Underlayment

This soft, polyethylene fabric will last 20+ years under your liner. It is a 3-dimensional underlayment that allows gas to escape. It has a non-slippery surface and provides protection for the liner from rocks and other sharp objects, spreads easily, and saves time compared to using newspaper or sand. This is a non-woven, needle-punched Geotextile.
