Heavyduty HDPE pond liner, 0.12 mm thickness, UV resistant, puncture and tearresistant Key benefits Durable protection: Made from strength HDPE fabric at 0.12 mm thickness to resist UV damage, punctures, and tears in harsh outdoor environments. Keeps water clean: Acts as an impermeable membrane to block soilborne pollutants and minimize sediment buildup, making pond maintenance and cleaning easier. Flexible fit: flexibility conforms to irregular shapes and contours, so it works for custom or uneven pond bases. Easy handling and installation: Lightweight material that is simple to lay, position, and trim on site. What it does for you Prevents leaks and contamination by creating a continuous waterproof barrier between water and soil. Reduces longterm maintenance by limiting soil intrusion and organic buildup. Withstands exposure to sun and rough landscaping conditions without rapid degradation. Material and performance Material: density polyethylene (HDPE) fabric Thickness: 0.12 mm Properties: UV resistant, puncture resistant, tear resistant, flexible, lightweight Function: Impermeable membrane film that provides a stable horizontal surface and prevents pollutants from entering the water Compatibility and applications Suitable for koi ponds, fish ponds, and backyard water gardens Can be used under waterfalls, streams, fountains, and pondless water features Effective in rugged or uneven landscapes where a flexible, durable liner is required Typical use scenarios 1) Koi or fish pond installation: Lay the HDPE liner to form a reliable, impermeable base that protects fish habitat from soil contaminants and prevents leaks. 2) Backyard waterfall or stream: Use the flexible liner to shape cascades and channels over irregular rockwork while maintaining a watertight barrier. 3) Fountain or pondless feature: Line the reservoir or buried basin to contain water without needing a constructed concrete basin, simplifying installs and repairs. Installation and care tips Trim and fold the liner to fit contours, allowing slight overlap at seams or edges where . Use underlayment where rock or sharp edges are present to reduce puncture risk. Periodically inspect for surface damage; small punctures promptly with a compatible patch. This HDPE pond liner provides a practical, longlasting solution for water features that require a flexible, impermeable barrier resistant to UV, punctures, and tears.
