I know this has probably been asked before but I can't seem to find a definite answer. I'm going to redo the base for my 16' x 48" round Intex Ultra frame pool. I will be using styrofoam and sand as the base.
1. Can the styrofoam be subjected to the weather?
2. Does it need to be covered?
3. Is the below order OK?
Pool Base setup:
1. Tamped level ground.
2. Thin layer of sand for final leveling
3. 1.5" or 2" styrofoam
4. Ground cloth if needed.
