Pool liner pad protection starts with a tough underlayment that cushions your base and helps prevent punctures from rocks, roots, and debris. This 21ft round pool liner pad uses extra-thick non-woven geotextile fabric to reduce liner wear, add underfoot comfort, and support cleaner water by blocking weeds beneath above-ground pools. Built for quick setup and easy trimming, it’s a practical upgrade before you fill.

Protecting your liner is easier than replacing it. Place this round pool ground cloth under your above-ground pool to add a durable barrier between the liner and the ground, helping reduce friction, wear, and surprise punctures. The recycled geotextile underlayment is designed for long-lasting use and straightforward placement—measure, position, and trim as needed for a clean fit. Set your base right before the season starts; grab yours today and prep your pool with confidence.
