The foundation on screw piles is used whenconstruction of low-rise, private houses, capital and temporary economic buildings. The main advantages of such a foundation are: its reliability on any ground, including wetlands, independence from the climatic conditions of the region, in addition, such grounds do not need a flat area. All this attracts developers. So, we build the foundation with our own hands.
To build a screw foundation with your own hands,First of all, you need to understand what a screw pile is. It is a stainless steel pipe with a pointed tip, to which a blade is welded, resembling a propeller in appearance. The blade is screwed into the ground to the required depth. The depth of the pile depends directly on the type of structure for which the screw foundation is made by hand. A brick or wooden house, a bath or an economic unit requires different depths of screwing the pile into the ground, but in any case it can not be less than one and a half meters.
The foundation on such piles is not very complicated inconstruction and has several advantages over other types. These include low cost, long service life (over one hundred years), short (from one to two days) installation period, seismic resistance and, as mentioned above, the possibility of erecting on any soils and year-round. In addition, the screw foundation, built by oneself, assumes that after installation of the piles, it is possible to immediately begin further work on erecting the building, since it does not give a draft. The foundation on such piles is not without its drawbacks: it is the impossibility of the basement room equipment, the need to insulate the lower part of the building and the weight limitation of the erected building.
