Pond Underlayment – Precut

Pond Underlayment rolls are used to protect the pond and water feature liner from rocks, roots, and other hard objects in the excavated soil that may damage the liner. The underlayment is lightweight, spreads easily, and has a non-slippery surface, making installation quick and easy. The soft geotextile is made from polypropylene and allows gases to escape properly, rather than becoming trapped beneath the liner.
