I've seen 2 of these attempts, and neither of them worked (in the long 5-7yrs run). The panals are there to hold the liner, not to keep the pool's shape. The previous post was right in that you'd need at least 5' of backfill around it. Perhaps a few more steps are in order so that you have an inground pool. If you want an A/G pool, put one up and surround it with a deck, but trying to hybrid it won't last
