Armor Shield Round Floor Pad for Above-Ground Swimming Pools — 16-Foot Round Liner Protector

Made from polypropylene geotextile, this 16-foot round Armor Shield floor pad forms a durable barrier between a vinyl pool liner and the soil or sand base. It guards the liner against cuts and punctures from rocks, roots, grass and even glass, while also helping to lessen convective heat loss. The fabric creates a cushioned, comfortable surface for tired feet and is simple to install — just lay the pad on top of the prepared soil or sand bed before setting the vinyl liner.
