Heavy Duty Underlay 250 GSM Boxed

Aquascape Heavy Duty Underlay 250 GSM Boxed is used to protect pond liner from rocks, roots, and other sharp objects that may damage the liner. The underlayment 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 gases to escape properly, rather than becoming trapped beneath the liner.
