Features: Low permeability HDPE lining systems are secure because leachate does not penetrate them Methane gas will not escape from the HDPE cover system Rainwater will not infiltrate an HDPE cap Chemical resistance HDPE, resistant to a wide range of chemicals, is not threatened by typical solid or hazardous waste leachates Suitable for sludge and secondary containment around chemical storage facilities Ultraviolet resistance HDPE's resistance to UV exposure is further enhanced by the addition of carbon black Additionally, with the absence of plasticizers, volatilization is not a problem Reflective factor Geotec offers its HDPE geomembranes in white and black A white surface helps mitigate liner temperature extremes and aids visual inspection

geomembrane Introduction
Our geomembrane is manufactured from High Density Polyethylene resins. The surfaces of both sides are smooth. The products are manufactured by the technology of coextrusion-blown triple layer. It provides geomembranes with specific properties on each layer, e.g. bicolor and/or textured designs.
Performance
Excellent physical and mechanical performance, high tearing resistance, good deformation adaptability, high puncture resistance, high aging resistance, high UV resistance, anti-acid & alkali, excellent low & high temperature resistance, innocuous, long life span, perfect water proof performance, seepage and humidity resistance.
Application
The projects of Landfill site, bank, dam, storage reservoir, channel, irrigation, highway, railway, tunnel, drinking tank, salt field bittern pan, chemical liquid storage, treatment tank, artificial lake and riverway etc.
