork walls - this will further ensure the correct distribution of the mixture.
Under the standard concrete hardens and gains strength required for 28 days.
Helpful advice! To react entered all cement, daily spill pouring surface relatively small amount of water (especially true for the warm season - with a lack of liquid pouring crack). After spilling the water polyethylene sheltering foundation (not allow solar heat too quickly evaporate water and provide further protection against concrete precipitation). If it is cold outside, polyethylene laid on top of insulation layer (it is most convenient to use foam, it is not afraid of water, is lightweight and easy to fit / removed).
Formwork remove not earlier than concrete hardens (it takes 1-1.5 weeks). In general, professionals recommend leave the formwork to the full set of concrete strength.

Making pier foundation for bath 3x4 m

Schematically, equip design can be represented as follows.

Scheme columnar foundation with grillage

We propose to make pier foundation using asbestos cement pipes as formwork. Pour solution will be the same as the belt structure. For reinforcement use similar rods. Preparatory activities - from garbage collection to remove the fertile soil of the ball - are performed in the same order. The layout is also done on a familiar pattern with the only difference that here we are celebrating at the site location for future installation of the pillars at the corners of each wall and partitions as well as the length of those increments up to 2 m.

Getting to the arrangement of the columnar base for bath 3x4 m, following the provisions of the table below.

Table. Make a pier foundation

stage rabotyOpisanie

Armed with a hand drill with a working "nozzle" corresponding diameter (often make poles diameter or 250 mm or 400 mm - depending on the anticipated loads on the base), prepare for the future recess supports. Yama is recommended to make a couple of centimeters wider than the future pillars (intervals in the future be filled with compacted earth or sand). Above ground poles typically derive at 200-250 mm. The depth was adjusted so that the pillars have been omitted below the ground freezing at 200-300 mm. Recommendations for determining the depth of freezing cited earlier.
The bottom of each pit is filled with sand layer. Recommendations for selecting the layer thickness, the composition and its alternative tamping remain similar provisions on arrangement of the tape base. To ram perfect beam of appropriate diameter with fixed top handles for greater usability.
Putting the reinforcement cage, focusing on the size equip column. Guidelines for selecting the rods characteristics, their bonding and size of gaps between the bottom and the top are the same as in the construction of the tape support structure. Additionally, there is recommended to leave a 3-5 centimeter gaps between the grid and the formwork walls (pipe).
A typical form of the reinforcing structure is shown in the photo. Frame shape is selected according to the shape of pipes.
Tube inserted into the recess and aligned vertically, in pipes place the reinforcing mesh and proceed to the next phase of work.
The procedure is as follows:
- pour in formwork concrete pipe at a height of about 5 cm;
- raise a pipe - concrete fills the space beneath it, thereby forming an additional support area;
- omit pipe;
- pour the concrete to full height.
Tubes vertically aligned by level / plumb.
The gaps between the pillars and walls of the wells fill compacted soil / sand. Tubes provide additional stability in any suitable manner, for example, by setting the temporary shoring or the pipe close obkladyvaya massive stone.
We reserve the concrete to harden.
Above the cured concrete waterproofing laid:
- smear layer of molten bitumen;
- laid roofing material, presses and leveling;
- repeat again.
The formwork can not be dismantled - it will not get in the way.
Continue construction is recommended after the concrete sets the desired strength, i.e., a month later.

Strip foundations under the bath with his hands: Step by step instructions

Construction bath of any material begins with the foundation poured. Among the various types of the most popular strip foundation. It is suitable for any kind of bath: made of bricks or blocks, beams, logs. The cost of the foundation is 30% estimate, so the bay his own hands can be good save. How to make a strip foundation under the bath with his hands according to the SNIP, we tell our readers in detail in this article.

Strip foundations under the bath is not difficult to fill in their own hands.

