Specifications 1.Light,heat preservation 2. heat insulation, cushioning 3.sound absorption, seal 4.electricity conduct and fire-resist Water swelling strip is not only general prevention, sealing performance, but also by the special protection of water function, has a water expansion effect of special rubber. It can enhance the waterstop and structure compactness, the waterproof, waterproof effect is better.Detailed Product Description1. Waterproof wire adopted water-swelling rubber which will be self-swelling when contact with water and sealed better between the concrete and water and can get excellent waterproof performance.2. Section takes unequal thickness structure which is divided into a strong area, water area and installation area, so that each part can get uniform and reasonable force.3. Telescopic whole outer wall is plane; formwork folder system contact surface is large in construction and difficult to dislocation.4. Setting hole is designed on the installation area which is convenient to fix with the nearest steel bar, difficult to move, construction easily and install firmly.ApplicationCan be widely applied to various types of concrete structures, such as: dams, reservoirs, subway, culverts, tunnels and other underground works.
