Repairing Cracked Masonry

[Subject Prev][Subject Next][Thread Prev][Thread Next]

For the sake of brevity I will condense a very complex problem into a simple question that I have no answer for: I have a large crack (actually many large cracks) in the brick veneer on an eight story building. This crack allows water to penetrate the building and attempts to caulk have been unsuccessful as the crack moves thereby dislodging the caulk. I am contemplating the addition of a small (say #2) rebar in the grout joint (grind out joint repoint with epoxy mortar or other?) so that the reinforcing crosses the crack in essence stitching the crack together. Then applying the caulk with the idea that the added reinforcing will control the crack from movement beyond that which the caulk can tolerate. I can see extending the reinforcing 24" or 36" on each side of the crack This is not to stop the building movement but to facilitate waterproofing the brick facing.

My simple question is--- will the rebar bond well enough to the brick and mortar for this to be effective? Any thoughts will be greatly appreciated ~:-).
