The durability of the building depends on right choice of the base, however at construction of small constructions it is absolutely optional to be spent for solid basis under the building. In some cases it is possible to reduce significantly expenses if to be guided by several important points.
Before starting construction of giving, bath or other building demanding construction of the base it is necessary to know structure of the soil in which the building foundation and also dimensions, number of storeys of the house will be laid to have idea of loading. Proceeding from it, it is possible to select the most suitable construction material.
Sand and gravel
These are the most available materials for arrangement of the base. The structure of the base represents the ditch which is dug out on perimeter on which bottom the sand layer is filled. From above gravel, crushed stone or beaten brick is located. Sometimes this pie is filled in with cement solution. The similar basis under the building is relevant on not loose soil to construction of small constructions from tree: baths, country house, garage or other utility room. The main advantage of such base – the low cost of the used materials.
Mass concrete and foundation blocks
Here it is worth paying attention to couple of the moments: arrangement of timbering and armature. The timbering (especially at the exit from the earth) has to be rather strong: it is necessary to use boards not less than 30 mm thick, strengthening them vertical pegs through everyone half-meter. Fittings need to be installed both in horizontal position, and in vertical; at the same time bars connect among themselves to the help of lashing wire. Filling of mass concrete – labor-intensive process therefore availability of the concrete mixer in which it is more convenient to mix cement, sand, crushed stone and water is desirable. The main minus of mass concrete – labor input. The building basis can be built from foundation blocks in day, on condition of availability of ready trench. But works require the lifting equipment and to bring such material too will run into money. Some builders for construction of the base use hollow blocks which are filled with solution subsequently. The similar choice is connected with the smaller weight of material, the best heat conductivity that is important if it is going to build the basement, the first floor.
Quarrystone and butobeton
As quarrystone, inexpensive and available material, the good slabby stone or cobble-stone is used. The similar base is capable to maintain considerable loadings and well keeps within even on puchinisty soil. Separate stones communicate among themselves cement and sand solution. The best result can be achieved if base trench in which quarrystone is laid, to fill with solution of the cement mixed with small crushed stone (Klintsy). Some producers offer the ready blocks manufactured of mix of quarrystone and cement.
