When i had my garage built we had to build up my back yard area where it was to be about 24".my garage is 24'x26'.my drive is on about 20 ' of the fill then the rest is the garage. the garage company poured a slab with raised edgesa all the way around,except doorways,of course. there is no suppost at all in the floor as near as anyone can tell.i wasn't here to see it built.that was my mistake.anyway i now have a crack about an inch or so wide clear across the garage and it divides off and goes two ways..the floor also raises up about half an inch on the west end of the garage..I did not realize that they were not putting any support in this floor when it was built. it was also not cut.. merrill lynch would not be bullish on this garage if you get my drift.
Is there anything i can do to this floor to help it out from it getting worse. can i clean it out any pour more concrete or will that do any good.thanks for any help.

 

Hi,

Last week I cleaned out my garage in my new home and found a similar huge crack in the floor. My plan was to clean it out, drive a bunch of screws into the sides (it is big enough where I think I can angle them in) and then fill it up with epoxy. But given that it is about 10feet long, it is not going to be pretty. Anyone want to comment if this is a good plan?

Thanks!
