Hey everyone..so we are putting our Intex pool back up this season the proper way, level and with no creases, and I would like to do foam board underneath. I searched forms up and down for the last week and can't decide between half inch or 1 inch board. I did some research and realize the pink board in both sizes has the same compression rating of 15 psi. It's only when you get up to the 2 inch board that the compression rating increases the 25 psi. The pool were putting up is an 22 by 52 Intex ultra frame and i just want to make sure the half inch board will be okay before purchasing. I went on Home Depot's site and can't find 3/4 inch board.
Any input would be helpful.
