water swelling stop EVA water swelling water-stop strip material as required color as reuqired specs can be as required
Description:
Water swellingstrip is made from water swelling rubber water line on the basis of the ordinary rubber water-stop. The product swell when contact with the structures and increased the tightness between them which improved water stop and water-proof performance and also solved the problem of circle seepage which puzzled people long term. This series product have been used widely in some key projects and got excellent results.
Features
1. 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 hole 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.
Application
Can be widely applied to various types of concrete structures, such as: dams, reservoirs, subway, culverts, tunnels and other underground works.
