Flashing takes discipline, as the most anyone will see is the bent edge of a drip edge or a weep vent, but doing it correctly usually determines whether or not the job is profitable for everyone involved. As with all things, flashing masonry has a few standard rules.

The 2015 edition of the National Building Code of Canada (NBC) introduced 360 technical revisions that address contemporary concerns and raise standards even as Canada is in the midst of a construction boom.

The Adhesive and Sealant Council (ASC) created a first-draft Product Category Rule (PCR) for sealants in North America, which is open for public comment. PCRs set rules the industry should follow when conducting life cycle assessments (LCAs), which is then used to create an environmental product declaration (EPD).

The restoration of the Lieutenant F. Campbell, VC, Barracks in Meaford, Ont., required brick façade replacement to its military residence. The owner, Canadian Department of National Defense (DND), identified masonry deterioration due to the spalling of brick at the base of foundations and at lintels over most windows. The primary reason for this situation was the through wall flashings had failed to provide effective drainage from the cavity.

An important part of many Canadian project teams, the masonry industry is a proud group that builds durable structures using time-honoured techniques that have spanned generations. Discipline and mentoring are the keys to learning the ‘laws’ that make up this complex trade.
