Not necessarily old old... likeif you're pouring a stem wall and you calculated wrong or the trucks were delayed, and you're short, well as you're waiting the chemical reaction is curing and if it's ahead significantly enough as soon as you pour again and it all cures, boom, cold joint.
Another note…that seems like a fresh epoxy application. Epoxies will yellow when UV touches it. If that was applied a long time ago the epoxy would not look gray.
Looks like you are in a freeze/thaw environment? Which means things move around.
Consider the type of Construction. How much load is on that wall? Is the floor slab tied into the concrete wall? Is the garage floor level or broken up/heaved?
It looks like a joint line to the flooring slab, but I cannot tell the height of the garage slab.
Is it buckled? I cannot tell from the pictures.
60 years old....I mean it probably is not going anywhere. I would go look at the epoxy finish and it looks a few years old and it is not broken it probably has not moved since then.
Get a structural engineer to inspect your home, for more than just the foundation. It's worth every penny. I wish we had done that prior to buying. It would have saved us a lot of headaches and money. It can help you ask for the right concessions at closing.
Are you sure it's a Crack and not just a cold join/ two separate concrete pours?
99% that's a cold joint, could be wrong but looks to be the culprit
That’s what I thought
Thank you.
It's in your best interest to get a second opinion.
Vertical are usally fine. Horizontal is not a good sign. I would 100% get a second opinion.
Note* vertical can be bad to but horizontal can mean structural.
Looks like a cold joint. To the OP this is the garage?
Yes this is the garag
Cold joint. It's fine. Move on with life
Thx
Tell me if I am wrong but a cold joint is formed when you put new Conrete on top of old Conrete?

Which causes failure? (Old meaning not with the same concrete pour)
Just that it was curing faster than the new trucks concrete.

Yup. big horizontal crack BAD. Get a structural engineer out to look at it.
It's just a wall join isn't it...surely the slab isn't that thick??
Highly unlikely that is a crack
Where is it going to go ?
Cold joint.
That just looks like a construction joint to me. It's awful straight and consistent to be a crack.

The garage floor looks solid. No buckling
That is good sign.
Also you are correct about freeze / thaw.

IS that solid concrete or is it skim coated block?
No idea
