Mudjacking leading to significant shift

[ZeroSeq]

Hello,

Two years ago, I had a part of the slab of my house hydraulically jacked based on a recommendation of my contractor who was constructing a new bathroom. The following year, we had a significant amount of rain, resulting in a raising of the slab by over 2".

Aside from the obvious aesthetic fixes (repair drywall), would any structural engineer here be concerned about potential compromise in the structural integrity of the wood frame?

I'm just looking to get a feel for this problem before I shell out the ~$800-1k to bring an engineer in.

It's exactly reasons like this that I'm hesitant to raise sunken on grade slabs after a couple years of little precipitation. Long term the earth balances it out, so when we have a couple of wet years, everything starts to rebound.

Technically speaking there is a point at which a lot of heaving can cause structural issues. However, that would a substantial amount of movement required for that to happen. In your case, I wouldn't be as concerned.

How low was it when it was slab-jacked?