Features of strip foundation under the bath

The foundation is considered to be a zero cycle of any construction. But not everyone understands how important it is to perform a reliable basis for the bath. At the foundation is putting pressure several forces: the top of the bath, below the soil heaving and sides of the groundwater. Only reliable and correct foundation will stand for many years. Strip foundation is considered one of the most reliable basis for any size baths. To work with their hands we recommend choosing this option the base.

Tape base has a single monolithic structure.

Base consists of a continuous strip of brick or concrete, which leaves in the soil below the groundwater, and rises above the surface of at least 20 cm.

Strip foundations under the bath are selected in the following cases:

  • when the basement will be used for installation of technical equipment (pumps, subjects the storage area for cleaning, etc...);
  • the structure is too large and impressive weight, for example, the walls of the bath are collected bricks of logs;
  • the groundwater level is high.

Strip foundation uniformly receives the load from the bath and sends it down on the ground. Cap intended to protect the base against moisture, wind and cold. cap wall can simultaneously serve as a zero or a basement in the bath.

The price of a strip foundation below than the monolithic, but above columnar. He is considered the "golden mean", which is balanced on a combination of price - quality. And you can perform the work with his own hands, which will bring additional savings.

Tape - tape discord, or several ways to mount the strip foundations under the bath with his hands

Collect strip foundations under the bath with your own hands, you can use several methods. Either method has its difficulties, the pros and cons. Consider the features of each individual.

A tape base made of bricks

Mounting strip foundation is carried out using only the red bricks. Silicate White is afraid of water and quickly destroyed. The main thing you should look for when choosing a brick base it seams. Their carefully waterproofing, as the cement water tight.

Strip foundation of red brick.

Suitable brick base for dry sandy soil. If the groundwater level is too high, it is recommended to use a foundation of concrete with reinforcement and tie. Is placed on a bed of gravel and sand, carefully compacted. Do the job easy with their hands as a brick is not as heavy as, for example, concrete buckets.

A tape base of the blocks

heavy concrete blocks can be used to build a continuous footing. But to raise the material is possible only with the assistance of technology.

Strip foundation of small iron-concrete blocks.

For a small bath, you can own hands to collect the base of size 20-20-40 cm blocks. They are stacked in staggered rows and connected with cement mortar. Stack blocks on a marking on the sand cushion. Run the installation of the base block can be 1-2 days.

A tape base stone

Such a base is called rubble concrete. Installation is easy to implement with their own hands, as is the foundation of river stone and cement.

The foundation stone is common in the south of Russia.

Stone selected planar shape and approximately the same size. Its spread in layers of formwork and pour concrete. The result is a beautiful, sturdy plinth. Many choose tape rubble concrete foundation for a bath because of the low prices. Provided that the stone can be dialed somewhere nearby.

A tape base with permanent shuttering

method of mounting the bath base with permanent shuttering has been used recently. Is the basis of the two penopolisterolnyh plates. They are connected between them by metal pins. Inside made of reinforced wire harness and poured concrete.

A new kind of strip foundation with a permanent shuttering.

The base does not need extra insulated and waterproofed, and it is not inferior to the normal strength.

A tape base made of concrete screed

Monolithic concrete base and is the most simple and accessible for mounting their own hands. The previously prepared formwork placed related fittings and poured concrete construction. You must fill in one go, so you need a few people to bring a solution. You can use the concrete mixer and concrete is poured directly into the formwork from it.

Filler strip foundations under the bath is the most common.

After maturing formwork is removed, and the base is considered ready.

How to make a classic concrete strip foundation for a bath with their own hands will be considered in detail.

Learning to count the foundation under the bath

It is not necessary to pour the foundation, "the eye". It is necessary to purchase the material to perform accurate calculations. Only in this way will a reliable basis and bath will stand for many years.

For correct calculation of the base tape is necessary to determine two things:

  1. Weight future bath together with beams, and an inner roof arrangement.
  2. The level of groundwater and soil freezing on the site.

Determine the level of groundwater and soil freezing it will be possible to calculate a depth, width and height must be a tape substrate. Skilled artisans may analyze drilled to 8 wells for at least 2 m and conducting analysis of the soil. But you can simplify the task and perform analysis on their own.

