U.S. Pool Supply 18' Round Ground Shield Pool Liner Pad — Heavy-Duty 220g Geotextile, Extra-Thick Cushioning

U.S. Pool Supply Ground Shield 18' round pool liner pad is an extra-thick, heavy-duty geotextile barrier that protects above-ground pool liners from punctures, abrasions, weeds, and ground irregularities while adding cushioning underfoot.

Installing an above-ground pool means protecting the liner from sharp rocks, roots, glass, and uneven ground. The 18-foot Ground Shield pad from U.S. Pool Supply is made from 220-gram non-woven geotextile fabric designed to sit between your liner and the soil, creating a stable, weed-resistant surface that extends liner life and improves comfort. It trims easily for a custom fit and works with soft- or hard-sided pools.

How does this pad prevent punctures and wear to my pool liner?

The pad delivers a physical barrier that spreads pressure and keeps sharp objects from contacting the liner directly. Its extra-thick, heavy-duty construction resists tears and abrasion, lowering the chance of sudden punctures and slow wear.

• 220-gram non-woven geotextile fabric resists rips and abrasions
• Extra-thick layer cushions against rocks, roots, and debris
• Reduces friction between liner and ground to limit long-term wear

Will this pad make installation simpler and fit my pool shape?

Yes — place the circular pad on leveled ground before setting the pool and trim with a utility knife for precise edges. The 18-foot round size is made for common round above-ground pools but can be cut to match different diameters or to accommodate fittings and return lines.

• Lay pad slightly beyond pool edge for full coverage
• Trim easily with standard cutting tools for a tailored fit
• Compatible with soft-sided and hard-sided above-ground pools

Does the Ground Shield help with weeds and pool comfort?

The geotextile material acts as a weed barrier that prevents plants from pushing through into the pool area, helping reduce debris and maintenance. It also adds a subtle cushioning underfoot, making the pool floor more comfortable to walk on and less abrasive to the liner.

• Prevents weeds from growing through to the liner
• Keeps leaves and soil from migrating into the pool base
• Provides a thin, comfortable underlayer for swimmers

How durable is the pad and what warranty does U.S. Pool Supply offer?

The pad is manufactured for long-lasting outdoor use, built from heavy-duty material meant to withstand seasonal stresses. U.S. Pool Supply supports the Ground Shield with a 2-year limited warranty covering pool liner pad replacement, giving added confidence in its durability.

• Heavy-duty, extra-thick construction for extended service life
