Cord bentonite round d22 mm for waterproofing and sealing holes, 5 r.m. Sanpol
Waterproofing bentonite cord "Hydrostop" SANPOL round 22mm is a material designed to ensure water resistance and sealing holes for the coupling screw.During installation, a plastic non-removable PPE tube d22 is inserted into the formwork before pouring concrete, in which there is a coupling screw for tightening the formwork panels. After decoupling, when removing the coupling screw from the tube, it is necessary to close the hole. A round bentonite cord is ideal for sealing holes that remain in concrete, after which the edge is covered with a waterproofing solution. The mounting system is very simple. 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. Excellent technological performance and an easy installation method make it possible to use the product as an insulating material for sealing holes in underground construction, hydraulic structures and civil engineering. Bentonite cord "Hydrostop" has a diameter of 22mm and is used in monolithic construction to seal the holes for the coupling screw. Made of bentonite clay, it swells upon contact with water and increases in volume by 4 times. 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.

How is bentonite cord of round cut applied?
The bentonite cord of the round cut d22 is inserted into the hole after the coupling screw and covered with a repair mixture
What is the working principle of bentonite cord?
Bentonite cord securely and firmly adheres to the concrete surface, filling seams, junctions 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.
