My pool is approx. 7 months old. The concrete deck has lifted in many areas around the pool about a 1/4" above the water seal. In a few spots the shifting has caused some tiles to buckle and break. I'm wondering how serious an issue this is and how common? Also, typically, what would be the responsibility of the pool maker? Certainly this wouldn't be cause for the concrete deck to be replaced would it?
Thank you in advance for any advice you can give me.
