Like most of the world we have purchased a 12x24 Intex Ultra XTR for the backyard. In an effort to lower the sight line of the pool surface (for safety and aesthetics) I am planning to excavate down a foot on level ground, then install the pool. Does anyone have experience with backfilling the void once the pool is installed? I am going to prep the area with stone dust and I’m considering foam insulation boards on top of that. Can that void then be back filled with sand? I am planning to leave the pool up and winterize it so it will not come down every year.
