Different people give different names, in fact, they are almost the same, just to see where you use it, what to do. According to the material property, it can be divided into: HDPE (two cloth a film, a cloth one film,), LDPE, PE, GLC, PVC, EPDM, etc.. Different materials are different in practical range, but they all can be called geomembrane or impermeable membrane. Source: Tony hairtail.
Geomembrane is actually the same product as impermeable membrane, but the name is different. Due to seepage prevention effect of impermeable membrane , it is slowly called impermeable membrane by some people.
Composite geo-membrane(composite anti-seepage film) is divided into one cloth and one membrane and two cloths one film, the width of which is 4-6m, and weight is 200 - 1500g/square meters.It is characterized by high index of physical and mechanical properties comprising tensile, tear, bursting resistance, high strength, good extensibility, large modulus?of?deformation, acid and alkali resistance, corrosion resistance, aging resistance, as well as good impermeability. Additionally, it can meet the needs of seepage-proof, isolation, reinforcement, anti crack of irrigation, municipal administration, construction, transportation, subway, tunnels, and other needs of civil engineering. Because its selected high polymer materials and the manufacturing technique have been added antioxidant, it can be used in the non conventional temperature environment. It is commonly used in seepage prevention treatment of dam and drainage ditch, and anti fouling treatment of waste dump.
