Ground Shield 21-Foot Round Heavy Duty Pool Liner Pad - Protects Liner

In this review the Ground Shield 21-foot round pool liner pad is evaluated for homeowners who want a simple, low-cost way to protect an above-ground pool liner. The bottom line: this extra-thick, 220-gram non-woven geotextile pad provides a reliable barrier against rocks, roots and other sharp objects and adds a thin cushioning underfoot, so it is best for anyone installing or replacing a liner who wants to reduce puncture risk and extend liner life without complicated preparation.

Key Features

• Heavy-duty protection: The extra-thick fabric shields your pool liner from punctures, tears and abrasions caused by rocks, glass and roots, reducing the likelihood of costly liner replacement.
• 220-gram non-woven fabric: The durable geotextile material is designed to resist wear and provide a long-lasting barrier between soil and liner.
• Weed barrier: The material helps prevent weeds from growing through into the pool, keeping water cleaner and reducing maintenance.
• Easy installation: The pad simply lays on level ground and can be trimmed with a utility knife for a custom fit around round, oval or rectangle pools.
• Cushioning underfoot: The pad adds a thin layer of comfort to walk on, improving the feel inside the pool while still sitting low beneath the liner.
• Warranty support: A 2-year limited warranty covers pool liner pad replacement, offering added confidence in purchase.

Who It's For

The Ground Shield pad is ideal for above-ground pool owners who want straightforward, functional protection for a new or replacement liner, particularly where ground contains rocks, roots or other debris that could puncture a liner. It suits both soft-sided and hard-sided pools and users who prefer an easy, no-fuss installation.

Customers seeking heavy foam padding or a thermal insulating underlay should look elsewhere; this product is a protective geotextile pad that provides thin cushioning and weed suppression rather than significant shock absorption or insulation.
