1.45 mil EPDM Pond Liner, 10 ft by 15 ft. This liner is puncture and tearproof, so sharp rocks and root growth won't easily damage it. It also provides a flat surface that helps reduce soil buildup, making pond cleaning quicker and easier. Longlasting and durable. The material is designed for strength to absorb impacts without tearing or puncturing. It offers UV resistance to withstand sun exposure, tear and puncture resistance, and chemical resistance. It can endure extreme weather conditions to provide many years of use. Easy to cut and clean. The liner's good flexibility allows it to bend and fold to fit pond rocks and walls, and it can be cut to fit different pond shapes. The smooth surface promotes a flat, cleaner pond and reduces soil accumulation. For better flexibility, lay the liner out in the sun for 10–15 minutes. Safe for fish and plants. It prevents harmful substances in the soil from penetrating the pond and helps protect water quality, creating a safe environment for wildlife and plants. Use scenarios or retrofit backyard ponds, koi ponds, or water gardens that may include rocks, shelves, or decorative features. Ponds with contours, waterfalls, or irregular shapes where flexible fitting is needed. Outdoor ponds exposed to sun and weather, where durable, longlasting liner performance is important.
