Concrete cracks! **PICS***

[jakes29]

Greetings from Oklahoma. There was a small metal shed at my house when i purchased it 3 years ago. The slab has major cracks(see pics). The door no longer stays in the track, barely opens. Presumably due to the crack widening the frame.

What are my options here? Is there any way to repair or is a jackhammer in order???

Thanks for looking

There are several ideas in your other thread, but if you want it done right unbolt the shed from the slab & replace the slab with a good one done correctly.

I'd say you have three options;

1) Try to salvage the existing slab using the suggestions offered in you other thread. This might keep the problem from getting worse but it would look like hell.

2) Replace the entire slab as suggested by Jinks and others. Probably the only sure fire way to solve your problem but obviously expensive

3) Remove the loose piece of concrete, rebuild the base, drill and dowel into the remaining slab and place a new section of slab. Maybe a good compromise with a reasonable chance of success.

No magic bullet here but you have options. Good luck!

Sorry about the double post guys. And I appreciate the advice

Oh my. Well, that pretty much matches the mental picture I got from the other thread.

So, my approach would start with determining WHY the slab is separating at that crack. Is this simple frost heave? Is the underlayment shifting? If it is the former, perhaps a new slab would fix the issue (or maybe you could just fill the crack with hydraulic cement to keep water out). If the latter, is this on a hill that is sliding?

Doors and windows sticking are the usual first signs of a building failure, because they're the most sensitive to this sort of motion. I don't think you're in danger of imminent collapse, but if left unchecked...

I’ve got a small pond on the property and the terrain is sloped to fill the pond. My guess is, their wasn’t enough prep work to account for this being that it is roughly 20ft from the pond. But again I’m no expert. Now I’m left with the aftermath. Wonder if there would be any other door option if I remove the current roll up. It literally will raise up a foot then I have to crawl under it to get to the inside and keep it on the tracks to raise it.

For the time being, I would use Rust-oleum concrete patch and repair kit. I applied it to my control joints and cracks in my garage floor before epoxy and was impressed with the results.

Cheap and easy for now. its on amazon search "Rust-Oleum 301012 Wall-Surface-Repair-Products"
