I was wondering if it was normal for cracks to appear in the concrete section on the walls of the deep-end in my new inground vinyl pool project. The concete was poured on Friday and by Sunday there was quite a few cracks in the concrete, some of which are deep and rough, especially on the sides below the steel walls and above the bottom of the pool in the deep end. If some one could let me know if this is an issue or not that would be great.

Thanks
