Когда у фундамента снижаются прочностные characteristics, it certainly affects the entire structure. Destructive processes occur throughout the entire structure of a building and, as it progresses, can eventually lead to its complete destruction. Reconstruction of the foundation with screw piles is one of the most effective methods for restoring the integrity of low-rise buildings. The use of this technology allows you to quickly and accurately restore any type of foundation bases.
Causes of the destruction of the foundation
The main factors causing subsidencefoundation, there are various changes in the lower layers of the soil. These processes are physico-mechanical and hydrological. Land, for example, can subside due to groundwater effects, construction work carried out nearby using heavy machinery, etc. At the same time, not only the old but also the new foundation can suffer.
The sunk soil “pulls” the foundation, inas a result, deformation processes are launched. The first sign of its subsidence are crevices in the blind area. Destructive processes begin at the base of the bedding foundation. If there is no immediate reconstruction of the foundation with screw piles, then the bearing characteristics and stability of the building will decrease, which ultimately will lead to its partial or complete collapse.
Selection of screw piles
When the foundation is being renovatedscrew piles, flaws, unfortunately, can also occur. The main problem, due to which the durability of the structure is reduced, is the susceptibility of the metal to corrosion. In this regard, the issue of choice of material should be given special attention.
Quality steel piles manufactured instrict compliance with technological requirements, necessarily have a corrosion-resistant coating, which includes epoxy resin and enamel. And the best material for the production of piles is galvanized iron. Renovation of the foundation with high-quality screw piles can extend the “life” of a house by 100 years!
The number and size of piles is selected taking into account the type of soil, the depth of freezing and the proposed mass load.
Foundation repair technology
- The study of soil features.
- Test screwing one pile into the ground.
- Screwing piles along the entire perimeter of the building (the distance from the walls is 20-25 cm).
- Filling the cavity of the pile cement-sand mixture.
- Welding of tips, installation of construction from channels and I-beams by welding.
- Raising the house with the help of special powerful jacks.
- Mounting piping new foundation.
- Lowering the house on the finished foundation.
The foundation is reconstructed most quickly and simply with screw piles on buildings up to 6x6 meters. For carrying out a full complex of works only 2-3 days are required
Repair of the foundation of large brickor wooden structures are more complicated, as it requires the installation of auxiliary piles under the center of the building. For this operation requires partial disassembly of the floor. However, regardless of the complexity of the task, the most effective and inexpensive method is still considered the reconstruction of the foundation with screw piles. Reviews of a huge number of customers who have decided to “reanimate” their real estate with the help of this technology are evidence of this.
Technology advantages
According to users, the indisputable advantages of the method of restoring the foundation using screw piles can be safely attributed:
- No need for large scale earthworks.
- Simplicity and efficiency of installation.
- The ability to provide the necessary strength and carrying capacity of any type of foundation.
- The durability of the structure (subject to the use of high-quality screw piles).
- The possibility of repairing the foundation on various types of soil and in any period of the year.
- Reasonable cost of work and materials.
