We finished and filled our new in ground vinyl liner pool just under one year ago. What we have noticed in several spots where the poolcrete appears to have sunk and cracked below the liner. One spot in particular looks as though the liner is being stretched and could tear.
I've read that pool bottoms will move and crack over time, but a year seems too soon for this to happen.
I'm in the Austin, TX area, and 90% of what was removed when digging the pool was solid limestone. The only dirt that is there to settle is what was brought in to form the base.
The builder is coming out tomorrow to look at it. Any thoughts or suggestions?
