摘要：
FIELD: construction.SUBSTANCE: invention relates to hydraulic engineering construction and can be used in repairing various damages of concrete lining for long-term working channels of irrigation and drainage systems. Method of repair and sealing of damages includes filling the defective area of large damages with a width b≥0.05 m with gravel-crushed stone material 4, fixing its surface with liquid waterproof composition 5 based on liquid polyethylene and bentonite, and for sealing small damages 6 with a width b≤0.05 m – pressure injection of the polybentonite composition through tubular injectors 7 installed in damages. At the same time, the liquid polybentonite composition used to seal small damages 6 is made in the following ratio of components, mass. %: liquid polyethylene 60, bentonite 30, antifriction additives 10.EFFECT: advantage of the claimed invention is the possibility of repairing and sealing various damages of concrete channel liners, regardless of their dimensions, improving reliability,
