The critical situation with the majority of hydraulic engineering structures (GTS) in the country requires immediate and large-scale actions. Decades of operation without proper maintenance and modernization have led to the fact that a significant part of dams, dams, reservoirs and other GTS have exhausted their design life and are in an emergency or near-emergency condition. The problem is compounded by a lack of funding, the difficulty of carrying out repairs at existing facilities, as well as the lack of effective and rapidly implemented technologies. Therefore, the relevance of the search for new, more efficient and economical technologies for repairing and strengthening GTS is beyond doubt. A promising direction in this area is the use of geotechnologies, and in particular, jet cementation.
