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
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.
UV & Weather Resistance
Stabilized with carbon black and antioxidants to withstand harsh sunlight, extreme temperatures (-50°C to +80°C), and prolonged outdoor exposure.
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.
Puncture & Tear Resistance
High tensile strength (≥25 MPa) and elongation properties protect against punctures from rocks, roots, or equipment during installation and use.
Cost-Effective & Easy Installation
Lightweight and flexible for fast deployment, reducing labor and time costs.
Long service life (20+ years) minimizes replacement needs.

Applications
Fish & Shrimp Ponds: Maintain consistent water levels and prevent seepage.
Aquaculture Reservoirs: Protect against salinity intrusion in coastal areas.
Water Storage Ponds: Ideal for irrigation or decorative water features.
Wastewater Containment: Line treatment lagoons safely.
Installation Guidelines
Subgrade Preparation: Level and compact soil; remove sharp objects.
Liner Deployment: Unroll geomembrane smoothly, allowing slight overlap for welding.
Welding & Seaming: Use hot wedge or extrusion welding for permanent seals.
Anchoring: Secure edges in trenches with anchor bolts or ballast.
Quality Inspection: Conduct spark testing or air pressure checks for seam integrity.
