We were talking yesterday at the office and the topic came up of what is the reasonable amount of tolerance for a residential slab as far as flatness? Seems like when I was a superintendent for a company years ago, they said it could vary up to 1" over the entire slab, and no more than 1/2" in any 10, and they considered that "flat", which seems pretty loose to me.
Is there some general standard that I'm not aware of? I know generally there is some variation across a slab even with a good Concrete crew, but what is an acceptable amount?
Thx.
