Hi all I stumbled across this site while looking for a solution to my garage floor cracks. Long story short I’m a fairly new home owner. Finally got a decent tax return so I’m trying to really build my garage the way I want it. I’m bumping it out the back and considering putting a lift in as well. But I have some cracks and I’m not sure if they are repairable or if I need to rip everything up and pour a new slab.

Without seeing the whole floor, based on those pics I would rip it out and start new. Need some more info. How old is the slab. How big is it. It almost looks like the sub surface is failing and causing the floor to crack. If it is isolated to a small area, saw cutting out the bad area and putting new in at that point would be ok as well. If you want a lift, best bet would be to take it all out, prep the substrate well, and pour new.

The only fix for that is a jackhammer and a new slab.

I'm with readhead on this one. Sorry but there is no way to properly fix that slab. If you decide to proceed with removal and replacement, pay some attention to the base below. Either your concrete or the soils below are defective. Good luck.

I would put a Mid rise on that. Not a two post

Hard to say in pictures, but it likes like the cracks have moved vertically leading me to believe differential settlement. Need to tear our part if not all, remediate the sun grade bearing issue and replace. I wouldn’t put a 4 post on that let alone a 2 post....

Welcome to the forum.
I am in agreement, rip out the concrete and start over.
Is the garage itself in good condition, or is there issues with it? If the garage needs a lot of repair work, it may be more advantageous to tear the whole thing down and build it exactly the way you want it.

Thanks for the quick reply‘s I really don’t have any information because I bought the house as a foreclosure from the bank. I do know that the house was built in the late 50s so I’m assuming the garage slab is relatively close to that as well. As far as structurally the garage is fine it just needs a new roof. Looks like I’ll be ripping this all up and putting a whole new slab in.

It's time to see the concrete man.

Hire a bobcat with a hammer attachment and bucket. A guy with experience can make short work of it. He can then bucket it into a waiting truck. Most guys have somewhere to dispose that won’t have landfill costs involved, just the trucking. Then you are good to go and proceed with whatever your needs are. Like previously stated pay attention to your sub grade to decide if it’s acceptable

Rip it out and consider getting a Geo report on your soil. follow the Geo recommendations which will probably be digging out 6" of native and bringing in 6" of what we call type II base material which is sand and rock that can be compacted. Why I was at it I would scratch in a couple of 4' x 4' x 12" thick footings with reinforcement for the car lift.
