The foundation on screw piles is used in the construction of low-rise, private houses, capital and temporary outbuildings. The main advantages of such a foundation are: its reliability on any soil, including marshy, independence from the climatic conditions of the region, in addition, such foundations do not need a flat area. All this attracts developers. So, we build the foundation with our own hands.
What is the foundation on stiltsTo build a screw foundation with your own hands, you first need to understand what a screw pile is. This is a stainless steel pipe with a pointed tip to which a blade is welded, in appearance resembling a propeller. The blade is screwed into the ground to the required depth. The depth of the pile depends on the type of structure for which a screw foundation is made with your own hands. A brick or wooden house, a bathhouse or a utility block require different depths of screwing the piles into the ground, but in any case it cannot be less than one and a half meters.
If a firm decision is made that you will build the foundation on piles with your own hands, then several people will need help to work. Piles are screwed in by rotating them to the required depth. It must be taken into account that if at this moment stones, tree roots or something else interfering with the process come across the pile, it is necessary to unscrew the pile, clear the place and only then continue work. After screwing the piles on top, special head plates are welded onto which the load from the building will be distributed.
The piles themselves (to give rigidity to the whole structure) are connected by a wooden beam or a metal channel. When the required depth is reached, the pile, thanks to the blades, is firmly and firmly fixed in the ground. When building a screw foundation with your own hands, you need to remember that the quality of piles plays a key role. In this case, the quality of the metal, the location of the blades (they should not be symmetrical) and their manufacturing technology are also important.
The foundation on such piles is not very complicated in construction and has a number of advantages compared to other types. These include low cost, long service life (over one hundred years), short (from one to two days) installation time, earthquake resistance and, as mentioned above, the possibility of construction on any soil and year-round. In addition, the self-built screw foundation, suggests that after installing the piles, you can immediately begin further work on the construction of the building, since it does not precipitate. The foundation on such piles is not without drawbacks: it is the impossibility of equipping the basement, the need for insulation of the lower part of the building and the weight limit of the erected building.
If the screw piles are selected correctly, and the installation process is not broken, you will get a reliable and solid foundation that will withstand the structure and last for many years.
