Water stop-a strip made and installed to prevent water infiltration (flow and diffusion). Generally used for waterproof construction joints, mainly used in infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy, subways and other projects. The function is to use the high elasticity and compressive deformation ability of rubber to produce elastic deformation under various loads, which plays the role of fastening and sealing, effectively prevents water leakage and leakage of building components, and plays the role of shock absorption and buffering. So as to ensure the service life of engineering buildings.
Water stop is divided into rubber water stop and plastic water stop according to materials; According to the use position, it can be divided into embedded type and back-attached type; According to the strength, it is divided into ordinary water stop and steel edge water stop.
