1. What Is HDPE Pond Liner?
HDPE Pond Liner, also known as a High-Density Polyethylene Geomembrane, is a type of geomembrane made from high-quality high-density polyethylene (HDPE). It is manufactured using a special formulation of virgin polyethylene resin, carbon black, antioxidants, anti-aging agents, and UV resistance components. These additives enhance the liner’s resistance to UV radiation, making it suitable for exposed conditions. HDPE Pond Liner are known for their durability and ability to withstand higher temperatures, extending their service life. They offer a cost-effective solution for containment applications due to their low cost, excellent chemical resistance, and weathering properties. HDPE Pond Liner is widely used in various industries such as water conservancy, petrochemicals, agriculture, and aquaculture, thanks to its anti-aging and waterproof properties. It meets the requirements set by the GRI-GM13 Specification standard for HD Geomembrane Liners, ensuring its quality and performance. Compared to LLDPE (Linear Low-Density Polyethylene), HDPE Pond Liner are less flexible but provide higher specific strength and can withstand higher temperatures. They are resistant to various solvents and are the most commonly used geomembrane liners worldwide. The exceptional chemical and ultraviolet resistance properties of HDPE make it a cost-effective choice for lining projects. BPM HDPE Pond Liner are manufactured using state-of-the-art automatic production lines and advanced three-layered pressing technology, adhering to the GRI GM13 standard. Compared to traditional materials like concrete, asphalt, and compacted clay, HDPE Pond Liner offer significant advantages in terms of cost-effectiveness, environmental safety, durability, chemical resistance, fast deployment, and easy transportation.
Key Properties of HDPE Pond Liners
HDPE Pond liners are evaluated by properties that impact cost and performance:
• Impermeability: EPDM and HDPE achieve <10⁻¹⁰ cm/s (ASTM D5085), blocking 99.9% seepage—vital for 70% of aquaculture ponds to maintain water quality.
• Tensile Strength: 10–40 kN/m (ASTM D6693), with HDPE averaging 25 kN/m, 25% stronger than PVC for deeper ponds (6–8 ft).
• Puncture Resistance: 1–5 kN (ASTM D4833), where 45 mil EPDM offers 40% more protection than 20 mil PVC against rocks or roots.
• Elongation at Break: 200–1,000% (ASTM D6693), providing flexibility; RPE excels at 400–600%, suiting irregular shapes in 60% of backyard ponds.
• Thickness Range: 0.5–2.0 mm (20–80 mil), with 1.0 mm standard for 50% of 1/4 acre ponds, balancing cost and longevity.
• UV Resistance: 500–1,500 hours (ASTM D4355), with carbon black additives in HDPE extending exposure by 50%.
2. Price of HDPE Pond Liner
For HDPE Pond Liner (10,890 sq ft surface, plus 20–30% for depth/sides totaling 13,068–14,157 sq ft), the average liner cost is $2,500–$12,000 installed, or $0.23–$1.10/sq ft, varying by type, thickness, and labor. This 4–6% rise from 2024 reflects resin hikes (5–7%, ICIS 2025), but bulk saves 15–25%. A basic PVC liner might total $2,500–$4,000, while premium HDPE reaches $8,000–$12,000 for durability. Prices differ regionally: U.S. Midwest $0.50–$1.50/sq ft, West Coast $0.70–$1.80/sq ft (HomeGuide, 2025). Virgin materials add 20–30% but cut failures by 20% (Geosynthetic Institute, 2023).
