FIELD: construction.
SUBSTANCE: method to eliminate water leaks in underground engineering utilities includes drilling of boreholes and injection of a strengthening hydraulic insulation composition into them. The strengthening hydraulic insulation composition is injected into previously drilled boreholes by means of separate supply of the following into the mixing nozzle under pressure of 0.2-1 MPa: a cement-water suspension with W/C=1-1.5 and liquid glass with density of 1.3-1.6 g/cm3 at the following ratio of specified mixtures accordingly, wt %: 75-90 and 10-25.
EFFECT: simplified technology of water leaks elimination in a defect hydraulically insulated zone of underground engineering utilities.
