The Bestway® Ground Cloth is designed to protect your above ground pool from wear and tear caused by pebbly turf, pointy twigs and other ground debris. Simply place the ground cloth on the spot you plan to set up your pool. Not only do the ground cloths protect the bottom of your pool, but they also offer fantastic protection for your lawn. If water spills over the edge of the pool, it simply accumulates on the ground cloth, saving you from sinking knee deep in sludge when you exit your pool. Bestway ground cloths are also great to use under inflatable hot tubs, play pools and mega water parks. This ground cloth was made for pools (or other items) up to 15 feet in diameter. Protect your pool and your lawn with the Bestway Ground Cloth!
