" />Geomembrane liners are available in several material types, each with distinct properties. Understanding the differences helps you select the right liner for your application.
HDPE (High-Density Polyethylene)
HDPE is the most widely used geomembrane material.
- Advantages: Excellent chemical resistance, UV stability, high tensile strength, cost-effective
- Best for: Landfills, mining, reservoirs, canals
- Thickness range: 0.5mm-3.0mm
- Temperature range: -40°C to 60°C
LLDPE (Linear Low-Density Polyethylene)
LLDPE offers greater flexibility and elongation than HDPE.
- Advantages: Superior flexibility at low temperatures, higher elongation, easier welding
- Best for: Contour lining, pond liners, irregular shapes
- Thickness range: 0.5mm-2.0mm
PVC (Polyvinyl Chloride)
PVC geomembrane is flexible and widely used in specific applications.
- Advantages: Highly flexible, easy to install, good for vertical walls
- Limitations: Lower chemical resistance, plasticizer migration over time
- Best for: Roof gardens, water features, temporary covers
Which Should You Choose?
For most permanent waterproofing projects, HDPE is the preferred choice due to its proven long-term performance. For cold climates or complex shapes, LLDPE offers better flexibility. PVC is suitable for temporary or specialty applications where its flexibility is needed.
