Bentonite cord is a profiled waterproofing material in the form of a round or rectangular profile bundle of various sizes. Due to its composition, it has high adhesion to concrete, metal and plastic.

Bentonite cord Bentizol® is made according to a unique formula and complies with international stadards.

When hydrated, it increases in volume up to 200%, providing sealing of concreting joints, holes and other places where water tends to penetrate.
