350G/M² Double-Density Geotextile Pool Liner Pad — 18 Ft Round, Extra-Thick Puncture-Resistant Underlay for Above Ground Pools

HEAVY-DUTY 350G/M² GEOTEXTILE: Constructed from black industrial geotextile with a double-density weave, this pad is upgraded to 350G/M²—twice the density of typical 200g pool liner pads on the market. PRE-CUT 18 Ft ROUND — READY TO USE: The mat arrives pre-cut to an 18 Ft round shape. Simply lay the pad on level ground before setting up a soft-wall pool. For hard-wall pools, install the hole first, place the pad in the bottom, then set and cover the pool. NO CENTER SEAM FOR COMFORT: The single-piece construction eliminates a central seam, creating a smooth, cushioned buffer between the pool floor and the ground for a more comfortable feel underfoot. PROTECTS AND EXTENDS YOUR LINER: This extra-thick pool bottom mat serves as a protective layer between the ground and your pool liner—puncture resistant to reduce damage, extend the liner's lifespan, and help avoid costly replacements. VERSATILE SURFACE COMPATIBILITY: Suitable for installation over grass, sand, stone, wood, cement and other yard surfaces. Also works as a pad for indoor hot tubs or as a vapor barrier.
