Smooth Black HDPE Geomembrane Sheet for Shrimp Farm Pond Liner

HDPE Geomembrane LinerOur HDPE/LDPE/LLDPE/PVC Geomembrane is a high-performance impermeable lining material fabricated from 100% pure virgin resin, compounded with high-concentration carbon black, anti-ultraviolet agents, anti-oxidants and anti-aging auxiliary additives. Produced with sophisticated multi-layer co-extrusion calendering technology and strict standardized production procedures, this geomembrane boasts remarkable tensile strength, superior tear resistance, excellent puncture resistance against gravel, stones and hard sharp objects, as well as stable weather resistance and long-duration UV aging resistance. It can withstand drastic temperature changes and harsh outdoor exposure all year round without cracking, hardening or degradation.
Acting as a durable, fully impermeable protective barrier with near-zero water and liquid leakage rate, our geomembrane adapts to various complex terrains and construction conditions. It is widely applicable to diversified scenarios including aquaculture breeding, biogas fermentation facilities, solid waste landfills, sewage treatment, agricultural irrigation, reservoir anti-seepage, river slope protection, industrial waste containment and environmental remediation projects, offering long-term stable anti-seepage and pollution isolation solutions for global engineering clients.HDPE Geomembrane Index:

The flexible HDPE material conforms perfectly to pond bottoms and slopes, eliminating soil contamination and reducing disease risk from native soil pathogens. UV-stabilized formulations withstand prolonged sun exposure in tropical climates, while food-grade resin options ensure safety for edible fish and shrimp production. Whether you're operating a small-scale hatchery or a large commercial shrimp farm, our liners cut water replacement costs by up to 70% and simplify pond cleaning and harvesting. Waste Containment For example, landfills, solid waste containment, sewage treatment plants, and industrial waste sites, etc. Engineered for the most demanding containment applications, our HDPE geomembranes deliver exceptional resistance to acids, alkalis, and a broad spectrum of industrial chemicals. They serve as a primary or secondary liner system in landfill cells, preventing leachate migration into surrounding soil and groundwater. The high tensile strength and puncture resistance protect against sharp waste materials and settlement stress. For sewage treatment plants and industrial wastewater lagoons, the smooth surface minimizes sludge buildup and simplifies maintenance — ensuring long-term environmental compliance with minimal lifecycle cost. Biogas Digester & Energy For example, biogas digester liners, covered anaerobic lagoons, livestock waste containment, and agricultural storage, etc. Our flexible geomembrane liners are the ideal solution for biogas digesters and anaerobic lagoon systems. The impermeable HDPE membrane traps methane gas efficiently, maximizing biogas yield for energy production while containing odors and preventing nutrient loss. Reinforced grades handle the structural demands of floating covers and digester walls, even in regions with extreme temperature fluctuations. For livestock and poultry operations, these liners convert manure management from an environmental liability into a revenue stream — producing clean energy and nutrient-rich digestate for fertilizer.Water Management & Canal Seepage Prevention  For example, Irrigation canals, water conveyance channels, reservoirs, dams, river bank protection, slope stabilization, and flood control projects
Water loss through seepage can waste up to 40% of stored or transported water in unlined canals and reservoirs. Our geomembrane liners provide a proven, cost-effective solution — reducing seepage to near zero and protecting water resources from evaporation and contamination. The lightweight, flexible sheets install quickly over large areas, conforming to uneven canal beds and steep reservoir slopes without heavy earthworks. For riverbank and slope protection projects, textured surface options enhance friction stability, preventing erosion and maintaining structural integrity under hydraulic pressurePackaging & Shipping1.
