Garage Floor

I inspected a home friday that was on a basement built into a slight hill. The foundation all around the home looked good and tight, one MINOR crack in the top corner. However, the garage floor looks like it has sank about 3 inches. One quarter of the garage floor has a crack in the middle and it sank down then raises back up in the middle. I think it is nothing besides poor workmanship on the part of whoever did the dozer work with the fill and on the garage floor installer. The steps from the garage to the home had not shifted, the foundation where the garage door meets the house had not shifted, etc. Just the one portion of the garage floor. Any ideas?

I believe you are correct on the poor quality of the final grade, but I have found the obvious dozer operator may or not be to blame. The concrete flatwork crew is inevitably the responsible party; the exception is if the slab shows signs of water that may have undermined it. The concrete crew that did the flat work may have also had the job of placing and grading gravel with a Bobcat or similar equipment and failed to fill it and compact properly. Or even placed unpacked dirt into the void area due to lack of available gravel at the job site.

Also the building prints often call for piers which in many cases are a correctly placed pour of concrete, this may also aid in the reason that it distinctly stopped dropping at a specific area.

No I am not a card carrying member of dozers are us, this just happens to be some unpleasant learning?s. ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)

Let?s see what others have to say.

Dave -

I agree with Michael. It's probably due to bad fill being used, or non-compacted fill, or a combination of both. Builders for decades have tried to save money by using dirt fill, instead of going to crushed stone. It's definitely not the area to try to save money. I'm surprised the original homeowner didn't go back against the builder to get it corrected.
