Durable HDPE Smooth Geomembrane for Artificial Lake Anti-Seepage Project Breaking Strength 20-80N/mm Elongation At Break 700%

Product Overview
Our HDPE Geomembrane is a premium impermeable liner specifically engineered for artificial lakes, reservoirs, and water containment projects. Crafted from high-quality, UV-stabilized polyethylene, this geomembrane delivers unmatched durability, flexibility, and resistance to environmental stressors, ensuring long-term protection against water seepage and soil contamination.

Key Features

1. Superior Leakage Prevention

   • Ultra-low permeability coefficient (<1×10⁻¹³ cm/s) ensures complete containment of water, preventing seepage and preserving water levels.

   • Seamless welding technology guarantees uniform integrity across large areas.

2. Exceptional Durability

   • Resistant to punctures, tears, and abrasion, even under heavy loads or root penetration.

   • UV-stabilized formulation withstands prolonged sun exposure without degradation.

3. Chemical & Environmental Resistance

   • Impervious to acids, alkalis, salts, and hydrocarbons, making it ideal for diverse water conditions.

   • Non-toxic and eco-friendly, compliant with NSF/ANSI 61 standards for potable water contact.

4. Adaptable & Easy Installation

   • Flexible material conforms to irregular terrain, slopes, and contours.

   • Lightweight rolls enable quick deployment, reducing labor and project timelines.

5. Long Service Life

   • Designed for 50+ years of performance under standard conditions.
