Pool liner pad protection starts with this 15ft round underlayment, built to help prevent punctures and extend liner life for above ground pools. The extra-thick non-woven geotextile cushion shields your liner from rocks, roots, and debris while adding underfoot comfort. Designed as a universal fit, it can be trimmed for soft-sided or hard-sided setups and supports cleaner water by helping block weeds from below.

Set your pool up with a protective layer that’s made for real backyard conditions. This heavy-duty ground cloth underlayment helps reduce friction and wear that can shorten liner lifespan, while its black geotextile construction stays tough season after season. Use it under new installations or when replacing a liner to add cushioning and extra insurance against hidden ground hazards. Choose the 15ft round size for a close fit, then trim as needed for a clean install. Grab yours today and prep your base before filling.
