Ground water during pool build

[PSUmech]

Hi, new member here. My pool install is getting underway and I have some ground water questions. When they dug the pool some ground water was encountered in the deep end( 8’ deep pool). It would settle at about 10” or so of water. We kept it pumped out so that it would lead to any wall erosion before the shell was shot.

The shell (gunite) has now been shot and as we are waiting for curing the ground water (~10”) has come back through the open holes in the bottom of the shell. I’ll talk with the pool builder, but is this a concern?

I would not be concerned for the pool. Consider it extra water for curing.

Mine was similar, but I had more depth of water intrusion than you. I kept it pumped, as you, to no lose walls. Shotcrete, with 2 weep holes, continued to get water. Pebble finish was done months later, shell was pumped at the start, weep holes sealed with hydraulic cement, then pebble applied. To date, about a year, no issues.

Keep allowing the ground water to release from the back side of the shell.

Thanks for all the feedback. Seems like it might not be a problem. I believe the pool builder is installing relief valves in the bottom as well in cases of abnormal pressure build later.

Make sure that they control the ground water or the pool can pop out of the ground.
