LIFTING AND STRENGTHENING OF FOUNDATIONS OF INDUSTRIAL FACILITIES

Geopolymer resins have found their application in the field of repair and reconstruction of industrial and industrial enterprises. Geopolymers can be used both to strengthen the foundation of operating facilities, and when upgrading premises for the installation of more powerful equipment.

Industrial buildings during operation are often subjected to excessive loads. This can be both static loads caused by the features of mechanical production, and continuous dynamic effects and vibrations caused by the course of the production process.

Such loads can lead to soil compaction under the foundation and floor of the lower floor of the structure, as well as to subsidence of certain sections of the foundation under the influence of production mechanisms. You can correct the situation and eliminate the cause of subsidence of the foundation by injecting Uretek geopolymer resins into the ground.

Strengthening the foundations of operating enterprises

Work on the injection of geopolymers is carried out quickly and with minimal interference to the production process. For injection, compact mobile units are used that inject geopolymer material through holes in the floor of the lower floor or in the coating (soil) around the perimeter of the building. The process of introducing geopolymers is made through pipes of small diameter. Hardening of the resins and increase in the bearing capacity of the foundation occurs in a matter of minutes.

It is also important that the use of geopolymers to strengthen sections of the foundation and foundation soil, which are subjected to excessive dynamic loads, is very effective. The fact is that these materials have the property of elasticity and are able to restore their volume after the completion of excessive dynamic effects.

Modernization of industrial facilities

Reconstruction of old industrial structures often implies the need to increase the limit of permissible loads on the foundation and floor of the lower floor of the building. This must be done while increasing production capacities, target reorientation of the premises, increasing the turnover of the enterprise, etc. After all, often the installation of more powerful equipment involves a stronger effect on the soil under the foundation.

If the room is not designed for such a load, the soil under the foundation can also be strengthened using the Deep Injection method. To do this, according to a similar scheme, the geopolymers are injected into the base soil to a considerable depth, which leads to the strengthening of the foundation of the entire structure. Injection is performed until the soil has acquired the necessary indicators of bearing capacity.
