Bentonite cord for waterproofing and sealing construction joints 5x20 mm, red color, 5 m.p.

Bentonite cord "Gidrostop" Sanpol 5x20 is made of sodium bentonite, which swells under the influence of water. Bentonite is a natural clay mineral that swells and increases in size when in contact with water. In a confined space, it creates tension, which reduces water permeability, even in the presence of cracks and porous areas in concrete. Due to this, it is an ideal material for reliable waterproofing of concrete structures. Excellent technological performance and simple installation method make it possible to use the product as an insulating material for joints in underground construction, hydraulic structures and civil engineering.

Application:

• intended for waterproofing joints or eliminating leaks in concrete structures (basements, swimming pools, pipe connections, sewage 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 during all repair and reconstruction works of buildings and structures (in all cases when concreting is carried out and when waterproofing of joints and joints is required). 
• used in water and sewer passages, underground parts of construction sites, as well as in houses and structures built below the groundwater level.

Advantages:

• low cost
• easy installation (does not require highly qualified installers and special tools)
• wide range of operating temperatures without loss of properties - 30 °C to 50 °C.
• installation on wet substrates possible
• plasticity
• withstands hydrostatic pressure up to 7 atmospheres.
