Uncontrolled ground seepage causes constant water loss and allows soil-borne bacteria to enter fish breeding zones. Our 0.75mm black HDPE geomembrane provides a smooth, watertight bottom barrier that isolates farm stock from raw earth. This dense fish farm waterproofing sheet keeps water levels steady, stops bottom soil erosion caused by water aerators, and prevents muddy sediment from mixing with fish feed.

Technical Specifications

Why Choose Our Geomembranes?

• Non-Toxic Pure Resin: Manufactured from virgin polyethylene with zero recycled additives, ensuring safe containment for edible fish.

• Smooth Surface for Quick Cleaning: The slick finish prevents algae and fish waste from sticking, allowing fast wash-downs between harvest cycles.

• Stands Up to Motorized Aerators: Resistant to surface wear and thinning caused by continuous water currents from paddlewheel equipment.

• Precision Factory Edge Trimming: Features clean outer margins to ensure simple, leak-proof heat welding during field installation.

Primary Applications

• Commercial Tilapia & Catfish Ponds: Lining earthen grow-out basins to maintain stable water volumes and prevent soil disease transmission.

• Fish Hatchery Spawning Channels: Creating clean, mud-free raceways for sensitive fry and juvenile fish culture.

• Aquaponics Water Reservoirs: Sealing closed-loop water holding tanks to stop nutrient-rich water from leaking into subsoil.

• Settlement & Filtration Ponds: Lining farm wastewater basins to settle solid organic waste before water recirculates.
