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. Corrosion occurred rapidly where metal components, at the bottom of the pool, came in contact with moisture in the sand or dirt. Hand formed coves are uneven making cleaning difficult.
Pool cove is a 4 inch tall by 3 inch across the base preformed cove made from chemically neutral closed Ethafoam, and is safe for use with all pool liners. Lightweight and easy to handle, comes in 48 inch long sections that bend easily without breaking and are compatible with all pool brands.
