Currently undergoing a pool build. At the stage where pebble sheen is about to go in. Pool builder has sent guys a couple times to drain pool out as it had a little water in it each time even with no rain. From what I gather there is a small leak or "weeping willow" as my pool builder calls it in the Gunite. It is still slowly weeping water but has now been covered with some hydraulic cement and the pebble sheen should be going in next week. Even after it's been covered by the hydraulic cement there is still some water slowly weeping through. I don't know much about pools but this doesn't seem right to me. Pool builder is advising pebble sheen will go over and be sealed and I won't have issues. Seems to me this is asking for a leak to develop or something?
The pool was over excavated by 3 feet by accident during excavation. Not sure of any other pertinent info I can provide. Thank you for your help.
