LLDPE Geomembrane Liners Designed For Waste Containment
Introduction:
The LLDPE Geomembrane is a linear low-density polyethylene liner known for its superior flexibility and strength. It is ideal for applications where a high degree of adaptability is required, such as in agricultural ponds, landfills, and irrigation canals. This material combines excellent tear and puncture resistance with strong chemical resistance, ensuring a reliable barrier in demanding environments. Its lightweight nature makes it easy to handle, reducing installation time and labor costs.
Key Features:
Flexible and Adaptable – LLDPE offers excellent flexibility, making it suitable for uneven surfaces.
Superior Tear Resistance – Provides enhanced protection against punctures and tears.
Excellent Chemical Resistance – Withstands exposure to a wide range of chemicals and environmental elements.
Easy Installation – Lightweight and flexible, making it easy to transport and install.
Application:
Deformation-Sensitive Projects :Landfill closures, mine leaching ponds, and tailings ponds use Geomembrana 2mm or 60 mil HDPE liners (to mitigate settlement deformation).
Complex Structure Anti-Seepage:
Culverts, curved tunnel surfaces, and sewage pipe linings use 30 mil HDPE liners or Geomembrana 40 mil HDPE (due to its high conformability).
Ecologically Sensitive Projects:
Aquaculture ponds (fish/shrimp ponds) use 0.5mm anti-seepage liners or 40 mil HDPE geomembranes (to ensure non-toxicity) and drinking water reservoirs.
Small and Medium-Sized Water Conservancy Seepage Control:
Anti-seepage coatings on the bottom and slopes of small and medium-sized reservoirs, mountain ponds, and irrigation ditches.
Agricultural Facilities Seepage Control:
Moisture-proof layers on greenhouse foundations, integrated water and fertilizer storage tanks, and anti-seepage liners for artificial wetlands.
Municipal Small-Scale Liquid Storage Facilities:
Secondary anti-seepage coatings for rainwater collection tanks and regulating tanks at small sewage treatment plants.
