Yankee Pool Liner Pad 18 Ft Round Puncture Proof Above Ground Pool Protector. This pool liner pad sits beneath your pool liner to protect it from damage caused by rocks, roots, grass growth, insects, and general wear. The tear-resistant geotextile material can extend your pool liner's lifespan up to three times longer. It's designed for use under both soft-wall inflatable pools and hard-wall above-ground pools, and works on various surfaces including grass, sand, stone, concrete, and wood decks.
Installation is straightforward: spread the pad on level ground, then place your pool directly on top. For hard-wall pools, install the coves first, add the pad, then the liner.
The pad also adds a comfortable cushioning layer underfoot and helps retain water temperature while preventing erosion beneath the pool. 16.4 x 11.0 x 30.0 inches.
