GeoMembrane Introduction:
HDPEGeo Membrane is the most widely used geosynthetic liner today. PondLiner enjoys particularly high acceptance in the pondconstruction.
Geo MembraneUsage:
HDPE Geo Membrane is mostly used for solid waste containment (e.g.sanitary land fill), mining, and water containment applications(e.g. lagoon and water reservoir).
