The arrangement of foundations, as well as the strengthening of existing foundations using screw piles, due to the development of the technical base, is becoming increasingly accessible for use in private purposes.
This type of pile foundation is distinguished by its reasonable price and a visible effective result in the shortest possible time.
A screw pile is a pipe with blades, which is driven into the ground by the screwing method. 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 soil erosion by groundwater, natural shrinkage. The result is superior even to the expensive and technically complex complete replacement of the foundation. The highest stability of the supporting structure when using screw pile technology makes it possible to erect additional floors even in buildings that were in a state of emergency.
IN WHAT CASES IS SCREW PILES CURRENTLY USED?
The use of screw piles as a method of strengthening the foundation significantly expands the geography of construction work. On screw piles as a base, it is possible to erect metal and concrete structures with minimal excavation. Strengthening foundations on waterlogged, peaty, clay, sandy soils takes a minimum of time and labor, and the result often exceeds the wildest expectations.
In general, screw piles are one of the most popular and versatile ways to strengthen foundations and increase the bearing capacity of the entire structure being erected or already built on weak soils. A pile made in accordance with GOST is able to withstand the effects of weather, frost heaving forces and the effects of loads for a long time.
WHAT PROBLEMS CAN THE APPLICATION OF SCREW PILES HELP TO SOLV?
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 support on the ground. Unlike reinforced concrete foundations, a screw pile can withstand more than 20 tons of pressure. Piles can be used for the following purposes:
Increased bearing capacity of a multi-storey building. Partially or completely replacing an old foundation that is under constant pressure is impossible. In this case, piles can support the foundation without exposing the structure to unwanted external influences.
Strengthening old houses with weak foundations for the construction of superstructures.
Stabilization of the soil under structures due to excessive subsidence or skew.
A screw pile is screwed into deep hard layers of soil, thereby maintaining the stability of the building foundation in almost any conditions.
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 Premium Technologies Deep Lifting allows us to achieve high stability of the foundation in an even shorter time. The essence of the technology is the point introduction into the soil of a special geopolymer resin, which expands and fills all voids, removes excess water from the pores and raises the foundation to its previous level. In this case, there is no excavation work. Using the latest technology, the Premium Technologies company guarantees a quick and high-quality increase in the bearing capacity of soils, which allows us to strengthen an existing, even emergency, structure.
