I am working on clearing the sod and leveling the ground (which is back breaking work!) for setting up the pool. I am planning to use rigid foam insulation along with a foam cove and wall foam under the liner. I am wondering if putting down a sheet of 6 mil plastic first and then the rigid insulation is sufficient or if I need something else under the foam insulation? Any suggestions?
Also, is there a difference between the different pool cove products being sold. Most places don't tell you much about it. Thanks!
