Simply peel the easy-strip from the adhesive and apply to the bottom of the pool wall and permanently do away with the need for a sand cove. Rest assured of years of extended life expectancy of the pool liner.
Why do I Need Pool Cove?
The red arrows represent the force of water pushing against the Earth and the pool wall. The point where these two forces meet is indicated by the purple arrow. At this point, the net force is of such magnitude that it will force your liner under your pool wall and can cause it to rupture. A cove disperses those forces so that the liner will not slip under the wall.
