Geomembrane is a composite made of impermeable geomembrane and geotextile material, which is mainly used for impermeable geomembrane into a cloth membrane and two cloth one membrane, width 4-6m, weighing 200- physical and mechanical properties of 1500g / m2, tensile, tear, bursting and other indicators of high, the product has high strength, good elongation properties, deformation modulus, acid, anti-corrosion, anti-aging, anti-seepage performance Features. To meet the water, municipal, construction, transportation, subways, tunnels, construction of impervious, isolation, reinforcement, crack control reinforcement, civil engineering needs. Due to its selection of polymer materials and the production process adds anti-aging agent, it can be used in unconventional temperature environment. Commonly used in dams, drainage ditch seepage treatment, as well as pollution prevention and waste treatment field.
