The Vevor pond liner is designed for outdoor ponds, water gardens, waterfalls, and fountains with a durable 3-layer reinforced PE construction. Its 14 mil thickness helps resist leaks, punctures, tears, and surface wear for long-term use. The liner can be trimmed to fit different pond shapes and includes reinforced hemmed edges for added durability. Four metal buttonholes at the corners help simplify securing the liner during installation. It is suitable for ponds with plants, koi, fish, ducks, and turtles.
