The Liner Life Pre-Cut Pool Liner Pad is specifically designed to cushion and protect the bottom of your aboveground pool. Pre-cut for easy installation, this swimming pool padding is manufactured to fit most popular pool sizes, eliminating the need to measure, cut, and tape as one would with foam padding. Made of durable, high-quality polyester geotextile material, the Liner Life liner pad for swimming pools will help prevent grass, roots, rocks, or other sharp objects from damaging your pool’s liner. Plus, it will not only keep your pool protected, but it also improves swimmer comfort. Along with the added layer of cushioning, this pool liner pad prevents footprints from forming in the sand base beneath the pool liner for a consistently smooth swim. This Liner Life Pre-Cut Pool Liner Pad is perfectly sized to fit your 12’ x 24’ rectangle pool.
