High-Density Polyethylene HDPE Geomembrane For Reservoir Water Storage & Slope

Product Specification

Product Overview
Our HDPE Geomembrane is a specialized engineering solution designed for reservoir water storage and slope stabilization projects. Engineered to withstand hydraulic pressure, UV exposure, and environmental stressors, this geomembrane ensures reliable water containment, prevents soil erosion, and enhances the structural integrity of reservoir embankments. Ideal for dams, irrigation reservoirs, and flood control systems, it delivers decades of leak-free performance while complying with global hydraulic engineering standards.

Key Features

1. Superior Hydraulic Resistance

   • Ultra-low permeability (<1×10⁻¹³ cm/s) prevents water seepage, maintaining reservoir capacity and protecting adjacent soil structures.

   • Resists hydrostatic pressure and dynamic water flow, even on steep slopes (up to 1:1.5 gradients).

2. Robust Slope Stability

   • High tensile strength (≥28 MPa) and puncture resistance (≥450 N) withstand soil movement, root penetration, and mechanical stress.

   • Textured surface options enhance friction with subsoil, reducing slippage risks on inclined surfaces.

3. Long-Term Durability

   • UV-stabilized with 2-3% carbon black additives to resist degradation from prolonged sun exposure.

   • Operates reliably in extreme temperatures (-60°C to +80°C), suitable for freeze-thaw cycles and arid climates.

4. Environmental Safety

   • Non-toxic, NSF/ANSI 61-certified for potable water contact.

   • Prevents soil erosion and protects aquatic ecosystems from contamination.

5. Efficient Installation

   • Prefabricated panels or wide rolls (up to 8m) minimize seams, accelerating deployment on large-scale projects.

   • Compatible with geotextiles, geogrids, or concrete layers for hybrid reinforcement systems.

Installation Best Practices

1. Subgrade Preparation: Compact and level the slope surface; remove sharp debris.

2. Seam Welding: Use dual-track hot wedge welding for slopes ≥20°; conduct non-destructive spark testing.

3. Anchoring: Secure geomembrane edges in anchor trenches with concrete or compacted soil.

4. Protection Layer: Cover with geotextile or soil to shield against UV and mechanical damage.
