I recently had a foundation repair crew lift a corner of my slab about 0.5". In the process, they somehow cracked my garabe slab (spiderweb cracks). They’re denying responsibility and their engineer said it was nothing to worry about. Is there anything I should do now? Otherwise, I plan to wait for Spring after seeing if winter affects it.

    There’s an old adage that I’ve heard multiple civil engineers tell me.

    There are only two kinds of concrete. Concrete that has cracked, and concrete that is about to crack.
    Your slabs having zero cracks until now is more impressive than it getting cracked NGL.

    As long as the slab does not begin to separate (different pieces sink and leave ledges) its probably not worth pursuing. I’d throw sealant over the top to keep it from flaking and call it.

    Do you have before/after photos to show they caused the cracks?

    I’d get an independent assessment of the damage. It’s possible it’s just cosmetic like their engineer said.

    If the damage is limited to a small area you could try to have that portion of the slab removed and repoured.

      I have only after, because they assured me it wouldn’t happen. But they agree the cracks, which are all over, probably happened due to their work.

    Concrete cracks. As long as it’s not moving more I wouldn’t worry about it.

    You sound like you’d want a garage floor sealant to hide imperfections. I don’t think I would have even fixed a slab that was off-level by only a 1/2”

      I’d say not only is that not worth fixing, but to have the front 1/2" lower than the back would be ideal to get rain and melted ice to flow out of the garage rather than pooling. That assumes it isn’t below the driveway, though, because in that case it wouldn’t do any good (and if you have a heated garage will lead to your garage door freezing to the floor… ask how I know).

      It was off by more than an inch. They adjusted it up about 1/2" to get it back within accepted levels.

      We’re thinking about selling the house, so I don’t want to draw attention to the cracks, but I also don’t want them torpedoing a sale

        Check out 10 other garages of homes for sale in your area and I bet more than half have cracks.

    I would use cement patch. It is sold by the bucket at any hardware store.

    Or if you want to redo the whole thing use an epoxy coating.
