Rectangle pool liner pad protection starts under your pool—this 12 x 24 ft underlayment cushions the base and helps prevent punctures from rocks, roots, and debris to extend liner life. Made from extra-thick non-woven geotextile fabric, it adds comfort underfoot, supports drainage, and reduces weed growth under above-ground pools. Trim-to-fit design suits many soft-sided and hard-sided pool setups.

Set your above-ground pool up with a protective layer that’s built for real backyards. The dense recycled geotextile underlayment is designed to take the abrasion and pressure that can shorten liner life, while staying easy to handle during installation. Use it under rectangular frames and other compatible pool bases, then trim the edges for a clean fit. Grab yours today and start the season with added protection under every step.
