Cracks In Garage Floor

ETHICS05

I'm sure this has been addressed somewhere already - please direct me if that's the case.

New Construction Spec - home is 5 mos. old - need good solution and technique to fill/fix running crack in garage concrete floor. Crack is less than 1/16" wide. The proper cuts were made in floor after pour both vertically and horizontally. Crack runs parallel about 1 ' above cut the whole width........figures.

Tried putting in some elastomeric concrete caulk and then painted floor with Tuf Top by Flex Bon (after etching). Looked good for awhile, but crack has opened....probably due to more settling.

We're in South Florida.

Thanks for any other ideas.

Sounds like the slab was not sawed deep enough. Also, there may have been a gap in the wire mesh parallel to where the slab was sawed. - Maybe they sawed in the wrong place?

Its not uncommon for concrete to crack someplace besides the cut. Maybe it wasn't deep enough or didn't cut soon enough or several other possibilities. The crack sounds like nothing other than a cosmetic problem, don't know of any surefire way of fixing it,thats just part of concrete work! Like the old saying goes, there are 2 guarantees with concrete, its gonna get hard and its gonna crack! Seriously we do a lot of concrete and try to control the cracking with cuts but sometimes for whatever reason you get a stray crack. Very seldom has anybody ever complained!

i have a crack in my garage floor. Goes the whole length of garage. But its a detached two car garage so im not worried about it. Seeing how it was built probably (not Sure) in late 70's i figure there probably isn't much i can do about it. I did notice back then they didn't put any groves in the concrete like they do now.

I give people a 100% money back guarantee for concrete cracking.

If it doesn't crack, I'll give them all their money back. (Of course you want it to crack in the control cuts)

Thanks Guys!

At least I got a good laugh today reading your replies. That's what I thought, but wanted to make sure.

At least I can now make it a little more humorous in my response to the question when I get another one.

By the way, it was Fiber that we used for the whole slab.
