Product Name: Geomembrane
Characteristics of Geomembrane:
Geomembrane is an anti-seepage product with high polymer as basic material. It mainly funtions as prevent liquid from leakage and gas volatization. Raw meterial type are :VLDPE, LDPE, LLDPE, PB, HDPE, MDPE, EVA etc.
Applications of Geomembrane:
In geotechnical engineering,Geomembrane mainly funtions as antiseepage and separation, meanwhile, reinforcement and protection emerge together with anti-seepage in projects as earth rock fill dam, rock fill dam, masonry dam, concrete dam, tailing dam, sewage reservoir and reservoir area, channel, reservoir etc; water tight lining function in subway, basement and tunnel; road and railway groundwork anti-seepage etc.
