Straightening A Block Wall


I've got a 20' tall block wall on a commercial building that is buckling outward. What's the best way to straighten this thing? If I leave it as it is, fill cores every three feet or so will it be okay? thanks

Are you serious? Tear the f-ing thing down before some one gets killed.

Oh, come on, it's only buckling out not more than an inch. Surely there's a solution other than replacing it. That would be seriously major.

First you need to figure out WHY it is buckling, then you need to solve that problem, THEN you need to worry about repair/stabilization.

Re: Straightening A Block Wall


Is the wall loadbearing or is it just infill between columns and under beams?

A deflection or bowing adds to the bending moment and causes more movement. Since it has bowed that much, it has technically "failed" and is not as strong as when it was built. It will take some forece to bring it back to closer than original construction. Grout by itself does not help much, especially compared to rebar and grout.

It could also be from some humanly applied loads, like mistakes, unanticipated hanging loads or even bumping. In commercial building many strange things happen.

As TS said, there is certainly a cause and you have to determine that to come up with a repair and then corrective action.

I can easily get rebar in from the top. it is load bearing.

Re: Straightening A Block Wall


Get it plumb and straight before you build a reinforced wall or you just create a more permanent curved wall with lower strength.

Do you have any idea of the cause of the bowing? If not hire an engineer., since it holding up a lot of weight and resisting a lot of wind/suction.

Re: Straightening A Block Wall


When I do figure out the cause of it bowing, what should I do to straighten it?

Hey, I didn't think most contractors liked working with engineers!

Re: Straightening A Block Wall


That would be architects.

You don't seem to be taking the advice so I will say it again.

You need an engineer to look at this. Structural design is not your field of work. Get someone qualified who knows what they are doing with structural engineering to come look at it and design the proper fix.
