Or does the roof joist have to be shored and the entire wall rebuilt.
It s a best practice to use this same reinforcing steel to connect the concrete block walls to the poured concrete footer.
Window and door headers also known as lintels can be subjected to significant bending moment and shear forces depending on several factors.
After the wall is sized each wall member is checked for adequate strength and steel reinforcing is determined.
I then dropped the long steel bars from above down to the top of the footer so the steel pieces overlapped.
On the fourth course trowel a skim very thin coat of mortar on the block.
Also take a look at the ends of the steel bars disappearing into the walls and see if the rust runs in as well.

One of the most common and telling failures of retaining walls is the inevitable tilting cracking and bowing of brick timber and concrete block retaining walls built by homeowners well meaning builders and landscapers.
The presence of reinforcing steel dramatically increases the overall strength characteristics of masonry or concrete.
Reinforcement for wall openings.
Once the steel bars are exposed brush away every concrete attached to them using a wire brush.
