Please help, I desperately need advice. The construction of our new inground fiberglass uniwall/concrete bottom pool has been a nightmare in Cincinnati, OH. We're going on week 6 of the build which has been on the slow train mostly due to weather but somewhat due to work & business ethics. We actually have had a very wet Spring here in Cincinnati. Anyway, today I noticed a tremendous crack in the concrete floor across the entire width of the pool. Keep in mind that the floor was poured a week ago and the pool tile hasn't even been installed yet. Anyway, they applied some concrete crack epoxy and say it will be fine. I question whether or not the bottom was too wet or muddy during the pour but they did it anyway (but I got plenty of pictures and video). Should I question the structural integrity of the pool? Should I get professional legal help? Should I withhold final payment? Or should I just chill out. It's a $40K pool and this is really weighing heavily on me and my wife. Thanks.
