High Density Polyethylene

HDPE features

High Density Polyethylene HDPE exhibits excellent mechanical properties because of its crystalline microstructure, which is why it is the most widely used and trusted polymer globally in the manufacture of geomembranes.

Exhibiting outstanding chemical resistance, UV resistance, tensile strength (it stretches to seven times its own length) and heat resistance, our range of HDPE liners are supplied with a 20-year product warranty.

All of our geomembranes contain a finely calibrated combination of antioxidant additives, stabilizers, and UV-resisting carbon black to meet strict, international quality criteria (American Society for Testing and Materials and the Geosynthetic Research Institute). In fact, HDPE liners are designed to last for over 100 years.We use and recommend HDPE liner as it is globally recognised as a superior product, providing the most cost effective solution for exposed lining projects.

The benefits of HDPE include:

  • high tensile strength
  • ultraviolet, ozone and chemical resistance
  • a seam welding process that allows for 100% testing of all joins, guaranteeing water tightness
  • 20 year product guarantee
  • 2-3% inclusion of carbon black to combat aging, carbon black is universally accepted as being resistant to significant deterioration caused by weathering for 50 years or more
  • an estimated projected life in excess of 100 years for resistance to weathering
