Overhead door frame widened by splitting voncrete

[jakes29]

Have a small shed with a roll up door(rolls up into itself). The slab was done poorly, has cracked near the door opening and has widened the frame so much that the door no longer stays in the track. Has anyone experienced anything similar? Wonder if this could be a diy repair. In my inexperienced brain, all I see is a tear down since the frame will continue to widen as the concrete continues to split.

I would first worry about the shed collapsing. Shimming the door track should be simple enough.

Forgive my ignorance but there are ways to repair splitting concrete or no?

This concrete is moving horizontally? Is that what you are saying? Are you saying the location where the bottom of the door frame was is now in some other location because the floor moved?

If that is what you mean, then that is indeed quite unusual. Not easy to answer.

I have an outdoor slab that behaves this way. The slab was poured above grade on crushed stone. It has separated in 3 places. There's nearly an inch gap between the pieces. My assumption is that it's due to freeze/thaw cycles during the winter. The pieces of the slab are being slowly pushed apart.

About the best you can hope for is some way to stop it from expanding further. Maybe make some type of "dutchman" with rebar epoxied into both halves. (BTW: Avoiding this is the type of situation is why rebar is put in slabs.)

Vertical crack and broken concrete moving horizontally ?

Maybe you can tap con some pieces of angle iron to each side. Drill a few holes in opposing faces of the angle (prior to installing) and insert some all-thread. Nuts on both sides when tightened maybe draw the concrete back together.

Wow. Great responses guys. I did make another post in the flooring forum and have some pics on that one. These repairs are far beyond my level of expertise and it’s looking like I’ll be forking over some cash for repairs. In the mean time I’m left with a door that barely opens.

You should be able to adjust the door track to get it opening ok again, but the problem with your foundation needs to be addressed to permanently fix the issue and make sure you don't have further issues like the whole building collapsing.
