Quick question. We poured our collar yesterday, in the process a wall moved midway down the long wall. Seems like the concrete pulled it back. When we pulled a string line, it was back at the top and bottom about a 1/4 or so". My concrete guy (family) said he has seen this before and its not a big deal. We are doing cantilever pavers for coping, so he said it will not be noticeable.
Are there any structural concerns?
