Installation limitations

The importance of selecting an appropriate weather-resistive barrier (WRB), given project-specific conditions such as substrate types and anticipated in-service environmental conditions, has been emphasized in several past Failures articles by these authors.

Stucco myths and facts

In our work as forensic architects and engineers, we are regularly involved in litigation over stucco failures, including hotels and high-rise condo complexes. (For this article, ‘stucco’ refers to traditional portland cement plaster direct-applied to a masonry substrate, rather than using lath.)

Open with care

Even within buildings experiencing recurring moisture-related issues, visible surfaces of interior finishes do not always provide an accurate indication of the underlying conditions within the exterior wall assembly.

Expansive grout as anchor fill

In stone veneer construction, the panels’ lateral support is typically provided by anchors connecting the stone veneer to a backup structure. Some lateral support anchors project from their attachment at the building structure, and are engaged within a slot or kerf cut into the stone thickness.

Expanding focus on movement

Many building components (including the structure itself) are required to accommodate in-service dimensional changes associated with thermal and moisture variations, as well as reversible and irreversible movements created by other types of structural and environmental loadings.

Complex corrosion

Galvanizing is one of the best ways to protect steel, but the complex series of reactions necessary to prevent corrosion can be undermined by exposure. When hot-dipped galvanized steel is first exposed to the atmosphere, near-pure zinc at the surface reacts with oxygen to form zinc oxide.
