21ft Round Pool Liner Pad, Geotextile Mat Puncture Guard

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.

• Prevents punctures by buffering your liner from rocks, glass, roots, and uneven ground.


• Delivers extra cushioning for a more comfortable feel underfoot inside the pool.


• Blocks weeds to help reduce debris and keep the pool area cleaner over the season.


• Installs fast with a trim-to-fit design for soft-sided and hard-sided above-ground pools.


• Supports drainage with geotextile structure to help avoid trapped water beneath the liner.

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.