Drilled at the site in a few places well and see at what level the water appear. If the level of groundwater is low, and dense clay soil, it is possible to select a weakly deepened by 40-60 cm. Take a tape base with bedding soil below freezing to central Russia-1, 60-1,80 m.

Load on top of the foundation can be calculated from special tables where indicated approximate weight of each element baths of different material. The indicators added to the approximate weight of the entire arrangement of the bath, stove, and people who are at the same time be able to receive treatment. soil resistance also calculate the tables. Footprint needs to be leveled top total load divided by the resistance of the soil. More details about this will cover in a future article.

Mounting strip foundation for a bath with his hands

Begin with the construction of the base pad clearance. Selected place in the bath, and removed the upper layer of soil 10-20 cm Planned -. Scheme markings made on the future base station. For work use wooden or iron pegs and rope. You must do the layout with an allowance to the basic dimensions of 15-20 cm.

Formwork for casting the strip foundation.

Next, the operations are carried out in the following order:

  1. Dug a trench around the perimeter of the base of the future. The edges of the trenches doing with the slope, it was convenient to lay the formwork. Trench digging deeper soil freezing at 10-20 cm.
  2. The bottom of the trench is filled sand cushion 10 cm. Sand is necessary to shed water and carefully compacted. Next, spread gravel on the pillow, and all again compacted so that the rubble hammered into the sand.
  3. The bottom of the trench is filled with concrete with a solution of 5-10 cm. Concrete serve as the basis for the foundation and the reinforcement will not go into the sand below the floor level.
  4. Formwork made of a wide edging board. The walls must be supported bars with spacing of 50 cm. It can be used in place of the old plywood boards, the formwork will be easier to collect.
  5. Installation of reinforcing ties. From rods connect the columns (3-4 rod) and spread on the bottom of the trench. At the corners of the design-wire.
  6. Formwork watered to further it is not pulling moisture from the concrete mortar.
  7. Concrete mortar is poured. Every 20-25 cm rake must work, releasing the mixture of the air bubbles. Thus, in the base will be less voids and the foundation will be more monolithic. Pour the base must be on the same day that it was not formed seams.
  8. The foundation closed tarp or old bags and throw once a day with water. So come during the week. Further, the bags are cleaned and allow the concrete to dry.

After drying of the strip foundation waterproofing using asphalt mastic and roofing material. It is better to start building the bath at once. Foundations need to settle, this requires a minimum of 1 month. More details can be seen in the video:

Make a strip foundation under the bath with his own hands, at first glance easy. The work is labor-intensive and requires a lot of time and effort. If you do not have free time to consult professionals. The price of a strip foundation starts from 10 t. P. / M². Remember, because how strong is the base bath, it depends whether the pair will serve your children and grandchildren.

The foundation for a bath with his hands: Step by Step Instructions

Build a sauna is the first desire of the majority of owners of private homes. But before the construction of questions arise: what material to build, what should be the foundation, etc. If you decide to install the foundation for a bath with his hands, then this article will become an assistant, and outlining in detail how to do it right...

Types of foundations under the bath

Bath - lightweight construction, but there are two-storey, choose the foundation necessary individually for each structure starting from the indicators:

  1. bath massiveness
  2. Specificity surveying in the construction area.
  3. The material from which the bath will be collected.

Fundam under the bath can be:

  • Monolithic. This is mounted on a floating ground with high-laid HS (groundwater).
  • Pier or pile-screw. It is used for wooden baths from a bar or round logs suitable for sandy soil.
  • Belt. The most common version is used on the ground with deep GW.
  • Mixed (belt pile +). Apply for baths rarely suitable for soils with quicksand, high occurrence of hepatitis B.

B may consist, depending on the material used in the foundation bath:

  • of bricks;
  • concrete;
  • of the blocks;
  • aspic or screw pile.

