You need a consult with a foundation expert as well as a soils engineer. This is not a Homeowner DIY, you need licensed professionals for this job.

I agree with Naomie. The only thing I’ll add is tell you about how it is fixed. A company will come in with hollow core bits. They are fairly large (3-4 inches). They’ll drill a series of holes and insert a pressure hose into them. The hose pumps in a fairly loose mix of concrete which raises the slab up even with the others.

So, I'm in Michigan, would you have any idea of aprox what this would cost?
Thank you both, Deborah

  Google or flip through the yellow pages and make a few calls to find out. A consult is just for them to come out and take a look and offer options or recommendations and possible testing. Generally a flat fee. My best guess is $200 each for a consult. I am in CA and everything is more expensive here and they go by zip code. Expensive neighborhood the price goes up, less desirable area a bit less. Anything they recommend or suggest, they will provide a fee schedule.
