Hello, I had a pool installed this summer.

It is an inground, galvanized steel walls, with Poolcrete floor and vinyl liner. After the pool was filled with water we noticed that the floor and curbs were not smooth. The poolcrete appears to not have adhered to the previous batchs of poolcrete. At each pour line there is an indentation line and in some areas the poolcrete shifts or moves when you step on it. The pool installer has offered to remove the water and liner this fall to patch the seems. I'm looking for some advise... Can poolcrete be patched and hold up as good as one pour? Will I ever get a smooth finish? Do I need to have all the pool crete removed and repour the bad sections? Would the installer notice this before installing the liner? Should I have to pay to fill the pool back up? Will changes to the depth affect the liner being reinstalled?

Appreciate any help with this poolcrete installation mess!
