Our new ig vinyl liner pool was backfilled with the dirt they removed. They actually built it up a few feet so the pool is somewhat elevated - though I'm not really sure why since we have some slope but it's really not that much at all. Then they brought in a bobcat, pushed the dirt up to the level of the walls, put down rebar and pliable baseboard (forms) and poured the concrete. No compacting or ground prep other than the rebar, lying on the ground (not elevated) and forms. A few weeks later we have four serious cracks that are apparently completely through the deck. It appears to me that the weight of the stone waterfall caused the deck to crack on either side in approximately the middle of the pool. The builder saw the cracks and said, "we better keep an eye on that," or something to that effect.


We're about 65 days in to this. The pool is filled and we are using it, but one side of the deck has an approximate 3' drop-off. The builder told us a while back he was going to bring in some dirt level it up a little. We're also waiting on a lot of other things he hasn't finished, but...
