FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering construction and can be used for sealing and repairing joints of concrete channel linings, reservoirs, and also as keyways of water supply facilities. Deformation seam of a concrete cladding includes a sealing element, made in the form of an elastic container (bundle) with a filler placed in it from the expanding material. Sealing element is mounted in the holes made on each side of the concrete lining. At the same time, additional containers of geotextile material filled with bentonite are placed under the sealing elements.
EFFECT: application of the invention will make it possible to exclude water losses for filtration, to increase the durability and quality of sealing of butt joints of anti-filtration liners from concrete (reinforced concrete) slabs.
