HDPE Liner Application
Excellent impermeability with ultra-low permeability, effectively preventing leakage.
Strong resistance to chemicals, acids, alkalis and corrosion for long service life.
Good flexibility and tensile strength, adapting to ground deformation.
UV and weather resistant, stable in extreme temperatures.
Lightweight, easy to weld and install, lowering overall project cost.
Chapter 1 General Introduction to HDPE Liner
HDPE (High-Density Polyethylene) liner is a high-performance impermeable geosynthetic material, widely used for anti-seepage and containment projects. It features excellent chemical resistance, durability and waterproof performance, effectively preventing liquid/gas leakage, adapting to harsh environments, and serving as a core material for environmental protection, water conservancy and mining engineering with stable long-term service.

Chapter 4 Application Fields of HDPE Liner
1. Landfill & Waste Management: Seals landfill sites to block leachate leakage and control soil pollution.
2. Mining Industry: Prevents acid mine drainage and tailings seepage to protect water sources.
3. Water Conservancy: Used for reservoirs, ponds and canals to enhance waterproofing.
4. Aquaculture: Lined in fish ponds and shrimp ponds to maintain water quality.
5. Petrochemical Engineering: Isolates oil tanks and chemical pools to avoid contamination.
6. Environmental Remediation: Treats contaminated sites and blocks harmful substance diffusion.
Chapter 5 HDPE Liner Installation Steps
First, clean and level the base surface, removing sharp objects and debris to avoid membrane damage.
Second, unroll and lay HDPE liners smoothly, reserving proper overlap for welding.
Third, perform hot wedge welding on seams, strictly controlling temperature and speed for firm bonding.
Fourth, conduct air pressure and leak tests on welded joints to check tightness.
Fifth, repair damaged areas timely and fix edges firmly. Finally, conduct full inspection and acceptance before backfilling or usage.
