Set of 15x25 mm bentonite cord 40 m.p. + 40 m.p. fastening mesh for waterproofing construction joints

Bentonite cord 20x30 mm for waterproofing and sealing of working seams

Bentonite cord "Gidrostop" 20x30 mm  is made of sodium bentonite, swelling under the influence of water. Bentonite is a natural clay mineral, which swells and increases its size when in contact with water. In a closed space, it creates tension, reducing water permeability, even in the presence of cracks and porous places in concrete. Due to this, it is the optimal material for reliable waterproofing of concrete structures. Excellent technological indicators and simple installation method make it possible to use the product as an insulating material for joints in underground construction, hydraulic structures and in civil engineering.

• designed for waterproofing joints or eliminating leaks in concrete structures (basements, swimming pools, places where pipes are connected, sewer systems, etc.), forming a flexible and elastic gasket or flexible seal in a joint or crack;
• performs waterproofing of temporary window openings in non-residential basements, ventilation openings,
• It is used in all repair and reconstruction work on buildings and structures (in all cases when concreting is performed and when waterproofing of seams and joints is required). 
• It is used in water and sewer crossings, underground parts of construction sites, as well as in houses and buildings built below the groundwater level.

• low cost
• ease of installation (does not require highly qualified installers or special tools)
• wide range of operating temperatures without loss of properties -30°C to 50°C.
• installation on a damp base is possible
• plastic
• withstands hydrostatic pressure up to 7 atmospheres.
