Protect your pool before damage starts. This 450GSM extra-heavy pool liner pad is designed to sit between your above-ground pool liner and the ground, creating a dense protective layer against rocks, roots, weeds, grass, sand, gravel, and concrete surfaces. The oversized 16.5' x 33' rectangular design offers wide coverage for large above-ground pools, while the one-piece seamless construction helps eliminate weak spots caused by gaps or overlapping pads.
Beyond basic protection, the thick geotextile fabric adds a smoother, more comfortable base underfoot, making every swim feel better for kids, families, and everyday backyard use. Durable, trim-to-fit, and easy to install, this pool ground mat helps reduce liner wear and supports longer-lasting pool performance season after season.
