Bentonite cord 10x20 mm for waterproofing and sealing working joints, 5 r.m. Sanpol
Bentonite cord "Hydrostop" SANPOL 10x20 securely and firmly adheres to the concrete surface, filling seams, abutment and the slightest voids in the concrete body, forming a reliable protective layer. The principle of operation is that as a result of hydration, the bentonite cord increases in volume, forming a gel-like mass that fills all cracks and voids and reliably seals the seams of the concrete structure. The cord expands 4 times in the concrete body.
- concreting interruption seams: cold, working seam
- inputs of engineering communications
When interacting with water, bentonite bundles uniformly increase in volume by more than 4 times, providing reliable bentonite waterproofing without losing structural strength. Due to the composition, the Hydrostop harness retains flexibility even at low temperatures (up to -15 ° C). Bentonite bundles are resistant to chemical compounds, such as, for example, freshly laid concrete.
Sold in bays of 5 m.p.
Bentonite cord "Hydrostop" SANPOL 10x20 mm is made from sodium bentonite, which swells under the influence of water. Bentonite is a natural clay mineral that, upon contact with water, swells and increases its size. In a confined space, it creates a stress that reduces water permeability, even in the presence of cracks and porous places in concrete. Due to this, it is an ideal material for reliable waterproofing of concrete structures. 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.
Application:designed for waterproofing joints or eliminating leaks in concrete structures (basements, swimming pools, places of interface with pipes, sewer systems, etc.), forming a flexible and elastic gasket or a flexible seal in a seam or crack;
- performs waterproofing of temporary openings of windows of non-residential basements, ventilation openings,
- it is used in all works on repair and reconstruction of buildings and structures (in all cases when concreting is carried out and when waterproofing of joints and interfaces is required).
- it is used in water and sewer crossings, 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 operating temperature range without loss of properties -30°C to 50 °C.
- installation on a wet base is possible
- plasticity
- withstands hydrostatic effects up to 7 atmospheres.

How to install bentonite cord?
- The bentonite cord of the round cut d22 is inserted into the hole after the coupling screw and covered with a repair mixture.
- Bentonite cord 5x20 mm rectangular cut for the inputs of communications – wrapped around the pipe, fixed with a sealant or wire and filled with a repair mixture.
- Bentonite cord 10x20; 15x25; 20x30 mm for sealing joints is laid along the seam, fixed with a special mesh, dowels, glue or sealant and filled with the next part of concrete.
How to choose the right bentonite cord?
- 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.
