Shtocrete Crack cause for concern?

[Titan7]

I have stopped posting on pool progress as I appear to be "Capt. Buzzkill", but it's just been a nightmare. So one more question, shotcrete was done Dec. 15 of last year, the 28 day test result showed it was at 6,028 PSI.

Our 2nd pool deck was finished 2 weeks ago (long story) and now I am waiting on a custom iron gate. Plaster should be done at some point hopefully this year

So I am out cleaning all the debris out of the pool when I notice this crack. It's in the middle of the pool on the bottom, it does not run in in a straight line but basically runs across the entire bottom of the pool. this is in the transition from deep end to shallow end. Normal, should I be concerned?

I just wanted to see what you guys thought, I did advise the PB. epoxy? leave it?

I guess I just want it to hold for few years as we are most likely moving after we get this finally done.

Edit: its small, using a feeler gauge its about 1/32- 1/64" or less in places

Hairline cracks are very typical in gunite/Shotcrete. That appears to be a shrinkage crack which shouldn't be of too much concern and can easily be filled.

Your PB will deal with that as part of the plaster process.

You're moving after the pool is finished??

Believe we will be moving to Frisco, TX in the next couple years, I can transfer out there as can my wife. I visited the office last week, $$ goes a LOOOONNNNGGGG way out there.

Thanks for the info, PB did get back with me as said it was shrinkage.
