Re: New driveway lifting and settling
It's a bit too late for this advice now, but it may help others in the future. Any time you hire a contractor to install concrete, the contract should state what the acceptable amount of cracking and movement is.
Please understand that ALL concrete will crack to some degree, and some settling is to be expected. Usually, hairline cracks will not be covered under warranty. Cracks that separate over a certain amount (say, 1/8") or where there is vertical displacement should be addressed in the contract.
In my layman's opinion, 1-1/2" is NOT normal. Imagine how awful the freeway would be with "normal" 1-1/2" displacement. However, I would not expect to demand replacement for displacement of less than 1/4" on a driveway slab.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
