Hi avc130,
The hole was probably fine, but the whole dig had groundwater problems. They put a lot of stone at the bottom, especially at the deep end and had pumps running constantly. Part of it was that we're only a half mile from the Delaware Bay and about 8 miles from the Atlantic, so the groundwater rises and falls with the tide. When they put the first pool in the hole they told us to put a couple of feet of water in it to hold it in place, so we ran two garden hoses on full, but that obviously wasn't enough. We got a big storm that night, and the next morning the pool had shifted in the hole. The PB tried to move it back by lifting up on the deep end with his excavator, and shortly after that they came to us and told us we had a crack in the deep end.
Was the crack caused by the original shifting or by moving it with the machine? We'll never know and if the PB knows, he ain't tellin'. But it turned out to be a blessing in disguise. The replacement pool is better quality (Riviera brand as opposed to Blue Hawaiian), darker in color, and doesn't have steps all across the shallow end so we can more easily swim laps. It did delay the job by at least a week, but we'll end up with a better pool (for no extra cost!).
