Pond Liner HDPE 300/500 Micron 50 Years Long Life Puncture Resistant 2x2m to 8x16m Garden pool landscaping reservoir/lotus pond/pond 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.
