New in ground pool under construction. The gunite was shot back in Oct. and we have experienced several delays since then.

The issue we have now is a crack that has formed in the bottom of the pool at one end. Standing water had been covering the crack location until the plastering crew completed their prep work. As the pool dried out, we noticed a line (the crack) that stayed wet. It has been over a week now and the crack is still wet.

The question we have is, should we be concerned or not? The PB says it is nothing to worry about. Your thoughts and opinions would be appreciated.

Welcome to TFP!

It isn't a structural problem but it is likely that the plaster will crack there in the future if the gunite shell is allowed to move in the future. With the black clay soil we have it is important to maintain even soil moisture levels at all times. We've had a few cracks in the plaster over the years. One leaked from 2012. All were repaired by the PB using pool putty that cures u derwater. The crack that leaked hasn't leaked since. We installed a micro irrigation system with a hose timer around the pool and run it 1 to 3 times per day for 10 to 20 minutes to maintain soil moisture. It is during drought or winter when the soil contracts and lets the shell flex.
 
Thanks for the feedback, pooldv. When digging the pool, the PB found lots of clay, not the black gumbo, but regular clay. We went ahead and paid to have soil stabilizing injections done for the pool and the deck. We are counting on that to keep the pool and deck from cracking, or at least we will have done everything we could have.

Is there any reason to pay a Structural Engineer to come take a look? Where would I find one??

Thanks!

Have a structural engineer come look before you plaster. Do you have pictures of the rebar stage? Were there structural plans prepared by an engineer?

Tell the PB that this is best dealt with now before plaster. That crack is long and significant. It could cause issues with plaster. So it's best to get a structural engineer who specializes in pools analyze and make some recommendations.