Foundations under the bath, in most cases lightweight, the installation is done by hand. Of course, there are companies engaged in the construction of the baths "turnkey" for the price of 10 000 m2, but in order to save the work easier to perform with his own hands. How to make a foundation for different types of baths, discussed below.

Installation of foundation under the bath with his hands

Each these types of foundation under the bath has its own characteristics, they must be considered separately. The only thing that unites the work of the choice of location for the construction, preparation of project plan.

How to choose a place in the bath tab

By choosing the site for the construction of baths should be approached seriously. The design is not based on one year, it must be placed correctly. There are several types of baths location: annexe to the main house, detached banya.Esli bath - this annexe to the dwelling house, the foundation of it is similar to the main reference. Do not make screw piles, when the main house is on the tape foundations.

Freestanding bath, then choose a place away from trees and other plantings. Bath will burn, smoke, sparks are not useful fruit trees.

Why do you need a project?

Construction bath with his hands requires advance planning. Regardless of whether the building will be registered in the future or not. The easiest way to use the typical project, these can be found in many networks. For any of the standard designs are attached photo. Photos need to understand more and to construction.

The plan also includes cost estimates, which are calculated all the costs and the necessary material to begin to build the foundation for a bath with his hands.

Mounting strip foundation

Strip foundation for the construction of a bath with your own hands can be performed in several ways. Pre-marking is carried out on the site of the future platform, for it digs a trench to a depth greater than 50 cm wider than the proposed laying of brick or timber at 4-5 cm. Dig a trench is better to start in the summer when the water table have the lowest occurrence. The course of subsequent work depends on the option selected:

  1. Pillow made of gravel and coarse sand. Each layer is compacted should have a thickness of 15 cm. It is possible to use the finished mixture CBC, but it is expensive. For better sealing sand recommended shedding water. Is grout (should resemble cream), poured onto a sand cushion. On the base mount or brick rubble stone. This tape will be mounted using the base bricks. Between each second row of masonry paving grid. Waterproofing roofing material (a layer-2).
  2. Another method starts with filling pillows ASG half, compacted in the same way as in the first case. It is important to cushion the surface was leveled. The next stage is placed in one row of bricks. Once assembled formwork boards and beams of 40x40 mm. Formwork height greater than 40 cm in the concrete is poured it on the basis of a moisture-resistant cement.
  3. The method is used for dense soil. Formwork set of dense material timber, e.g. slate. Laid sheets of slate need to overlap at 8-10 cm Formwork tightness. The formwork is poured sand that ram. The next layer is filled gravel, half-excavated trench. Structure compaction is filled with water. After starting to pour concrete. Concrete layer should not be more than 150 mm. Pouring concrete to perform necessary until the surface of the liquid cement mortar.

After casting any foundation, it is important to dry the structure. If drying is rapid, irregular, the foundation was cracked over time, may lead bath.

For uniform drying foundation on top cover with sawdust, burlap, suitable even PVC film. Once the essence of the design unwrap and watered again. So, it must stand under isolation for three days. Then the foundation under the bath open, give completely dry out, to stand. Minimum drying period of 2-3 days. After it is possible to cover the waterproofing example, roofing material in two layers.

To work on the construction of the foundation for the ribbon-type bath is necessary to consider several factors:

  1. fill height above ground level should be 20-40 cm. It depends on the level of occurrence of hepatitis B and the material from which the wall is collected, so for a bath from a bar height of the cap should be higher as the tree does not like moisture.
  2. Sand-lime brick is not suitable for the construction of the foundation, with the time it is destroyed by moisture. Red ceramic is produced at high temperatures and humidity it is not terrible.
  3. The tape has a width of 25-50 cm, depending on the material from which to construct bath.
  4. Concrete can be purchased ready-made, but it would be cheaper to make your own.

