cracks in concrete

[Jeffski]

They used a product similiar to concrete on our pool, I think it was called gunite(?). Anyway, after they poured it we had to wait a few days for our liner to come in and it rained hard during that time. The concrete product cracked just as you're describing. The pool guys spent a whole day repairing spots.

Needless to say they were pretty ticked at the pool company (they were subcontractors) for not having the liner ready to be installed as soon as the pool bottom was prepped.

This will be a major issue if not repaired because the liner will be placed over jagged edges and could rip, plus it won't be nice and smooth and you will see the cracks or at least the uneven areas.

I'm sure they will fix this so you probably don't need to worry...unless of course they don't fix it.

It rained after they poured our pool as well. The weather report said zero percent chance the day before. Go figure. Hopefully you are right.
Thanks

I'm not sure if rain alone would cause that. After our concrete pool was shot with shotcrete we were told to leave the sprinkler in it going for 3 to 4 days. We had no cracking at all.

It's a totally different product for a liner pool.

Our vinyl pool has a vermiculite bottom - more forgiving (and gentler on the liner) than straight concrete, way sturdier than sand. Installed in 1982, liner was replaced in 2004 - and there were no cracks in the vermiculite to be repaired after all that time. We had 2 divots in the shallow end they patched up - one caused by the ground settling, the other from a kid jumping into the shallow end (another good reason to only jump into the deep end).

You need to have the contractor fix that immediately - it will definitely show under the liner, probably will damage it in time and if you are getting a light, it will stick out like a sore thumb when lit up.
