Belt-pile foundation for your home: worth doing or not?

Alas, not every land plot hasideal conditions for the construction of the structure: a horizontal platform, reliable soil, lack of groundwater, etc. Therefore, very often the developer faces the need to strengthen the construction of the base, and instead of the usual tape,

pile foundation.

Why not a simple foundation?

When, instead of the usual ribbon foundationused combined? First of all, when the bearing capacity of the ground leaves much to be desired. The most reliable are rocky rocks, gravelly soils, dry sands and dry, hardened and compacted clays. Inferior to them in reliability raw fine-sandy with impurities soil and moist clay. In the category of dangerous fall fine and dusty sand, water-saturated clay, sandy loam, as well as loose soils - here it is simply necessary to use a belt-pile foundation.

Another option is when an enhancedbase - the location of groundwater is too high, if they also can not be diverted by drainage. And, of course, if you are planning to build not a private small house, but a multi-storey one, then obviously you can not do with a simple, shallow or even buried foundation: it is necessary to install more solid base constructions. Also, do not forget that the topography of the construction site requires special attention: if your site is located on a slope and level it for some reason

unprofitable, it is possible to use a belt-pile foundation.

Base calculations

Everyone understands that the construction of any housebegins with a foundation. However, in order for the building not to fall and not to sag, it is necessary to calculate the tape pile foundation, which will result in the base parameters: diameter of the reinforcement, width and thickness of the concrete. It is also necessary to determine the number of piles necessary for a particular building, their location and the distance between them.

Foundation installation

Knowing all the parameters of the future foundation, you canto start working directly on the construction site. The first stage is the release of the site from the existing networks on it - electricity, gas, water. It is also necessary to install a drainage system if groundwater is located in the ground, which can damage the structure being erected. Now the vegetative and most fertile soil layer is removed; Upon completion of construction, this land is used for planting the site. When the soil is prepared, under the belt-pile foundation a trench is pulled out and wells under piles are drilled in accordance with the calculations.

Next, waterproofing piles, installationreinforcement and pouring concrete. After the piles are ready, it is necessary to create a grillage, thus giving the structure additional rigidity. Before you start installing the tape foundation on grillage, the aboveground part of the foundation - the tops of the pile and grillage - are insulated.

As for the cost, then, when it comes topile-tape foundation, the price is an order of magnitude higher than in the case of an ordinary, non-reinforced foundation. However, it is difficult to argue with the fact that such a design is much more reliable, and this fact is a weighty argument in favor of a more expensive foundation.
