RE: Repairing Cracked Masonry

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

I suspect that your proposed solution will simply cause new cracks
elsewhere.  What about caulking all of the cracks with GE silicone, or
equivalent?  That might not be very pretty, but it ought to keep the
water out.

Subject: Repairing Cracked Masonry


For the sake of brevity I will condense a very complex problem into a
question that I have no answer for:
I have a large crack (actually many large cracks) in the brick veneer on
eight story building. This crack allows water to penetrate the building
attempts to caulk have been unsuccessful as the crack moves thereby 
dislodging the caulk. I am contemplating the addition of a small  (say
rebar in the grout joint  (grind out joint repoint with epoxy mortar or 
other?) so that the reinforcing crosses the crack in essence stitching
crack together. Then applying the caulk with the idea that the added 
reinforcing will control the crack from movement beyond that which the
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
mortar for this to be effective? Any thoughts will be greatly
