Waterproof and moisture permeable membrane composite fabric is also called composite geomembrane, composite geomembrane, two fabrics and one membrane. There are two main production processes, one is the laminating process, and the other is the thermal compounding process. At present, the composite geomembrane purchased by domestic large-scale projects is mainly thermal composite technology.

The coating process is that plastic particles are heated and coated on geotextile by special equipment, and then covered with a layer of geotextile, and pressed and molded. Thermal compounding technicians heat the produced plastic film in the oven to make it adhere to the upper and lower layers of geotextile. The thickness of the composite geomembrane produced by thermal composite technology is relatively uniform, and all indexes are easy to reach the standard with little change.
