1.Performance and Features
Rubber water stop is the use of rubber elasticity and compressibility, will produce under various loads and made of compression sealing member, it has been widely used in water conservancy and hydropower projects, dams culvert, subway tunnels, high-rise building in the basement Deformation and parking in other projects. Rubber water is pouring concrete is embedded in the deformation crack and concrete fused play a waterproof seal, effectively prevent the deformation crack at building leakage, ensure that the project's life。