The composition of concrete (1 cube):

  • sand (coarse better, its pre-purified) 5% moisture - 1150 kg;
  • Portland cement (waterproof) - 400-500 kg;
  • stone chips (small or medium) - 1800-200 kg;
  • water - 170-175 l

Calculate the amount of concrete in the foundation of a bath, too, can be on their own. For example, the foundation tape height of 0.3m and 19m long accommodates 0,3h0,3h19 = 1.71 m3. Similarly, we can calculate the amount of any. But be sure to take into account further that under the stove, too, need a foundation, so the resulting volume you want to add more stock of 0.3 m3.

Installation of pier foundation

The simplest kind of foundation for a bath from a bar, or chopped logs. Good option for any type of soil, especially in the hilly areas.

The structure consists of columns, which are located at the corners of the future baths, under all load-bearing walls. The distance between the pillars 2 m maximum.

Pier foundation with his own hands to make simple, you can use:

  • wood or metal, asbestos poles;
  • lined with bars made of bricks;
  • drenched piles;
  • Screw pillars.

An inexpensive option is the wooden poles, but they need to dry before application and process tar or antiseptic deep penetration, such Senezh. For the columnar foundation of wood is best to use a larch and aspen, as these woods are not afraid of water and getting wet, getting only stronger. Set in a pre-drilled hole, which poured sand or ASG, reinforce concrete.

Brick columns of the most time consuming type of foundation with his own hands for a bath. But some efforts to this work, we can cope. Such a scheme can be seen in the figure.

Location is marked poles, removed the upper layer of soil and digs a hole in the future pillars of diameter greater by 10-20 cm. Lay sand bed of at least 15 cm. Column mounted on top of two rows of bricks.

Concrete piles are mounted with their hands most often, as though work and time consuming, but does not require special skills. Is drilled depth of at least 1.5 m and a diameter of at least 250 mm. The holes lay the skeletons of related accessories. Knit in advance reinforced rods 3 pieces, short connection and the binding wire. The construction of poured concrete. On top of the pile spread brick column.

It is possible to simplify this construction taking asbestos pipe section of 200 mm and set them in the well. Concrete is poured into the tube. The gap between the pipe and the borehole wall is filled with clay and gravel or compacted.

Pouring concrete into the pipe should gradually. The first time is performed on the shading ⅓, since the tube protrudes slightly thereafter. The second stage is poured more ⅓ portion and insert iron armature inside. Only then filled the remaining part. Completely dry out such a foundation in 5-7 days.

Another option is the pillar screw piles. They are sold ready and have the blades. In their land screwed by means of a bar. The only negative to perform the work with their hands alone impossible. It can be screwed to different depths, which is good for uneven surfaces.

casting technology pier foundation:

Installation of monolithic basement under the bath

foundation for any kind of use of the soil, but more often if there is a beetle. The construction of expensive, but the ground pressure is distributed evenly, and the bath is not skewed over time. There is no need to install a separate cushion and the foundation under the stove. Poured concrete structure or mounted on the frame of the reinforcement, ready to use or reinforced concrete slabs.

Installation of monolithic foundation for a bath with his hands achieved in stages :

  1. Digs a trench to the width of the foundation and the depth at 80-60 cm.
  2. At the bottom of the airbag is filled sand and gravel 15 cm.
  3. Blanketed waterproofing, for example, roofing material. Layers can be 2-3, the main thing that was not uncovered areas, overlapping of 10-15 cm.
  4. Then, a formwork and reinforced cincture, which again is filled with concrete.
  5. It is important to consider before casting where will drain pipe and install after setting it will be harder to do.

Select an option from the foundation can only host. A start at this point you need to up their forces and material resources. Perform all work with your own hands can be having some skill and see related videos and photos attached to this article.

FOUNDATION FOR BATH 4x6 OWN HANDS, ribbon, bar

Strong base - half of a reliable construction. Because of this, the foundation is given high priority, not only in the manner of work, but also the most important. During the construction of baths, this question is particularly relevant, as will withstand a considerable load. Functionality and size determine the shape of the future construction of the cap.

Construction of the foundation with his own hands

Table of contents:

The choice of foundation

The construction of the base of their own hands will not be a Herculean effort, if properly consider a number of characteristics of the ground:

  • load bearing capacity;
  • uniform compressibility;
  • distension;
  • shrinkage.

