can brick ties be attached to existing CMU backup?
(OP)
Silly question...if you have an existing CMU block + brick veneer wall system, and a big portion of brick is damaged, can you simply strip off the brick and attach new brick ties to the existing CMU, then lay in new brick?
Or do you have to replace the CMU backup also so that you can embed your new brick ties in new CMU mortar joints?
thx

Would also have to make another hole just below each bond beam to insert the grout at each cell used. If K-web was used though, you would have to use more grout, but itshould still work.

Because veneer is vertically suported and the lateral loads are low, the necessary code requiments are minimal and are a measure of practicality.
Power actuated fasteners are satisfactory and hand installed (cut nails or tapcons) are probably overkill. It is not more critical than attaching vinyl siding to a wood frame structure - the same code requirements apply.
