I've been educating myself about split face block issue for a few weeks, and there is a lot of contradictory information out there. Is there a consensus yet on the best approach to dealing with moisture in single wydth split face block construction? There are a lot of masonry contractors, even large reputable ones, who will sell a $15-20k silane/siloxane sealant job to small building. However, I see lots of condo associations re-sealing after just 5 years. This is financially untenable for a 3 unit building. I've seen an alternate approach to venting at the top of the parapet walls, essentially using the hollow core of the single wydthe wall as an air gap. This approach makes a lot of sense to me, and *looks* like a more sustainable long-term solution. However, Wick Right seems to have a patent on this approach, and I'm dubious that they are pushing a proprietary solution for their own interests. What are you all recommending to your clients as a permanent and sustainable solution to the issue?
