With time, the house foundation loses its bearing capacity, which can lead to an emergency state of the building. Therefore, in the process of the house reconstruction and repair, special attention is paid to the foundation strengthening. GeoResin provides services associated with strengthening the old house foundation using innovative technologies of geopolymer injection.
When the foundation should be repaired
From the moment of erection, there are many destructive factors affecting the building foundation, both natural and anthropogenic.
Natural factors include:
- · groundwater level fluctuations;
- · soil suffusion;
- · seismic activity, etc.
Among the anthropogenic it is worth noting:
- · accidents of water communications;
- · loads on the building foundation beyond project basis;
- · low-quality building materials used in construction;
- · construction or earthwork operations nearby;
- · vibrations caused by construction machinery or heavy vehicles.
This gradually leads to the appearance of cracks in the foundation and walls, which in turn makes the building unusable. You can prevent such consequences by strengthening the building foundation in proper time.
When the old house foundation is repaired and strengthened:
- · during the new building construction on the foundation of a previously built, already destroyed house;
- · in the case when it is required to strengthen the base and increase its bearing capacity (when building up new floors, installing heavy equipment, etc.);
- · during subsidence and changes in the properties of the foundation soils;
- · when external signs of damage to the foundation appear (cracks, subsidence, signs of deformation of the external or internal finish, doorways distortions, etc.);
- · emergency condition of the building.
Any work on the foundation reconstruction always begins with its technical examination by a specialist. It allows you to find out what kind of design problems need to be solved in the repair process, and come up with a competent engineering solution.
Ways to strengthen the buildings foundations
Today, there are several methods of strengthening bases and foundations that will help protect your home or commercial premises from destruction. The most common of them are:
1. Injection method.
The injection technology is based on the use of polymer resins. This is one of the most effective and fastest ways to strengthen the house foundation without too much noise and dust. The technology comes to the polymer resins injection into the soil base or foundation, which, expanding, completely fill all the voids and displace water. Due to this, the base is compacted, its bearing capacity increases, the foundation returns to its original position. The technology can be implemented in various ways. GeoResin performs soil injection works under its own brand GeoResin Deep Stabilization and GeoResin Slab Lifting.
2. Cementation method
If the soil at the construction site does not meet the requirements, and the building must be erected on this site, then artificial foundations are fixed up. One of the ways to artificially strengthen the soil is cementing, which is carried out by injecting liquid cement mortar or cement milk into the soil through pipes, which, hardening in the soil pores, give it a rock-like structure.
3. Strengthening the house foundation using bored piles.
Bored piles are widely used to strengthen the foundation of a residential building. From the land surface and from the floor level of the first floor or basement, they drill vertically and obliquely, through the existing foundation of the borehole until it reaches the stiff soil. After drilling is completed, a rebar cage is lowered into the borehole and a cement mortar is served through the injection tubes. The resulting piles resemble the tree roots, most of the load is transferred on.
4. Strengthening with reinforced concrete holders.
This method is also most often used to strengthen the foundation. The principle of technology is to expand the base along the outer perimeter. The foundation is strengthened with a reinforcing mesh, formwork is installed, after which a concrete mixture is poured between the mesh and the formwork.
