Application scenarios of HDPE geomembrane

As a core geosynthetic material, geomembrane’s core functions are seepage prevention, isolation, reinforcement, and corrosion protection. According to the material, it can be divided into HDPE (high-density polyethylene), LDPE (low-density polyethylene), PVC, EVA, textured geomembrane, etc., with different materials suitable for different scenarios.

Water conservancy projects (core area)

1. Seepage prevention for reservoirs, water storage ponds, and drinking water pools (to prevent water leakage);
2. Lining of river channels and canals (to reduce water erosion and improve water conveyance efficiency);
3. Seepage prevention and reinforcement of dikes and cofferdams (to prevent piping and enhance stability);
4. Seepage prevention for artificial lakes, landscape ponds, and fountain pools.

Environmental protection projects (essential needs)

1. Landfills (municipal/industrial waste): Bottom seepage prevention, slope seepage prevention, leachate collection layer isolation (to prevent soil and groundwater contamination);
2. Wastewater treatment plants: Oxidation ponds, sedimentation ponds, sludge landfill seepage prevention;
3. Mine revegetation: Tailings dam seepage prevention (to prevent heavy metal pollution), mine leachate collection;
4. Chemical industrial parks: Chemical storage tank foundation seepage prevention, waste liquid pool seepage prevention.

Agriculture and animal husbandry

1. Greenhouses and drip irrigation systems: Retain soil moisture and prevent water and fertilizer leakage;
2. Aquaculture ponds (fish, shrimp, crab, turtle): Prevent seepage, escape, and easy cleaning;
3. Saline-alkali land improvement: Isolate the saline-alkali layer and prevent soil salinization.

Traffic Engineering

1. Highway/Railway Subgrade: Isolates different soil layers (prevents subgrade settlement and frost heave), enhances bearing capacity;
2. Tunnels and Subways: Waterproof lining (used in conjunction with geotextile to prevent water seepage);
3. Airport Runways: Foundation isolation, seepage prevention, and moisture protection.

Architecture and Municipal Engineering

1. Rooftop greening and underground parking garage roofs: waterproofing and root-penetration prevention (requires root-penetration-proof geomembrane);
2. Basements and reservoirs: waterproofing and seepage prevention;
3. Garbage transfer stations: ground seepage prevention and sewage collection.

Emergency Engineering

1. Flood control: Rapidly construct seepage-proof dikes and seal leaks;
2. Temporary reservoirs and drainage ditches: Emergency water supply/drainage.

Other special scenarios

1. Petrochemical industry: Oil tank foundation seepage prevention and oil spill isolation;
2. Golf courses: Artificial lake and sand pit seepage prevention;
3. Marine aquaculture cages: Bottom seepage prevention and pollution prevention.
