We live in Iowa and would like to bury an above ground pool other than doughboy. We cannot afford too much as our budget is under 5K. Has anyone buried a pool at least 2ft and had success for 5-10+ years? We have a quote on a 27' Garden leisure for $3,500. I was hoping with some applied protectant to the outside walls/beams we could make it work. Backfill with soil?
