When planning the construction of any structure, you should always pay special attention to the soil. Sandy soil is well suited for these purposes, which is also not inferior to his sandy fellow. On such soil, the layers are located horizontally. And a completely different matter is the marshy soil on which to build something is much more difficult, since its layers are mixed. In addition, they differ in different porosity, as well as a high water content. Not so long ago, the circumstances listed were a serious obstacle to the construction of the foundation in the swamp. Because even the load for such a foundation was not possible to calculate. Another feature of marshy soil is that in winter it rises, and when the melting of ice begins, it lowers.

However, in connection with the accelerating rate of construction, there was a need to use marshy areas. Screw piles successfully decide the difficulties accompanying construction in marsh lines. It should be noted that even the most marshy soil contains solid layers, and you can find them through geodetic research. The fact is that the screw piles have different lengths, thanks to which these hard layers can be reached. In addition, piles are extensible even during the installation process. To fix the piles, a metal frame is used in combination with slabs or beams. Increased strength is achieved by concreting.
