To ensure the waterproofness of working seams in building structures
Waterproofing bentonite cord "Hydrostop RED" 15x25 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" 15x25mm 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 15x25 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" 15x25mm 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.

Bentonite cord "Gidrostop RED" 15x25 mm is an important material for ensuring tightness and protecting building structures from moisture. Here are the basic steps for its installation and installation:
Surface Preparation : The surface on which the cord will be laid must be clean, dry and free of dust, dirt or other contaminants.
Measuring and cutting: Measure the length of the seam you want to fill. Cut the appropriate length of bentonite cord to spare.
Laying the Cord: Place the bentonite cord inside the seam or corresponding space, making sure it fits snugly against the walls of the seam or hole.
Fixation: To ensure better fixation and bonding to the concrete, use steel nails or other suitable fasteners. Install them every 30-40 cm along the seam or as needed.
Checking continuity : It is important to ensure that the cord is not in continuity in the seam. Ensure that the cord is laid without gaps or overlaps to ensure continuous moisture protection.
Additional fixation (if necessary) : If required, use a special mesh, sealant or adhesive for additional fixation and sealing of the seam.
Checking the quality of installation: After installation is complete, check the quality of installation, making sure that the cord fits snugly to the surface and provides reliable insulation.
Correct installation of Hydrostop RED bentonite cord is important to ensure effective protection against moisture and maintain the integrity of the building structure. When performing work, you should follow the manufacturer's recommendations and use appropriate personal protective equipment.
What is the method of laying and installing bentonite cord?
Installation of a bentonite cord depends on its type and is done using a special mesh, sealant or glue. To achieve complete compaction and insulation from moisture, a bentonite strand "Hydrostop RED" in the form of a tape is installed in the cold seams of foundations and walls using steel nails every 30-40 cm to avoid displacement and to provide a better connection with the concrete. During installation, it is necessary to prevent disruption of the continuity of the tape position.
How to choose the right bentonite cord?
To seal 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.
