HDPE Geo Membrane
Superior Impermeability – Ultra-low permeability (<1×10⁻¹³ cm/s) prevents leakage of liquids, gases, and contaminants.
Chemical Resistance – Withstands acids, alkalis, salts, and solvents; ideal for hazardous environments.
Long Lifespan – UV/oxidation resistant, performs from -60°C to 80°C, with 50+ years of durability.
High Strength – Excellent tensile (20–40 MPa) and puncture resistance for demanding applications.
Cost Efficiency – Fast installation (thermal welding), low maintenance, and superior longevity over clay/concrete.
Product Introduction
HDPE Geomembrane is a high-density polyethylene synthetic liner used as a fluid/gas barrier in engineering and environmental projects.Commonly applied in landfills, mining, water containment, and pollution control.

Types of HDPE Geomembrane
1) Smooth HDPE geomembrane
A smooth HDPE (High-Density Polyethylene) geomembrane is a type of geomembrane with a smooth surface texture.
Smooth HDPE geomembranes are characterized by their flat and smooth surface, which contributes to their impermeability and enhances their performance in preventing the passage of liquids.
2) Single-textured HDPE geomembrane
A single-rough surface geomembrane has one side with a relatively rough texture, distinguishing it from traditional smooth geomembranes. This rough surface may enhance adhesion with other materials and provide additional friction.
One of the primary functions of a single-rough surface geomembrane is to offer an anti-slip surface, improving stability when walking or placing other materials on it. This is crucial for projects that require enhanced stability. By increasing surface roughness, the geomembrane helps prevent soil erosion, protecting the surface cover from weathering and erosion effects.
3) Double-textured HDPE geomembrane
Double-textured HDPE geomembrane is high-density polyethylene (HDPE) geomembrane with rough textures on both sides, providing improved adhesion and slip resistance.
The double-textured design aims to increase the adhesion between the geomembrane and other materials, thereby enhancing stability in engineering projects. It is often used in projects with slopes, which can increased stability, adhesion, and slip resistance of the project, while mitigating soil erosion issues and enhancing overall engineering durability.
