HDPE Geomembrane is made by high density polyethylene,also named as seepage-proofing membrane/HDPE sheet) is a kind of waterproofing obstructing material.
Classified by smoothness of the surface, it can be divided into smooth geomembrane with double flat and smooth layers and textured geomembrane with one or two textured surface;
Classified by raw material, it can be divided into HDPE geomembrane, LDPE geomembrane, EVA geomembrane.
