Key benefits Protects water quality: forms a continuous barrier between soil and water to prevent soilborne pollutants from entering the pond and contaminating plants and animals. Prevents leaks and seepage: reduces water loss by sealing the pond base and sides, lowering the risk of costly repairs and frequent refilling. Keeps the pond clean and level: reduces soil accumulation and helps maintain a smooth, even water surface for better circulation and appearance. Durable and lowmaintenance: made from quality HDPE that is flexible and UVresistant for longterm outdoor use. What it does and why you need it Acts as a reliable barrier between soil and pond water to stop contamination and stabilize the pond structure. Prevents uneven settling and soil intrusion that cause turbidity, poor water quality, and stress to fish and plants. With its UV resistance and flexibility, the liner resists sun damage and conforms to contours without cracking, extending the service life of the pond. Key attributes Material: density polyethylene (HDPE) — flexible and resistant to UV exposure. Color: Black — suitable for outdoor installations and most water features. Function: Waterproof lining that prevents leaks, soil contamination, and soil buildup. Compatibility: Designed for outdoor ponds, koi fish ponds, waterfalls and other water features; also widely used in construction, agriculture, paving and surface protection. Practical use scenarios Backyard koi pond: Line the pond to protect water quality and prevent leaks, preserving a healthy environment for fish and aquatic plants. Waterfall or decorative feature: Use the flexible HDPE liner to shape cascades and pools while preventing seepage and soil contamination around the structure. Agricultural or construction applications: Line reservoirs, retention basins or surface areas where a durable, UVresistant barrier is required to control water and protect surfaces. Why choose this liner quality HDPE offers a balance of flexibility and toughness for outdoor pond installations. UV resistance helps maintain integrity in direct sunlight without rapid degradation. Versatile use across water features, landscaping and practical construction or agricultural applications. Suitable for: outdoor ponds, koi fish ponds, waterfalls, decorative water features, construction, agriculture, paving and surface protection.
