Previously, as a foundation for the steam room were stones covered with clay, which are put up on the log structure.Today, there are many methods of manufacturing bases to act as a reliable and durable support for any design.The foundations under the bath must meet certain requirements: be durable, safe, protect the walls from moisture and take on the weight of the structure.That is why the question of what is best foundation for a bath requires a responsible approach and taking into account some important nuances.

What should be the ground?
Equipping the foundation for a bath with his hands in the first place should pay attention to the peculiarities of the soil.For some reason, on this point often overlooked, but in fact it depends on
- not slump or sag;
- not swell;
- have good compressibility and flawless bearing capacity.
is not recommended to build bathhouse, where a large percentage of the composition of the earth takes peat, silt, fine sand.If another more suitable place for a bath there, then it is obligatory formation of coarse sand cushion.To do this, dig a hole for the foundation, put on the bottom of coarse sand, pour water and compacted.
ideal conditions - a dense, dry and homogeneous soil.When the surrounding natural component of the ideal does not hold and is characterized by high humidity and heterogeneity of structure, the depth of the substrate must be at least half a meter.Reflecting on the problem of how best foundation for a bath, it is equally important to know how deep the ground freezes.The base is laid at 20 cm below the known indicators, and the area around is filled with sand or gravel.Experts strongly advise before backfilling the foundation to handle engine oil or garden pitch (can be easily found in the construction department of any supermarket).
Regardless of what type of foundation for a bath you choose, the next mandatory step - counting.The platform must be leveled, remove the top layer of soil.Marked out a place for the foundation, note that the width of the substrate must be 10 cm greater than the width of the wall.
- four peg 50 cm long;
- right triangle with legs of 30 and 60 cm.
Spacing starting from the inner corner.We are trying to drive a peg into the alleged place of the first corner.We put on a triangle and calculate the sides of the center lines of longitudinal and transverse walls (mark the pegs).Then transfer the triangle to the opposite side and after determining the last peg trying to drive the axes.
To control layout made compare the diagonal in a rectangle.The difference should not be more than 2 cm. Then set castoffs.Rags - columns with nailed planks, which are located at a distance of 1 meter from the stakes.Boards nailed to the floor or bath at a height of 1.5 meters from the ground.
But that does not stop counting.We transfer the axial dimensions of the foundation of our plan to the upper edge of the castoffs.The rags are hammering nails and pull a cord so that it passes over the pegs hammered.
How to make a foundation for a bath
After the counting is finished, you can begin to build the foundation for a bath with his hands.But in order to decide on the follow-up action, you must select the type of substrate.Consider the popular types of foundations for the bath and especially their arrangement.
This foundation is expedient, if the land is in the area garden, forest or liquefied swamp.In fact, the strip foundation for a bath with his hands - a strip of concrete poured.
Roy pit, which is filled with sand to 20 cm. Moistens the first layer of the water and seals it.The second layer - the rubble, filled with cement-sand mortar, the third - sand.It should change the layers of gravel and sand several times.As a result, the depth of the foundations - 1 meter, and on unstable clay soil even more.
Puts formwork.Set the framework of reinforcement and concrete is poured into it.Construction finished putting some steam insulation (roofing material).For protection of surface water and rain make of fat clay and gravel sloped blind area width of 1 meter.
Strip foundation resistant to the effects of precipitation, therefore requires a complex system of drainage, drainage, horizontal and vertical waterproofing.
pier foundation is not suitable for non-cohesive soils, but good for the soil with a high content of clay, loam, gravel, coarse sand.
such a foundation with his hands under the bath is built by mounting pillars made of brick, concrete or rubble concrete, which is located at an interval of 2 meters.It is important to provide a vertical position, because the raw materials poor resistance to tension.Dimensions of the pillars of concrete and brick - 51h51 cm, rubble concrete - 60x60 cm.
Note dig poles to a depth exceeding soil freezing mark (usually more than 30 cm).Between them spread brick walls, waterproofing and paving (roofing felt, bitumen).
Red slit and calcium silicate bricks for the pier foundation is not suitable.To protect the subfloor from moisture and dust and heat preservation is made zabirka (wall connecting the pillars of concrete, brick or rubble stone).
not know how to pour the foundation for a bath, especially if the soil is a problem?Bored foundation will be a worthy release of their situation.It is kind of a columnar base, but the support have a circular cross section.On difficult ground to support the structure affects the weight, discontinuous shear forces occurring during the freezing winter of the earth's surface.
advantages of this type of foundation are obvious, but accurately determine the number of piles and the depth of their installation is difficult.In addition to drilling wells need special equipment - augers, arrangement bored foundation so are best left to the professionals.
If the soil in the area is not very good, and the call of masters with his special equipment for one reason or another is not possible, then a good alternative would be the pile foundation.The main advantage - simplicity and minimal construction time, regardless of the type of soil.While filling in the spaces between the pillars would require some effort, if the desire to overcome the difficulties encountered no trouble.
or screw piles driven into the ground, and the top combine beams.The distance between the auxiliary and the main pillar - about 2 meters.
main pillars made of bricks.Sometimes used concrete, crushed stone, asbestos cement pipes.The cross section of the main pillars - 51h51 cm subsidiary - 38h25 cm.
After installing the pit is filled halfway with sand, moistened and tamped layers.Between the pillars erected a brick wall thickness.The design is raised to ground level, align with cement and covered with roofing material.
Now you know how to make a foundation for a bath, depending on the characteristics of the soil, which means that the theoretical basis for future construction you already have.It remains only to make a choice and to begin to translate theory into practice!
