Unfortunately, the formation of cracks in the floor and walls of private houses is not a rare phenomenon. Most often, such deformations occur due to subsidence of the foundations of buildings, which can be provoked by weakening of the foundation soil. It is possible to restore a house with damage of this nature using the Premium Technologies geopolymer injection technology.
Despite the fact that the house seems to us to be a solid structure, its position in space can dynamically change due to changes in the characteristics of the soil on which the house is built. The fact is that the foundation of the house, and therefore the entire structure, can be subject to uniform settlement or uneven settlement, when for one reason or another the settlement in adjacent areas of the foundation is different.
When the degree of settlement of the foundation exceeds the limit value, the load-bearing and non-load-bearing structures of the building are damaged. This is manifested in the formation of cracks in the floor and walls, the departure of load-bearing walls from the ceilings, the skew of doorways and window structures, and so on.
There can be several reasons for such subsidence of the foundation. These are both design errors and poor-quality construction work on compacting the soil of the foundation base. Force majeure situations are also possible, when the soil of the foundation is weakened due to a violation of the integrity of the underground water supply or sewage system or a sudden increase in the groundwater level. In any case, to prevent further destruction of the house and to eliminate cracks in the walls, it is necessary to strengthen the soil and raise the foundation of the house to the desired level.
METHODS OF SOIL STRENGTHENING AND FOUNDATION RAISING
The traditional method of strengthening the soil of the base and raising the foundation of the building involves the implementation of large-scale work. In this case, to eliminate cracks in the floor and walls, it is necessary to involve serious construction equipment. In this case, the full period of repairing the foundation, strengthening the soil and restoring the floor and walls of the house can take about 4-6 weeks.
Modern methods of soil strengthening, stabilization and lifting of foundations of private houses, which involve the introduction of a base of multi-component geopolymer resins Premium Technologies into the soil, are able to solve such problems within just 2-3 days. At the same time, there is no need to carry out earthworks and involve heavy special equipment.
GEOPOLYMERS INJECTION
To eliminate cracks in walls and floors using Premium Technologies technology, geopolymer injections are made either to a considerable depth under the foundation base (Deep Lifting technology) or directly under the concrete floor slabs (Floor Lifting technology). The expansion of the geopolymer material gains strength in 15 minutes, which allows you to quickly fill the voids in the soil under the foundation and increase the density and bearing capacity of the base soil. It is very important that the structure of geopolymers makes it possible to carry out injections, including in excessively moist soils.
During the injection process, Premium Technologies specialists are able to track the movement of concrete floor slabs and foundations in real time with an accuracy of ± 1 mm. Cracks are eliminated literally before our eyes. The injection procedure itself consists of drilling small holes or holes in the concrete floor. The diameter of the injection holes is usually 8-16 mm.
