Home > Product >HDPE Geomembrane

HDPE Geomembrane (High Density Polyethylene Geomembrane) is a high-performance impermeable geosynthetic liner. It is produced from virgin HDPE resin blended with carbon black, antioxidants, UV stabilizers and other additives via extrusion or calendering processes.

There are two main types: smooth HDPE geomembrane and textured HDPE geomembrane (single-sided / double-sided textured). The textured version provides higher friction coefficient for slope stability, while the smooth type features easier welding and installation.

Summary of Core Characteristics and Advantages

HDPE geomembrane is a high-density polyethylene liner featuring outstanding impermeability, strong chemical and UV resistance, and superior mechanical performance with high tensile, tear and puncture resistance. Flexible and weldable on site, it adapts to complex terrain, resists microbial decay and root penetration, and is available in smooth or textured surfaces. As a cost-effective, non-toxic anti-seepage barrier, it is widely adopted in landfills, mining ponds, wastewater projects, aquaculture and reservoir anti-seepage works.

HDPE Geomembrane

HDPE geomembrane is manufactured mainly in accordance with GRI-GM13 (international mainstream standard), ASTM test standards and China GB/T 17643. It adopts virgin HDPE resin with density ≥0.940 g/cm³. Available thickness ranges from 0.5 mm to 3.0 mm; common roll width is 2–12 m, roll length customizable from 50 m to 200 m. Two surface types are optional: smooth HDPE geomembrane and single/double-sided textured HDPE geomembrane. Black is standard color, blue, green and other colors can be customized. Full factory inspection and third-party SGS test reports are available to verify mechanical, anti-aging and chemical resistant performance.

Application Scenarios

HDPE geomembrane

HDPE geomembrane is widely used in various anti-seepage projects due to excellent impermeability, chemical resistance and mechanical strength, while customized selection is required for different working conditions. For municipal landfills, 1.5–2.0 mm single or double-sided textured HDPE geomembrane is commonly adopted. Hazardous waste landfills demand stricter standards, requiring virgin material geomembrane above 2.0 mm. 1.0–1.5 mm smooth liner is used for artificial landscape lakes. 0.5–1.0 mm eco-friendly geomembrane is suitable for aquaculture ponds. 1.5–2.0 mm geomembrane is applied in tailings ponds with chemical resistance assessment. It can be used in biogas digesters to resist high-concentration organic acids. 1.0–1.5 mm liner is adopted for green roof and underground garage roof anti-seepage. 0.5–1.0 mm puncture-resistant geomembrane with good cost performance is the choice for agricultural reservoirs and irrigation canals.

Scenario	Recommended thickness	Surface type	Key indicators
Landfill	1.5-2.0mm	Rough surface	NCTL、Chemical resistance
Artificial lake	1.0-1.5mm	Smooth surface	Weldability, flexibility
Aquaculture	0.5-1.0mm	Smooth surface	Environmentally friendly, microbial resistance
Tailings storage facility	1.5-2.0mm	Rough surface / Smooth surface	Chemical resistance, strength
Agricultural water storage	0.5-1.0mm	Smooth surface	Puncture resistance and cost-effectiveness
