LLDPE Geomembrane
Flexible linear low-density polyethylene liner that follows uneven subgrades and tolerates differential settlement.
Overview
LLDPE geomembrane trades some of the stiffness of HDPE for much higher flexibility and elongation. It follows uneven subgrades, tolerates differential settlement and is easier to fold and deploy in cool weather. It suits pond and canal liners, heap leach pads, tank linings and landfill caps.
Features
- Flexible sheet that conforms to uneven ground
- High elongation at break for movement and settlement
- Good tear and puncture resistance for its thickness
- Carbon black stabilised for outdoor exposure
- Seamed on site by hot-wedge or extrusion welding
