Advantages of rubber waterproof water stop bentonite  

   1. It is permanently active system, which swells up to approximately (150%~300%).

   2. It is an ecological and user friendly system: simple and quick to install by means of gun nailing. 

   3. The composition of bentonite water-stop prevents premature swelling.

   4. The waterstop has a proven track record in water treatment plants, water purification plants, water tanks, 

       metro works and other concrete structures subject to high water pressure
