U.S. Pool Supply 27' Round Ground Shield Pool Liner Pad — Heavy-Duty 220g Cushioned Underlayment

The U.S. Pool Supply Ground Shield 27' round liner pad is an extra-thick, heavy-duty geotextile underlayment that protects above-ground pool liners from punctures, abrasions, weeds, and ground debris while adding a cushioned footing.

Before you install an above-ground pool liner, the surface between the liner and the earth matters. This 27-foot Ground Shield pad is designed to sit under round pools and create a smooth, protective barrier that reduces liner wear, keeps small sharp objects from causing tears, and stops weeds from pushing up through the pool floor. Made from 220-gram non-woven geotextile fabric, it balances durability with ease of handling so you can trim and position it without specialized tools.

How does this pad prevent liner damage?

The Ground Shield forms a continuous layer that separates the pool liner from rocks, roots, and other sharp items in the soil. Its heavy-duty, extra-thick construction absorbs point pressure and minimizes friction that can cause pinholes or rips in the liner over time. By reducing direct contact with the ground, the pad helps extend the liner’s usable life.

• Extra-thick 220 g non-woven fabric cushions against sharp objects.
• Covers the pool footprint and can be trimmed for a precise fit.
• Low-friction surface reduces abrasion between liner and soil.

Is the pad easy to install for a DIY pool project?

Yes — the Ground Shield is intended for straightforward do-it-yourself installation. Lay it on leveled ground so it extends slightly beyond the pool’s edge, and trim with a utility knife as needed to match your pool shape. It works with both soft-sided and hard-sided above-ground pools, simplifying the prep stage without special adhesives or tools.

• Unroll and position on leveled ground; trim with a utility knife.
• Leave a small overlap beyond the pool wall for full coverage.
• Compatible with soft-sided and hard-sided above-ground pools.

Will this pad help keep my pool cleaner and safer to walk on?

The geotextile fabric also acts as a weed barrier so plant growth won’t penetrate into the pool area, reducing organic debris and maintenance. The extra-thick layer adds a modest cushioning underfoot, improving barefoot comfort on the pool floor and lowering the chance of small scrapes from the underlying ground. While not a substitute for a pool cover or routine cleaning, it helps maintain a tidier, more user-friendly swim surface.

• Weed-barrier properties reduce plants and root intrusion.
• Thin cushioning improves comfort for feet in the pool.
• Helps keep dirt and debris from working up through the bottom.

Who is this product for? Installers, homeowners, and rental-property managers who want to protect an above-ground pool liner and reduce long-term maintenance costs will find this Ground Shield pad useful. It’s especially practical if you need a robust, easy-to-trim underlayment for a 27' round pool footprint and prefer a product that offers both physical protection and a weed barrier. Backed by U.S. Pool Supply’s 2-year limited warranty, it’s a sensible choice for anyone looking to extend liner life without complex installation.