Based on these indicators, selected digestible foundation under the bath. There are several options:

1. Belt - the most common and erected their own. It received its name due to the similarity with a ribbon that runs along the walls of buildings. Suitable for almost any type of soil. The technology of its construction is not very complicated. Typically used for constructions simple configuration, no more than two floors.

Driving belt structure

2. The columnar - represents a number of poles buried under construction corners and interior walls in place of the compounds. The pillars are arranged at the same depending on the anticipated load, but not more than 2 m between them. Suitable such foundation under the bath of lightweight materials, such as frame or a wooden frame. The load on the base should not exceed 1 m 1 m 3 . Ideal for soil with deep groundwater.

Columnar base for bath

3. Tea - in the construction of the bath is rarely used. on its execution instruction includes pouring a concrete slab with reinforcement throughout the area of ​​a minimum thickness of 0.5 m. Such a base is suitable for building floors 2-3, complicated configuration on any ground form. Is particularly high prices, due to the high consumption of materials.

The foundation slab type

4. Pile foundations - is rarely used for baths because of its cost and make it will not be possible without the involvement of specialized equipment to the process of casting. The most modern version of digestible - screw piles. But it will not be able to perform. Piles are screwed into the ground, thanks to the screw tip, forces 2-3 people. Such a foundation is perfect in high groundwater, loose soil or uneven terrain.

installation of piles

Some experts distinguish separate pile-screw type with a raft made of metal piles with strapping wooden beam or I-beam, which gives additional strength to the chassis.

How to pour the foundation correctly?

For example, consider two of the most suitable type of base - columnar and ribbon.

As with any construction scheme, the process begins with site preparation and road marking. Needless to say, the size and configuration of the future building should be worked out in advance on the paper drawing. For example we can take a standard bath dimensions 4x6 m.

Originally produced cleaning of the proposed area of ​​debris, vegetation and turf. In order to properly make use roulette layout, squares, supporting stakes and rope.

Note: the site for the bath perimeter from a frame 4x6 m is increased by at least 10 cm from each side, depending on the type of the selected base.

Partitioning starts from the inner corner. The pegs are driven into the ground at the corners to form a rectangle of 4x6 m + 10 cm. Between the legs tensioned rope aligned gon. In order to check the accuracy of marking, laid diagonal ropes. Their length shall not differ from each other by more than 2 cm.

For the construction of strip foundation:

1. digging a trench along the intended circuit with parameters 4x6 m depth, depending on local climatic conditions. The width of the trench is defined as follows: base width 25 cm + 10-15 cm for convenience formwork installation.

2. The bottom of the hole is aligned horizontally, is sprinkled with gravel and sand layers of 10 cm each, moistened with water and thoroughly compacted. On the perimeter are driven metal rods or solid pins, of 3 cm thickness plank formwork going tightly fitted together. To connect using the bars, nails or special ties. The height of the formwork must be above the intended foundation 10-15 cm.

3. prepared formwork Inside stacked reinforcing section 12-16 mm in diameter. The rods are interconnected steel wires. For the formation of gaps between the frame and the bottom of the hole is enclosed broken brick.

4. To provide ventilation can laying ceramic tube diameter 6-8 cm at a distance of 2-3 meters from each other.

5. Pour the base must be continuously recommended to handle for one day. Concrete mortar is poured in layers of 15-20 cm, followed rammer. To remove air bubbles should be used with a simple vibrating hammer or a drill.

6. Formwork allowed to shoot a week after setting solution. complete drying process takes 3-4 weeks, after which you can continue the construction work.

Melkozaglublenny foundation
The technology of construction pier foundation includes:

1. Digging holes for pillars in identified locations on the drawing at a distance of 2 meters. For log 4x6 required to fill the order of 16-20 supports depending on the complexity of the bath configuration.

