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.
