I hope someone can help me. I posted in the AG area about a liner but no one responded. Guess I was in the wrong area?
Anyway, we have an AG pool, 16 years old, replacing the liner for the first time. The sand is compact and as far as we know, never leaked (washed out) etc. We put black plastic down before the sand (as instructed), but I don't believe up the sides behind the sand cove. We are installing wall foam and moving the skimmer and return due to rust.
I was not planning on taking out the sand cove but just filling in the divots(from feet) on it and the bottom footprints. Why fix something that has done well for 16 years? Nothing has grown up through the sand.
So.... would you still put down foam board over the sand?
