Choosing type of the base for the house from gas-blocks it is necessary to consider feature of this construction material. Such construction more others needs the reliable steady basis.
Instruction
1. The gas concrete, unlike other construction materials, possesses one, but essential shortcoming: he is very susceptible to any sort to deformations. The firmness on bend at blocks from gas-silicate is so small that even small motions of the base can cause emergence of cracks of all wall. Therefore starting construction of such house the main attention needs to be paid it to the basis.
2. Requirements to the base for the house from gazoblokauchityvy features of this material, the choice of types of the bases is significantly limited here. For constructions from gas-silicate the steadiest and well reinforced bases are required. To it belong: monolithic plate, tape and column bases. It is extremely important to make the correct calculation of bearing capacity and durability of the base for houses of gas-blocks with the first floor or the high basement.
3. Build the qualitative base for such constructions not easy, but business can become complicated considerably if on the construction site high level of underground water. For the builder in this case there are two exits: or to build the house of other material, or to mount drainage communications. In the latter case expenses on construction of housing will significantly increase.
4. The high level of underground water is dangerous by overwetting of the soil and risk of frequent floodings in spring - autumn the periods. All this is fraught with premature destruction of the base and, respectively, deformation of the basis and the house. Damp soil carries to discharge silnopuchinisty, in what the base is powerfully affected by various forces: pushing out, compression, expansion and other. Therefore for construction of the house from gas-blocks on puchinisty soil it is required to waterproof qualitatively the basis and to make ring or wall drainage.
5. The optimum base for the house from gazoblokovdlya small-sized constructions will be rather monolithic tape basis. It is not recommended to build buildings of gas-silicate on the combined bases. Level of deepening of tape is calculated proceeding from type of soil and other factors of construction site. Also the pile base will be suitable for such designs. But it needs to be clasped with integral frame of reinforced concrete grillage. This precaution will allow to prevent cracking of gas-concrete walls.
6. The monolithic reinforced concrete slab – more expensive basis, but it is much more reliable. On such base the construction from gas-silicate blocks can stay long decades without any damages. This solution is optimal for the individual builder.
