Hydrophilic Water Stop is made from water-swelling rubber water line to the basis of the ordinary rubber water-stop. The product will swell when contacted with the structures. As a result, the tightness is fastened between the water stop and water-proof performance is improved and the problem of circle seepage which puzzles people in a long time is solved. This series of products have been used widely in some key projects and have gotten excellent results. |
