ASTM D HDPE Geomembrane Pond Liner 1mm



1.Introduction


ASTM D HDPE Geomembrane Pond Liner 1mm is widely used in seepage-proofing projects. Before laying HDPE geomembrane, it should be with qualified acceptance documents accordingly by civil engineering. When laying geomembrane, we should strive to weld the least; on the premise of guarantee quality, we should try our best to save raw materials; at the same time, it is easy to ensure the quality. The lap joint between film and film, its width is generally not less than 10 cm. And in a corner and deformity location, the  joint length should be shorten as far as possible. When laying geomembrane, we should avoid any artificial fold; when the temperature is lower, we should try to tighten, paving the geomembrane. After finishing the geomembrane laying, we shouldn’t walk on the surface of the membrane, or move tools on surface, etc.,
