Anti-seepage HDPE Smooth Geomembrane For Agriculture Project Fish Pond Liners Width 1m-9m Length 30-100m Thickness>0.5mm

Our smooth geomembrane is a high-performance, impermeable liner specifically engineered for fish pond and aquaculture applications. Made from premium-grade high-density polyethylene (HDPE), this geomembrane ensures superior water retention, chemical resistance, and long-term durability. Ideal for preventing seepage in freshwater or saltwater fish ponds, it safeguards water levels, reduces maintenance costs, and creates a stable environment for aquatic life.

Key Features & Benefits

1. Exceptional Impermeability

   • Zero Leakage: With an ultra-low permeability coefficient (<1×10⁻¹³ cm/s), our geomembrane effectively prevents water loss and groundwater contamination.

   • Seam Strength: Thermally welded seams ensure uniform integrity, critical for large-scale fish pond projects.

2. UV & Weather Resistance

   • Stabilized with carbon black and antioxidants to withstand harsh sunlight, extreme temperatures (-50°C to +80°C), and prolonged outdoor exposure.

3. Chemical & Biological Resistance

   • Resists degradation from fertilizers, algae, salts, and organic acids commonly found in aquaculture environments.

   • Non-toxic and eco-friendly, safe for fish and aquatic ecosystems.

4. Puncture & Tear Resistance

   • High tensile strength (≥25 MPa) and elongation properties protect against punctures from rocks, roots, or equipment during installation and use.

5. Cost-Effective & Easy Installation

   • Lightweight and flexible for fast deployment, reducing labor and time costs.

   • Long service life (20+ years) minimizes replacement needs.
