Weepless? Why?

  • 1.  Weepless? Why?

    I've noticed (in New Jersey) that developers back in the early 90's (and before then) put up many houses with brick veneer on the front face of their models and they all seem to lack weeps. I looked back at the 1992 CABO One and Two Family Dwelling Code and saw the only reference to weeps was in a diagram (Figure R503.4). Absolutely no other reference or description as to what the weep was. Did building officials at the time just ignore the diagram, was it something developers knew they could avoid? In 1996 the newly adopted CABO 1995 Edition put additional information as well as a description which has been unchanged to date. The IRC 2015 cites it almost the same word for word.
    So why was that and has anyone found these development homes to be failing some 25 years late? No legal issues just writing a blog.
    Thanks for anyone's insight.

    Brick veneer is a completely different animal than a brick masonry cavity wall. There really isn't anything to weep from in a brick veneer.

    [Edit]
    Ok, it took me awhile to find the applicable CABO diagram (page 46 here). I see that they're (and presumably you are) referring to a veneer brick as opposed to today's brick veneer (lick and stick) that you see everywhere these days.

    The diagram is correct. You should have weeps to drain the cavity between the veneer brick and the sheathing. Trying to get masons to install weeps even today can be an issue and it isn't always something that the inspectors are even going to notice.

    Thomas Bank II that is correct I am not speaking of an adhered veneer. I am referring to a brick veneer as per the following description:

    and the actual CABO code I'm referring to is this one;

    I have noticed in many residential applications that the tiny air space gets clogged with mortar. The air space should be more than 1" and mortar net or similar product used, or the weeps would just get clogged and be irrelevant.  Getting a residential mason to do this can be difficult even though it is standard practice for commercial work.
