Underlayment

This soft, polypropylene 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.
