The PVC waterproofing membrane for tunnel is a kind of high-quality, high-molecular waterproofing sheet, which is added with plasticizer, anti-ultraviolet, anti-aging, stabilizer and other processing aids through PVC resin.
PVC roofing membranes is a thermoplastic PVC coil. The coil is made of polyester fiber fabric or glass fiber as a reinforcing rib. Through a special extrusion coating process, the double-sided polyethylene oxide plastic layer and the middle polyester or glass fiber reinforced ribs are combined to form a polymer coil.
The PVC waterproofing membrane for tunnel is a kind of high-quality, high-molecular waterproofing sheet, which is added with plasticizer, anti-ultraviolet, anti-aging, stabilizer and other processing aids through PVC resin. It is made from extrusion process. Due to the unique product formula, this product has a life span far beyond that of ordinary waterproofing materials. The entire waterproofing system has a long-life span. The roof is more than 20 years and the underground are more than 50 years. It has been widely used in construction, Tunnel Projects and civil engineering.
