Pool Cove Peel & Stick 48in for Above Ground Pools All above ground swimming pools need a cove!  Read any pool manufacture's installation instructions and you will find:  "The cove is a vital structural element of your pool."  A cove is needed to keep the weight of the water in the pool liner from causing it to balloon out under the bottom of the pool wall.  Previously, pool cove had to be hand built, in place, using tons of sand or dirt. Liner failures due to cove washout were all too common. Hand formed coves are uneven, with hand or shoe prints, making cleaning difficult. Peel Off backing and affix to wall as shown. Butt pieces up against each other insuring that there are no gaps. Lightly broom sand on top of pool cove. Hose sand down till it is even with bottom of cove Tamp Sand around entire pool bottom. Install Liner as normal. Liner rests tight against cove creating a sealed barrier, keeping moisture from getting between the wall and liner.      Sand and dirt can be washed out leaving a gap and causing excessive strain on the liner that could result in liner failure. A Pool cove becomes part of your pool to seal the space between the wall and the liner and to prevent liner strain. Made from chemically-neutral foam, it helps fight corrosion. It's compatible with all vinyl liners. Eliminates the need for banking of sand, otherwise used to create a sealed barrier between the wall and liner. Accommodates wall stretch to help prevent liner tearing and leaking. Fights corrosion to add years to a pool's life expectancy. Will not erode or freeze; holds its shape indefinitely. Call for pricing
