Geomembrane liners is also called impervious membrane. With geotechnical cloth as the conduct water layer, high polymer plastic film as the impervious layer, after rolling, hot melting and coating into composite geotechnical anti seepage material. Its thickness is 0.2 mm - 3 mm, in which the thickness of 0.8 mm above is also called geomembrane. The impervious performance of the geotechnical membrane is mainly depend on the impervious performance of the plastic film. Geomembrane liners' rolling, hot melting and coating production process not only maintain its good mechanical properties, but also make the thickness of the composite product film uniform.undation and anti-seepage of subway and culvert.
