Feature
Expansible strip can expand when it is in touch with water.
Adapt the deformation of concrete.
High elasticity and tensile strength.
Can arise compression deformation under various loads.
Resistant to wear, aging, rust.
Good waterproof performance.
Easy to install.
Application
Reinforced rubber waterstop is mainly used in construction joints, expansion and contraction joints of concrete structures, such as dams, reservoirs, subway, culverts, tunnels, cisterns, swimming
pools, roof, aqueducts, basement, artificial lakes, sewage treatment plants, etc.
