Bentonite Grout Backfill Technology for Underground Structures

Abstract

Abstract The article presents the basic methods of the most effective durable solution for the restoration of underground waterproofing of the structures in use, which are in impossible conditions for the application of outdoor protection. New types of resistance to aggressive environments of mineral waterproofing are considered, along with the technological scheme for the work. In addition, organizational methods have been developed for hydro protection of building structures. This technology can be applied from the basement of buildings in operation and be implemented at any time of the year. The proposed modern materials and technological solutions for the protection of underground structures of buildings were confirmed by the authors using an analysis carried out using the mathematical apparatus. Creating protection of premises against leaks from the mineral composition allows to increase the durability of the building itself, to ensure the normal operation of equipment and monitoring devices of the stations, as well as comfortable conditions for staff. Technological maps for the device of a new type of filling waterproofing have been developed, allowing to carry out and monitor all technological processes for operations.
