Looks like Lighthouse is going to have to come out and do some work... Like jack hammering up all the surface concrete they poured. I just hope it doesn't look like that under the garage floor. We haven't even started driving on the apron or garage floor yet, but I suspect they would crack pretty badly if we did...
Would love any advise people would have on alternatives and if they would be sufficient or not. I am sure LH will try to fix this as cheaply as possible. Or maybe it will be the responsibility of the sub that poured the concrete. Not sure.
Honestly....doesn't look like the concrete guy caused this. Looks like water/rain washed out the sub-grade after the concrete was poured. Looks like a drainage, lack of grass or ground cover. After the sub-grade washed away the concrete cracked. Also, ALL concrete cracks, hairline and narrow cracks are common and structurally insignificant.
