JWELL 8m geomembrane equipment is in operation in foreign customer factories. Products of PE waterproof roll/geomembrane extrusion line are mainly used for concrete pouring is set in the construction joint and deformation joint and concrete as one of the basic engineering, such as tunnels, culverts, aqueducts, DAMS, liquid storage structures, underground facilities. It takes advantage of the elastic deformation characteristics of polymer materials to play a leakproof role in building structural joints and has the characteristics of corrosion resistance and good durability.
