The back-adhesive rubber water stop is a waterproof structure installed on the exterior of the concrete deformation joints and settlement joints of underground structures (water-facing side). It leverages the high elasticity of rubber to create elastic deformation under various loads, thereby providing a strong sealing effect that effectively prevents leakage and seepage in building structures, while also offering shock absorption and cushioning functions. This product is widely utilized in foundational engineering, underground facilities, tunnel culverts, water conveyance flumes, dams, and other significant projects, ensuring the durability and waterproof quality of the construction.
High elasticity: Able to adapt to the expansion and contraction deformation of concrete, ensuring the water stop effect.
Good wear resistance and aging resistance: Can maintain stable performance even after long-term use.
Strong tear resistance: Not easily pierced by sharp stones and sharp rebar heads in concrete.
Wide temperature adaptability: Can maintain good performance within a temperature range of -45℃ to +60℃. However, it should be noted that when the temperature exceeds 70℃, or when the rubber water stop is subjected to strong oxidation or erosion by oils and other organic solvents, it should not be used.
