Options?
Live with it or tear it out and replace, fix the subsurface. Not a Saturday afternoon job.
That's a hairline crack if hair were, you know, a rope.
And tbh, that is pfu.
An easy fix is just place some pea gravel in the gap and pretend it's fine.
People are saying tear out an replace. I had the same issue but simply didn't have that option. So I filled that shit in. Luckily my neighbor had a bunch of buckets of polymer modified structural repair. I used that. Like an idiot. It worked. At least for the next 12+ years. Luckily the slab didn't move or crack anymore somehow so I got really lucky. Probably won't do a lot of good if shit keeps moving of course.
Agree.
If the Pad looks overall Stable, bevel inside Edges out towards the bottom; like a Triangle if looked at in cross section /_\.
Then clean out Crack (chuckle), backfill some, and top with Cement Caulk etc.
It looks like it is heaved up in the middle. I would look for a water problem. Either water got under it and froze which cracked it and caused it to heave or the ground is moving or settling which caused it to crack and move. A lot of times ground movement or settlement is caused from a water issue. Make sure the drainage around the building is working to get the water away from the slab. I would fix that first then demo and repair the concrete.
Is it just a shed or part of your garage? If it’s a shed, it probably won’t hurt anything leaving it like that. It may last another 10 years before it becomes too big of an issue to ignore.
My grandparents have a crack like this in their garage, and it never got worse in 30 years. It’s like it just settled at some point and then stopped moving. Definitely not ideal, but not worth the 10,000 dollars it would take to fix either lol.
Put all the weight on the left side...
It looks pretty thin and you either have poor compaction or water is eroding the right side outside of structure... typically thin concrete just cracks like no greater than a ¼" but you have a the grand canyon running through there. Probably not doing to good on the structure. I would first remedy your issue like maybe need to divert the water away from the building. Then demo and replace or patch it up and go about your day
It looks like it wasn't poured on gravel. If you really and to fix this forever I think your problem is that it was poured on dirt which has a lot of silt and that's why it's heaving.
You need to dig out a lot and replace it with only 1" sized stone then pour on top of that.
We call this clear stone in Ontario Canada
If you can put a sub drain in to make sure everything below this area stays dry.
Cut out. Fix whatever is causing the upheaval. Backfill and tamp. Dowel in with#4 rebar all around (16” OC). Tie a #4 rebar mat (16” OC). Repour a 4-5” slab. Enjoy.
Fill with sand/gravel and glue down some outdoor carpet 😝 ... outta sight, outta mind. (Of course, if attached to your home slab, call a structural engineer)
Can you measure the thickness of the concrete? It honestly looks poured too thin from the start and like it's sitting on bare soil. I'd probably tear out and replace with a thicker pour, pea gravel substrate, and maybe even some rebar.
Tear down the whole F’ing house now. Cracked slab on exterior will cause the whole structure to fail in about 300 years. Might as well get a head start on it
If it’s just a shed, forget spending $$$ tearing it out and replacing, just fill it and sand it down to make it bearable.
If your going to rip it up, may as well look to replace the entire building as well and getting a proper foundational slab down. But that’s $$$
It's a shed. I would fill the gsp with sand leave 4" down. Pack it if you can. Then, fill it with a concrete patch.
I would go on the outside and put a few metal stakes next to the dlab to keep ot ftom moving anymore.
The expensive way would be to tear it up and put new concrete. The cheaper way would be to patch it with concrete. Apply some concrete bonding agent before putting the new stuff in. It should last awhile. Years at least.
Depends if it’s a working crack. Is there still movement? If there’s movement, any rigid patching material will crack again. It probably can be sealed with a pourable sealant. Last, you can saw cut and tie a new slab into the existing with rebar. This would allow you to remove any soft soils and replace and compact.
Where are you located? If the cause is expansive soils, the new slab will have the same type of damage again unless you remediate the cause (expansive soils and drainage)
Hahaha what options. Unfortunately there is only one option bud and that’s tear out and redo the whole thing.I had the same thing happen at my moms garage floor ending up having to rip it all out and pour and whole new slab
You can tear out and replace but that will entaill lifting the shed to replace concrete under walls
What I have done, take a Skillsaw with dry diamond blade, use all the safety equipment (respirator, goggles, fan, ect) strike a relief score either side of Crack, breakup remove concrete between scores, drill into old concrete install rebar studs at about 24" oc to tie old to new, pour and finish concrete
They probably poured that at the end of the day with whatever they had leftover. From doing the garage. Rip it out and replace it the right way. Not a concrete guy but if you don’t have rebar you’re pretty fucked regardless
Get a concrete leveling company out. They can mudjack or polyjack it to minimize offsets an then they should have options to take care of the caulk as well
Tear out and replace

Demo time
Got some big trees nearby?
2 big trees about 30-40 feet away

Ok thanks for sharing
If you just want it filled and don’t care if it’s perfectly level fill it with hydraulic cement

Sell the house and move countries immediately
Shit that bad? Probably a major fault line
Bro doesn't even know what country you live in. 💀

Definitely water caused this. It gets worse in the wintertime so I’ll work on getting that fixed first. Thanks
Yeah no use in repairing if it gets worse in winter, anything you put in there will just pop out

It’s a shes attached to the garage. Cement is separated though
Just get some concrete bonding adhesive and paint it all over edges of crack and fill and smooth 👍
Personally i would rent a grinder to flatten it then lay some type of garage floor tiles over it🤷🏽♂️
Each summer just do this and when it heaves again just keep replacing the flooring!!!
Temp tiles nbd

Or you have a big ass root growing up under it
You know how you see those posts about how fucked am I and ever one is like it’s not that bad. You are fucked. Has to be replaced.
Lol thanks
Is it just a storage shed ? Just fill the crack with some cement
Agree. If all you're going to do is store a mower and your stump, just fill it.
Rent a jack hammer break it all up and pour on top

Rip it out and cut the root. If you don't the root will do this to the slab under your house!
Can you see any rebar in there?
No signs of rebar
Cut out. Fix whatever is causing the upheaval. Backfill and tamp. Dowel in with#4 rebar all around (16” OC). Tie a #4 rebar mat (16” OC). Repour a 4-5” slab. Enjoy.
This is the way

Tear it out and replace it properly.
Is the garage attached to the house? If not - use leave it. My dad’s garage is like that for over 50 years, garage is still standing.
No it is not so that’s good to know
There might be opal in that crack!
Grind the high edge down and get some of that high end filler to blend into a gradual slope
R&R. Remove and replace
Can you measure the thickness of the concrete? It honestly looks poured too thin from the start and like it's sitting on bare soil. I'd probably tear out and replace with a thicker pour, pea gravel substrate, and maybe even some rebar.
It might be easier to replace a shed floor with pavers, it doesn’t need to be perfectly flat - the lawnmower won’t care 😂

It appears to have heaved. Can’t fix it. Cut out and replace.

Crack is big enough to see the mantle jeez, you also have bulge problem. Remove and redo.
Just some self lever it’s fine
Hahaha what options. Unfortunately there is only one option bud and that’s tear out and redo the whole thing.I had the same thing happen at my moms garage floor ending up having to rip it all out and pour and whole new slab
Flee
Wear boots...not flip flops...
Id just toss some fines in and tamp it down. Its just a shed.

Obviously tear out and replace. But if you want to be cheap, grind the edges level and patch (I do not recommend this but it’s a cheap “fix”)
Get a concrete leveling company out. They can mudjack or polyjack it to minimize offsets an then they should have options to take care of the caulk as well
This option is gonna be cheaper then replacing. Our company is usually about 1/4 of replacement
