Underlay is used to protect pond liner from rocks, roots, and other sharp objects that may damage the liner. The underlay is lightweight, spreads easily, and has a non-slippery surface, making installation quick and easy. The soft, non-woven geotextile made from polypropylene also allows for any gasses to escape properly, rather than becoming trapped beneath the liner.
  • 8 oz. pond underlay
  • Available in 6' and 15' width
