The Vevor pond liner is designed for outdoor ponds and water features with a durable 3-layer construction using PE outer layers and a flexible HDPE middle layer. Its 14 mil thickness helps resist leaks, punctures, and wear for long-term use. The liner can be trimmed to fit different pond shapes and includes four metal buttonholes for easier corner securing during installation. It is suitable for backyard ponds, water gardens, waterfalls, and fountain applications. The material is also intended for use with ponds containing plants and aquatic life.
