1.0mm 1.5mm 2.0mm HDPE Geomembrane For Landfill
The thickness of the anti-seepage film for landfill is usully between 1.0~2.0mm.The anti-seepage film used in landfills,also known as HDPE Geomembrane(HDPE geotechnical film),is a waterproof barrier material with polyethylene primary resin as the basic raw material.This geomembrane is mainly used to prevent garbage leachate from penetrating into the ground and avoid polluting groundwater.According to different stages of use and requirements,the thickness of HDPE geomembrane varies.
