Hello all, got a crack that goes across my entire garage floor. can I just put some concrete in it? I've got a bag of concrete that's just sitting in my garage. Thanks

Woody.... give us a picture. Doubt you are going to be able to put CONCRETE in a crack.

(Normally use a concrete patcher or concrete caulk.

You can use a Micro injection grout.
www.cathedralstone.com
Depending on crack size you can use Jahn M30 or Jahn M40 both can be applied using the gravity method.
These type of grouts will be a higher cost than any other type of filling materials but will correct the problem providing it is not a working crack.

ist, define 'repair' as there's generally no disguising/camouflaging cracks,,, is it static (same size year 'round) OR dynamic (changes width relative to temperature ? some bridging plaster would easily show which,,, proper methods/materials differ,,, IF its static, you can use previously mentioned mortars,,, IF dynamic, use backer rod & sealant,,, w/o pictures/dimensions, wouldn't suggest concrete
certainly would be a BIG + if you posted location too ( that means in which part of the world your garage is located

you have more of an issue than just a 'crack',,, suggest you square the area, chop it out, & replace w/concrete instead of just trying to seal/fill a crack instead of my previous post's advice
ps -this advice stands for wherever YOUR geographic 'where' is located

Looks like it might be close to the door; are you getting some settling at the edge of the garage, maybe?
It looks like whoever owned the house before my purchase had tried to repaired it. never paid any attention to it until I recently had to take my bike out and almost tripped on the piece of loose concrete. the stuff that you see is the rest of the loose stuff that I was able to pry out of the crack.

'tried to repaired it' how ? by using something that's solid ? injection grout's good in its place but we wouldn't pick it here,,, think you're far beyond its capabilities,, can't 'repair' crks properly w/o knowing if its static or dynamic,,, ( sound familiar, no ? ) pay attn to posts & learn sumthin', grasshopper :smile: in the meantime, when you walk, pick up your feet
