What is needed is the Foundation for the house of aerated concrete? The only correct answer does not exist. Almost any of the possible, would be a great beginning for the type of construction. It is worth noting that the design bases for wooden or brick buildings, selected quickly, however new materials have their own standards and requirements.
In the design of Foundation under the house, many people make a fatal mistake – hoping that for the lightweight material, does not require massive Foundation. Strip Foundation under the house of aerated concrete must have costed a fortress and depth, otherwise in a short time, the design of the house cracks. The main task of the concrete substrate during construction is to create conditions under which all the pressure will disperse evenly without peak portions.

The major problem in the construction of support structures for the house of aerated concrete, is the force of buoyancy. This force balance of a building constructed of heavier materials. To solve the problem, you need to understand what width would be ideal. Concrete substrate under one-storey house of aerated concrete can be a low-depth, but you should pay great attention to exactly how it will be constructed.
It is worth noting that the most appropriate option is the design of the support piling under the house of aerated concrete as in the video:
The form of the house Foundation with additional piles, capable of holding from deformation framework built on almost any soil or ground. Thanks to the piles, the deepening which usually reaches 1 meter, give the load to the soil, and counteract the forces pushing.

In order to construct the Foundation with his own hands under the house of aerated concrete on two floors, it is necessary to consider all the important aspects of construction. Among all, the most important are:
- the mass of the walls and the pressure force on one meter of the base of the concrete;
- the mass of the slab, which will put additional pressure on the base of the construction;
- the weight of the roof as an additional weight.
In the construction of two-storey houses, the important question remains – what is the size of the Foundation under the house of light material is needed. Professional builders involved in the construction of such buildings, it is recommended to use a design that will be at least 10 centimeters wider than the building block at the top and 15-20 wider in the bottom part. Is this wedge-shaped design, makes it possible to prevent «sezzhanie» the house on the ground. Also, if you use this reason, you should pay your attention on a substrate, which is typically, is made entirely of sand.
In General, the calculation of foundations under the house of aerated concrete can be made using an ordinary calculator tape base under construction.

This type of base is characterized in that the pouring of concrete occurs directly under the entire surface of the structure. There are some positive sides and negative with this Foundation of the building. Among the positive, we can distinguish:
- easy to fill with a concrete mixture at the construction site;
- the use of a smaller quantity of rebar to strengthen the base;
- the Foundation, if desired, can serve as a great floors inside the houses are built;
- the mass distribution of the whole house on the stove reduces the buoyancy force acting on the house.
Among the negative aspects, the use of such the substrate include:
- the high cost of concrete for making concrete mixture;
- the need to align the larger surface horizontally, which is possible only by special equipment;
- to fill such a Foundation, you need to find smooth area or produce a large amount of earthworks to level the site under the fill;
- this type of Foundation requires long-term miscalculations of holding water, gas, and the utilization of valves;
- the need for careful selection of soil for the placement of such base design;
- prolonged drying of the surface in solid form fill will not allow the construction immediately after the organizational work.
Great attention should be paid directly to the characteristics of the soil under a future construction. The disadvantages of such a Foundation can be attributed to the shallow horizon: this high-rise building with no additional fortifications may «sail» after some time, due to caving of the soil. It is also a view of the potting base, not suitable for those regions where the depth of frost penetration is higher than the $ 1 m.
For direct calculation of the volume of concrete needed, you should use the geometric formula. As an example:
The height of our future Foundation will be 30 cm, width under the construction given the fact that the Foundation walls are larger than 10 cm – 620 cm, length of the structure, with the same account, is 1020 cm Translate all values to meters:
- 0,3;
- 6,2;
- 10,2.
Now all the figures obtained multiplied among themselves and get the volume of concrete we need to pour the Foundation. 0,3*6,2*10,2= of 18.97.
Given the fact that the concrete in drying loses part of the water we need about 19,2 cubic meters of a mixture of.
