So I'm thinking that when I set up my pool for the first time that I want to put down some protection for the bottom and either Extruded polystyrene (XPS) rigid foam or Expanded polystyrene (EPS) for insulation, smooth bottom and comfort.
Once the ground is level and ready to go, I am considering a Gorilla Pad for protection from rocks and growing things.
Then 2 inches of Extruded polystyrene cut to size and taped together, then the pool liner.
Question, I'm guessing I don't want to put the pavers for the support posts on top of the foam but rather sink them level with the ground. If I do that and then put down 2 " of foam, I am loosing 2 " of pool water and depth. Probably not a good thing, right? To compensate, if I set 2" pavers on the ground then put down the foam and cut around the pavers and extend the foam all the way to the edge of the pool and also fill with some dirt around the outside... would that work? Other, more difficult option would be to sink the pavers level with the ground then excavate 2" of dirt to drop the foam into making the top of the foam level with the pavers and surrounding ground.
Anybody do any of these options or have other suggestions?
