HDPE verses LLDPE Geomembranes – Which Is Better?

Over the past 40 years, HDPE (High Density Polyethylene) and LLDPE (Linear Low Density Polyethylene) geomembranes have become the dominant materials used for environmental containment. Widely used across various industries including municipal waste, water, mining, oil & gas, renewable energy, agriculture, and environmental remediation, both materials offer:

  • Excellent chemical resistance
  • Strong UV stability
  • Long-term durability
  • Economical cost

So, which is better?
The answer depends on the specific application and site conditions. The article provides guidance for selecting the appropriate material.