2. The filling each trench with sand 30 cm.

3. Pouring concrete pad 15 cm thick.

4. Adjustment of asbestos pipes vertically on the level. pole placement technique provides the additional use of different materials - brick, metal pipes, concrete, wood - depending on the static load.

5. Reinforcement of poles with iron rods. Sprinkle the outside and sealed with fine sand.

6. Concreting pipes - pour the solution should be to the top and carefully compacted.

7. Concrete Curing takes place much faster. These piles are ready to load in a couple of days.

Tips and tricks

It is also important to correctly calculate the depth of the basement location, in order to avoid distortions of construction, cracks and other negative influences. The clay, black soil, silty soils size is increased by 20 cm below the frost line. In other cases it may approach or unburied melkozaglublennoe base. For baths 4x6 m in the first embodiment will be penetration of 40-50 cm, in the second - 50-70 cm deep.

Ideal for the foundation will be dry, sufficiently dense homogeneous soil. Worst case - the soil of silt, peat, or fine sand. If the building is still to be on a similar soil, additionally at least 50 cm at the site of the installation base must be done to a depth of a sand cushion.

common errors

During the foundation reinforcement rods to bond many use welding. This connection reinforcement forbidden - is fraught with deformation of the base. Pour the foundation with his own hands is quite difficult and costly. Therefore, it is advisable to entrust the process of building the organization. Otherwise the quality can suffer foundation under the bath due to failure of solution preparation instructions.

To make their own solid concrete mix need M250 brand cement above, building sand, gravel and pure water in proportions of 1: 3: 3.5: 0.5.

Making foundation for bath 4x6 and 6x6

What will be your room, you decide for yourself, but in our articles, you can always find some useful information on how to properly build this room and where we should start.

Today we will talk about how to create a foundation for a bath the size of 4 x 6 and 6 x 6 meters respectively. In general, these two options differ only in size, but tell all the stages in detail, we have to.

In any construction of foundation works are fundamental, and if at this point to show carelessness or negligence, the further fate of the entire building can be jeopardized. That is why before proceeding to the main building, we recommend to study the given materials and make the appropriate conclusions. Below we will talk about what indicators should be guided at laying the foundation, how much material you will need for the job and what you are waiting for work.

You decide what will be your bathroom
You decide what will be your bathroom

Beginning of work

The first stage of any construction are always very interesting and enjoyable, as it does not involve hard work. At the initial stage should just quietly go on their own site and decide for yourself where you would like to see a cozy bathhouse. During this walk you will have to answer for yourself the following questions:

  • What type you would like to watch from the bath windows.
  • Where should go out the door of the bath.
  • If in future we plan to build a swimming pool the way it will be paired with a sauna.
  • If the bath is a veranda, then which side it will be located.
  • Depending on where you located sewerage, it will be necessary to conclude that wastewater from baths.
  • If you plan to heat the bathhouse with wood, then mark the right, where drovnitsa will be placed.

Once you decide these questions, you will need to take four small peg -. Metal or wooden length of about 70-80 cm These pegs you vobet around the perimeter of the future buildings (baths 4 x 6 or 6 x 6), and only after that you can start to take action.

Proper planning area - is the key to your comfort

Excavation

Bookmark any foundation begins with the time-consuming and arduous excavation work, that is, digging trenches or pits for formwork. But before we dig into the ground on the site is necessary to define the design of your future foundation. You have to choose from the following three options:

