As a new type of material, HDPE/PVC impervious membrane has outstanding performance, stability, and can be processed as required. It has been widely used in dam, reservoir, but also channels, sewage ponds, swimming pools, buildings, underground structures, garbage collection, environmental engineering fields. In 1930s developed countries started to use this technology widely and our country gradually promote the use of HDPE impervious membrane in some projects from the 1980s. 1.Environmental protection, sanitation (such as landfill, waste water treatment, toxic and harmful chemicals disposal sites, storage of dangerous goods, industrial waste, construction and demolition waste, etc.) 2.
