FIELD: construction.
SUBSTANCE: method for elimination of water leaks in underground engineering buildings includes drilling of holes and separate injection of reinforcing waterproofing solutions of cement-water slurry and liquid glass into them through the mixing nozzle under the pressure of 0.2-1.0 MPa. Cement-water slurry with W / C = 1.6-2.5, containing 5-10% from weight of amorphous silica fume cement, and 25-30% aqueous solution of liquid glass with density of 1.15-1.2 g/cm3 is used as reinforcing waterproofing solutions at the following ratio of the specified solutions respectively, wt %: 50-70 and 30-50.
EFFECT: provision of safe and long-term waterproofing of underground buildings, reduction of the materials consumption.
