There’s no impact if your driveway heaves other than cosmetic. If your garage heaves if could have some major issues. Especially if it doesn’t displace evenly throughout. On the design. I assume you are referring to footer interchangeably with what I’m calling chain wall. You are probably on the right path. Just remember there is such a thing as too much rebar. The concrete code has both a Amin and Amax for steel area in a slab. |

With a floating slab, you shouldn’t have any issues unless you develop a void or something. That would likely come from poor construction and knowing you, you probably supervised so they wouldn’t do anything stupid. |
