Durable, weatherproof material: Made from density polyethylene (HDPE) with UV resistance. At 0.13 mm thickness, the liner is puncture and tearresistant, contains no plasticisers, and tolerates extreme cold, temperatures and other harsh weather for longterm outdoor use. Effective pond protection: Forms a reliable waterproof barrier that blocks pollutants from soil and runoff, helps maintain clean water, and creates a stable habitat for aquatic plants, fish and other pond animals. Flexible and easy to shape: Prefabricated liners offer strong flexibility and elongation so they conform to irregular pond shapes. You can cut the liner to the exact shape and size you need; installation is simple and can be performed without specialised tools. Wide compatibility and applications: Designed for all sizes of koi/fish ponds, duck ponds, turtle ponds, fountains, waterfalls, reservoirs, planter boxes and water gardens. Also suitable for landscaping projects, water conservancy works and industrial uses such as mining where a durable, waterproof barrier is required. Key specifications and performance Material: density polyethylene (HDPE) Thickness: 0.13 mm Properties: UV resistant, puncture and tear resistant, no plasticisers, withstands extreme temperatures Function: Waterproof, leakproof containment and pollution barrier Installation and use tips Measure the pond area and allow extra overlap at edges before cutting to final shape. Lay the liner on a smooth, compacted base to reduce puncture risk; trim to fit and anchor edges with stones, soil or edging materials. For irregular shapes, make gradual cuts and test fit; the liner's elongation helps it settle into contours without stressing seams. Practical use scenarios Backyard koi pond: Line a newly dug or refurbished koi pond to maintain water clarity, keep soil and runoff separate from the water, and provide a durable, lowmaintenance barrier that supports aquatic life. Small farm duck or turtle pond: Create a leakproof pond that resists damage from animal activity and changing weather, making cleaning and maintenance easier while protecting groundwater. Garden water feature or fountain: Install a liner under a decorative waterfall, fountain or planted water garden to ensure reliable waterproofing and simplify seasonal upkeep. Reliable performance without unnecessary complexity — engineered to protect water features, simplify maintenance, and fit a wide range of outdoor and industrial applications.
