CMU Wall Repair
CMU Wall Repair
(OP)
I have a situation where a residential house was built with CMU exterior walls and due to some settlement has a few 1/4" to 3/8" wide cracks as shown in the attached photo. This is a 50 year old building and has wood lintels and masonry lintels. The owner wants it repaired. I can take care of stabilizing the foundation but wanted to know what is commonly being practiced out there for the repair and sealing the cracks. Any help or reference material will be greatly appreciated.

If structural cracks are contiguous with an unfilled cell, pump or gravity feed polymer concrete in "soupy" consistency to fill void and provide crack repair.

Are there any good reference materials for these types of situation?

It may not be that clear from the photo but the corner crack is close to 1/2" wide and due to settlement.

The crack on the left under the window is probably shrinkage or temperature related as well.
There is no clear evidence of foundation settlement in the photo provided.

Now if there is no indication of settlement or foundation failure then I would address the roof framing. Are there ceiling joists or is the roof cathedral ceiling? the cracks could be induced by the lateral thrust at the wall plate in case of a vaulted ceiling.
