What is above-ground pool cove and why is it necessary?
A cove is needed to keep the weight of the water from causing the pool liner to balloon out under the bottom of the pool wall. Previously, pool cove had to be hand-formed with plenty of sand or dirt. Liner failures due to cove washout were all too common, and corrosion occurs rapidly where metal components at the bottom of the pool come in contact with moisture in the sand or dirt. Hand-formed coves also are uneven, making cleaning difficult.
