Waterproofing bentonite cord "Hydrostop RED" 20x30 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" 20x30mm 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 ensure 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 20x30 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.

Method of laying 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" 20x30mm harness in the form of a tape is mounted in cold joints of foundations and walls with steel nails every 30-40 cm to avoid displacement and to ensure better connection with concrete. When mounting, it is necessary to avoid breaking the continuity of the tape position.

How to choose the right bentonite cord?

To seal the technological seams, the size of the bentonite cord is selected depending on the thickness of the concrete wall or slab and the technological characteristics of the structure.

  • for sealing holes – bentonite cord round cut with a diameter of 22 mm.
  • for the inputs of communications – a rectangular section of 5x20 mm.
  • for sealing cold joints – rectangular section 10x20; 15x25; 20x30 mm.
