HDPE Geomembrane
Smooth high-density polyethylene liner for landfills, ponds, canals and tanks, supplied from 0.5 mm to 2.0 mm thick.
Overview
Smooth HDPE geomembrane is extruded from high-density polyethylene resin with carbon black and antioxidant additives. It has very low permeability to liquids and gases, strong chemical resistance and good UV stability, which makes it a standard liner for landfills, mining ponds and water storage. Sheets are joined on site by hot-wedge or extrusion welding and the seams are tested before the liner is covered.
Features
- Very low permeability to liquids and gases
- Resistant to most acids, alkalis and landfill leachate
- Carbon black and antioxidant package for outdoor exposure
- High yield strength and puncture resistance
- Seamed on site by hot-wedge or extrusion welding
