spalled brick directly above steel relieving angle
spalled brick directly above steel relieving angle
(OP)
I have a 40 year old concrete framed building with brick face and six inch block backup. Brick over windows is supported by concrete lintels that extend from the spandrel beams. The adjacent brick beyond the windows sits on steel relieving angles bolted to spandrels at the same elevation as the concrete lintels. The brick directly over the relieving angles is spalled. What is causing this and can it be repaired?

I don't know of ways to repair spalling brick once they're in place. You may be able to paint them to prevent further spalling by minimizing moisture soakage.

how bad is the spalling? Is your concern structural or cosmetic?
RE: spalled brick directly above steel relieving angle
It is also possible the reason for the spalling is rust on the steel angles. Rust basicly expands the steel, and the pressure behind or below the brick can cause spalling. A common solution would be to remove the brick, clean and coat the angle with rust preventive coating, replace the spalled brick, and apply water repellant.

It could also be that someone caulked along the line of the weep holes. Everytime, I think that I have seen it all, I will discover another amazement.
