SCREW PILES - A POPULAR VIEW OF PILED FOUNDATIONS
The construction of foundations, as well as the strengthening of existing foundations using screw piles, thanks to the development of the technical base, is becoming increasingly accessible for private use.
This type of pile foundations is notable for its reasonable price and obvious effective result in the shortest possible time.
A screw pile is a pipe with blades, which is buried in the soil by screwing. The use of piles significantly increases the strength and stability of the base of the building structure. Such a foundation is characterized by high resistance to undermining by groundwater, natural shrinkage. The result is even superior to the costly and technically sophisticated complete foundation replacement. The highest stability of the supporting structure, provided that the technology of screw piles is applied, makes it possible to erect additional floors even in buildings that were in disrepair.
In what cases is the use of screw piles relevant?
The use of screw piles as a way to strengthen the foundation significantly expands the geography of construction work. On screw piles, the construction of metal and concrete structures with a minimum amount of excavation is possible as a basis. Strengthening foundations on flooded, peat, clay, sandy soils takes a minimum amount of time and labor, and the result often exceeds the wildest expectations.
In general, screw piles are one of the most popular and universal ways to strengthen foundations and increase the bearing capacity of the entire structure being built or already built on soft soils. A pile made in accordance with GOST is able to withstand the effects of weather, frost forces and loads for a long time.
What problems helps to solve the use of screw piles?
The key task of screw piles is to strengthen the supporting structure in problem areas with low soil density. The unique design with wide blades at the base of the pile increases the actual area of вЂ‹вЂ‹support on the ground. Unlike reinforced concrete foundations, a screw pile can withstand more than 20 tons of pressure. Piles can be used for such purposes:
- Strengthening the bearing capacity of a multi-storey building. It is impossible to partially or completely replace an old foundation under constant pressure. In this case, the piles can support the base without exposing the structure to undesirable external influences.
- Strengthening old houses with flimsy foundations for the construction of add-ons.
- Stabilization of the soil under structures due to excessive subsidence or skew.
A screw pile is screwed into the deep hard layers of the soil, due to which it maintains the stability of the base of the building under almost any conditions.
A modern alternative to screw piles
Despite the high efficiency of using screw piles, more advanced and effective methods have now appeared that allow solving the problem of high-quality construction in the opposite way - not to strengthen the foundation, but to stabilize the soil. The unique technique of our company Uretek deep injection allows us to achieve high stability of the base even in a shorter time. The essence of the technology is the precise introduction into the soil of a special expanding geopolymer resin, which fills all the voids, removes excess water from the pores and raises the foundation to the previous level. At the same time, there are no earthworks. Using the latest technology, URETEK guarantees a quick and high-quality increase in the bearing capacity of soils, which makes it possible to strengthen an existing, even emergency building.