  • Strip foundation. This option is most often used for baths, as it is quite reliable and economical. And these two qualities always attract the owners of their own houses. Ribbons of this design tested under the bath walls, both external and internal, it helps to ensure reliability of the entire structure. Trenches for the foundation tapes must have a width of 20 cm and a depth of about 40 cm, the tape will naturally be closed at the perimeter of the bath.
  • Pillar (pile) foundation. This option is also often attracts owners baths, since it is the most economical of all, and requires a minimum of physical and material costs. But if you are planning a two-story building or room will be built of stone (block or brick), then this option is not very suitable. Thus, it appears that this method is only suitable for a small one-story wooden baths. To create a pile structure is necessary to determine how many holes you have to host. In the case of the bath 4 x 6 - it will be four pillars on the perimeter and two pillars at the corners of bearing walls. And in the case of bath 6 x 6 - this will be the six pillars on the perimeter and on the eight corners of the load-bearing walls. The depth of the wells for piles should be about 40-60 cm and the diameter (for circular pillars) - 20-30 cm, it is necessary to dig a pit square measuring 30 by 30 cm rectangular piles.
  • Tselnozalivnoy foundation. It is not often used for bath rooms, but if you plan to bath from the block or brick, as well as if your bath is a basement, you need just such an option. This method involves pouring concrete integral formation around the perimeter of the room. For this smooth pit dug 4 x 6 or 6 x 6, its depth is leveled approximately 50-60 cm. If you plan basement, then digging is necessary in view of its depth. The deeper will be the foundation, the better, because before it will be poured concrete, will be laid to pillow made of several layers of sand and crushed stone screenings.

Before proceeding to the excavation is necessary to prepare various tools that may be needed here. Depending on the type of soil in your area, you may need the following tools:

  • Bayonet spade.
  • Shovel.
  • A pick or a pick.
  • Ax.

In addition, prepare gloves so as not to rub the hands of the shovel, and you're ready. All land has to be dug into the fold of the foundation, except with tselnozalivnym goal. Dig better in dry weather, and try to do at once smooth and neat trench or pit. If possible, it is better to set the formwork to deepen dug not crumbled.

Installing formwork

No matter what kind of foundation you choose will need to install a wooden formwork. Only this rule would be the installation of concrete piles - they can be installed directly into a hole and pour concrete. But if you choose, for example, belt method, you'll need to buy boards and nails to create the shuttering boards. If you have a strong old board on the site, for these works they may well be used.

Formwork should be made smooth and orderly
Formwork should be made smooth and orderly

You need to put together panels of such a width that they went to the full depth of the trench, and towered over her at a sufficient distance. For this purpose it is necessary to calculate the width of you next way:

By the depth of the trench or pit add 25-30 cm - get about 60-70 cm.

This width is sufficient to obtain reliable and high-quality foundation that is suitable for any bath. Better just to make such an option, because in the process of building, you may want to add to the bath of the second floor and attic, and the basement will stand such a load. After the boards are ready they should be neatly installed in the trench and fix the special wooden bars between them to shields stood perfectly straight. When laying need to make sure that there was no large gaps in the structure.

The more accurate will be your foundation, the better will be the whole structure
The more accurate will be your foundation, the better will be the whole structure

Reinforcement and concrete

After the formwork will be finished so it is necessary to go to the step of laying reinforcement. Around the perimeter of the casing, or in every single hole under the piles must be laid armature. That the valve is to fulfill its function it is necessary to lay a special way. Reinforcement rods linked together by four pieces to get square design. If the valve is placed in the trench, then put them horizontally, and in the pit under the pile - vertically.

To proceed to the final stage, that is, the concrete is poured a solution it is necessary to dedicate a warm and dry day. Embarking on this work should be in the early morning, as the need to pour the foundation for one day - to share this work can not be categorically. Concrete solution can be ordered and delivered to you in a special vehicle of so-called "pear". Such vehicles equipped with a special sleeve, from which the concrete mortar is easily distributed over the formwork. This option takes a minimum of time and physical effort requires almost no.

Pour the foundation under the bath should be for one day
Pour the foundation under the bath should be for one day

If you have decided on their own to knead the solution, it is best to use the domestic concrete mixer. Portions to make a mixture and pour it evenly around the perimeter. possible to create a good solution for the foundation of the following formula:

1 bucket of water + 2 + 1 sand buckets dropout bucket bucket cement + 1 = approximately 1 cubic meter of concrete.

When filling must take place ( "poke") strong stick poured concrete, that there are no air bubbles. Once the whole perimeter of the upper layer will be filled must be carefully leveled to obtain a smooth and neat design.
