Foundation subsidence, which often manifests itself in the form of deformation and subsidence of individual sections of the first floor floor, often leads to cracks in the floor and walls. Dangerous damage to buildings can be avoided as soon as possible by strengthening the base soil and stabilizing the foundation using Premium Technologies techniques.
The reasons for the weakening of the foundation soil and the gradual subsidence of the foundation of a private house can be different. Most often, such problems arise due to loosening or poor-quality preparation of the soil under the foundation. It is also possible to simply ignore the need to conduct survey and geodetic work during construction, as well as weakening of the soil and further subsidence of the foundation due to a breakthrough of a water supply or sewage system, the action of groundwater, the destruction of underground tanks, and so on.
If the situation becomes more complicated and the degree of subsidence of the foundation increases, gradual damage to the supporting and non-supporting structures of the building, skewing of windows and doorways, disruption of thermal insulation and, as a result, the slow destruction of the entire house is possible. In order to stop subsidence and stabilize the foundation, it is necessary to urgently strengthen the foundation soil, and then lift and stabilize the foundation, and at the final stage – leveling and restoring the floor.
FOUNDATION AND FLOOR RAISING
Thanks to the application of the Deep Lifting geopolymer injection technique, the foundations of private and multi-storey buildings can be lifted without any destruction. The fact is that for the injection of Premium Technologies geopolymer resins, there is no need to involve massive equipment for earthmoving or concrete work.
Deep injection of Premium Technologies geopolymers makes it possible to strengthen soils and increase their bearing capacity. As a result of injection to a depth of up to 10 m, the foundation is raised to the desired level with an accuracy of ± 1 mm. The work is monitored using high-precision laser levels in real time. The maximum height of the foundation is raised to 20 cm. In this case, the injection is carried out directly under the foundation sole.
In some cases, after the completion of operations to strengthen the base soil and raise the foundation, the first floor floor slabs are leveled. Here, the restoration is carried out using Floor Lifting technology: geopolymers are injected directly under the concrete base slab. For this, holes with a diameter of 8-16 mm must be drilled in the slab, which are simply closed after the work is completed.
ADVANTAGES OF THE Premium Technologies METHOD
The structure of Premium Technologies geopolymer resins allows you to perform foundation lifting and floor slab leveling work at any time of the year and in any weather, day or night. At the same time, thanks to the mobility and compactness of the equipment used, the work is carried out without the relocation of residents.
The material used for lifting the foundation and floor slabs is environmentally friendly, stable for a long time, harmless to plants, animals and people. It does not pollute the soil and the environment, does not react with water and has waterproofing properties.
Due to the fact that geopolymer resins gain strength just 15 minutes after injection, foundation stabilization and floor slab lifting in private homes can be completed in an average of 2-3 days. At the same time, cost savings compared to traditional technologies reach 25%.
