A pond liner is a waterproof material used to create and maintain artificial ponds or water features. Typically made from materials like PVC, EPDM, or HDPE, these liners help prevent water from seeping into the ground, ensuring that the pond retains its water. They come in various sizes and thicknesses, allowing for customization based on the pond's dimensions and intended use. Installing a pond liner involves digging a hole, placing the liner in the desired shape, and then filling it with water. Proper installation is crucial to avoid leaks and ensure the longevity of the pond. Additionally, pond liners can support aquatic life and enhance the aesthetic appeal of gardens or landscapes.
