The material is widely applied to irrigation area channel seepage-proofing engineering, and is combined with construction practices and application technologies of shallow speaking composite geomembranes.
The two cloth films and the one film are made of plastic films as anti-seepage base materials and are compounded with non-woven fabrics to form the geotechnical anti-seepage material. Its barrier properties are mainly determined by the barrier properties of the plastic film. The plastic film for seepage-proofing application mainly contains polyvinyl chloride (PVC) and Polyethylene (PE), and they are a high-molecular chemical flexible material, and have small specific gravity, strong extensibility, high deformation-adapting capacity, corrosion resistance, low-temperature resistance and good frost resistance.
