HDPE Fish Pond Liner Waterproof & Leak Proof 300 Micron 500 Micron Multiple Sizes Available 2x2M to 8x16M fish pond liner black Geomembrane HDPE material Garden pool landscaping waterproof membrane dedicated for aquaculture ponds Durable for 50 years

📌300-Micron Standard GeomembraneProduct Introduction : The 300-micron (0.3mm) standard impermeable membrane is made primarily of high-density polyethylene (HDPE), featuring excellent impermeability and chemical stability. It has a tensile strength at break of 28 MPa and an elongation rate of up to 700%, allowing it to accommodate slight base surface deformations.✨ Core Advantages1️⃣. Cost-Effective: Moderate thickness, with costs approximately 50% lower than traditional impermeable materials, suitable for small to medium-sized projects with limited budgets.2️⃣. Corrosion Resistance: Can withstand corrosion from more than 80 chemical media, including acids, alkalis, and salts, widely used in fish ponds, lotus ponds, and general wastewater treatment.3️⃣. Easy Construction: Supports hot-melt welding with high seam strength; 4-12 meter wide design reduces joint waste.4️⃣. Applicable Scenarios: Suitable for low-load environments such as aquaculture, agricultural irrigation, and landscape ponds.----------------------------------------------------------------------------------------📌500-Micron Thickened Anti-Seepage MembraneProduct Introduction : The 500-micron (0.5mm) thickened anti-seepage membrane is made using an enhanced polyethylene formula and calendering process, resulting in a 30% increase in mechanical strength and significantly better puncture resistance compared to the standard version.✨ Core Advantages1️⃣. High Durability: Excellent UV and aging resistance, with a lifespan of over 50 years in outdoor environments.2️⃣. Heavy-Duty Protection: Suitable for harsh environments such as landfills and hazardous waste disposal sites, effectively resisting heavy machinery compaction.3️⃣. All-Weather Adaptability: Temperature resistance ranging from -70°C to 110°C, ensuring stable seepage protection in both extremely cold and hot regions.4️⃣. Applicable Scenarios: Ideal for projects requiring high-strength seepage prevention, including chemical industrial parks, mining tailings ponds, and dam reinforcement.
