HDPE, PP Waterproof Sheet Production Line

Waterstop boards are made by extrusion molding of high-density polyethylene (HDPE) and polypropylene (PP) resins. They are primarily used in foundation projects where they are set in construction joints and deformation joints during concrete pouring, forming an integral part with the concrete structure, such as tunnels, culverts, water conduits, dams, liquid storage structures, and underground facilities. They utilize the elastic deformation characteristics of high polymer materials to prevent leakage and seepage at the joints of architectural structures, and they also feature good corrosion resistance and durability.
