You seem to be so vocal and possibly just being that only. Have you ever heard of the foundation water test level system? I am sure you have not. Have you ever heard of one side of a foundation, slab falling? I am sure you do not? Have you ever heard of one side of a foundation being of different type of dirt or near a neighbor's sprinkling system being more or less unstable than the other side? I am sure that this sentence is too long for you.
your dog does not hunt my friend.
Steve Ps, I disagree with all your verbage and lumps of it. If you are in the business, I now know why so many foundations, slabs are in trouble.
