Heavy Duty Pond Liner — Durable HDPE, 0.12mm thickness Key benefits Long-lasting protection: Made from durable HDPE, the 0.12mm thickness resists extreme weather and is designed for long-term outdoor pond use. Protects water quality: Acts as a barrier to keep harmful substances in the soil from entering the pond, helping maintain cleaner water for fish and plants. Flexible and customizable: Easily bends and folds to fit irregular shapes and can be cut to the exact layout you need. Simple, tool-free installation: Bottom layer provides a flat surface that reduces soil build-up; the liner can be installed without special tools and includes a round cobblestone-textured top layer for added surface protection and appearance. Safe for wildlife and plants: Manufactured for environmental safety and suitable for ponds containing fish and aquatic plants. Features Material: High-density polyethylene (HDPE) for durability and UV resistance. Thickness: 0.12mm to balance flexibility with puncture and weather resistance. Surface: Bottom layer creates a stable base; top has a round cobblestone texture for added protection. Function: Waterproof pond film that prevents leaching from surrounding soil and supports easier pond maintenance and cleaning. Practical applications Backyard garden pond: Shape and size the liner to fit irregular natural ponds, planted ponds, or decorative water gardens. Fish and plant ponds: Suitable for ornamental fish ponds and aquatic plant beds where water quality protection is important. Small water features and fountains: Use the liner to create stable, watertight bases for patio water features or tiered fountains. Installation and maintenance Layout the liner on a cleared, relatively smooth base to reduce puncture risk. Fold and trim to match the pond shape; overlap edges where necessary and secure with appropriate edging or weights. The flat bottom layer minimizes soil accumulation, simplifying routine cleaning and debris removal. Inspect periodically for damage; small repairs can be made with compatible patch materials. Performance and compatibility Designed for outdoor pond installations and compatible with planted or fish-containing ponds. Resists weathering and supports long-term performance when installed on a prepared base. Environmentally designed to be safe for aquatic life when used as intended. This Heavy Duty Pond Liner provides a durable, flexible, and easy-to-install solution for creating or refurbishing ponds and water features while protecting water quality and supporting aquatic life.
