For sealing of places of passage of engineering communications
Waterproofing bentonite cord "Gidrostop RED" 5x20 mm is a material designed to ensure the waterproofness of working seams in building structures and in places of communication. When in contact with water, the bentonite cord significantly increases its volume. The resulting gel in a confined space creates a stress that reduces water permeability, even in the presence of cracks and porous places in the concrete. To achieve complete sealing and isolation from moisture, the bentonite cord "Hydrostop RED" 5x20mm in the form of a tape is mounted in the seams of foundations and walls with steel nails every 30-40 cm to avoid displacement and to achieve a better connection with concrete. When mounting, it is necessary to avoid breaking the continuity of the tape position. Excellent technological performance and an easy installation method make it possible to use the product as an insulating material for joints in underground construction, hydraulic structures and civil engineering. Bentonite cord "Hydrostop RED" has a cross-section of 5x20 mm, is made of bentonite clay and is a rectangular cross-section profile that swells when in contact with water. The cord increases in volume by 4 times, i.e. by 400%, while being in the concreted joints, it covers absolutely any cracks and holes. Bentonite cord securely and firmly adheres to the concrete surface, filling seams, junctions and the smallest voids in the concrete body, forming a reliable protective layer.

Scope of application:
Method of installation and installation:
Installation of bentonite cord depends on its type and is carried out using a special mesh, sealant or glue. To achieve complete sealing and isolation from moisture, the bentonite "Hydrostop RED" 5x20mm harness in the form of a tape is mounted in cold joints of foundations and walls with steel nails every 30-40 cm in order to avoid displacement and to achieve a better connection with concrete. When mounting, it is necessary to avoid breaking the continuity of the tape position.
