Moisture Control Strategies

Understanding the patterns of moisture accumulation in buildings provides the basis for preventing moisture-related problems when commissioning a building or when analyzing the relationship between HVAC systems in the building envelope. Although mold and moisture growth staining and corrosion are the most visible signs of moisture-related damage and buildings, they are only symptoms of the fundamental problem of uncontrolled moisture flows. Thus, controlling the flow of moisture is key to preventing premature degradation of building components.

Moisture related building damage can result from any of the following events:

Intrusion of bulk moisture (i.e. rainwater and groundwater)
Moisture generated internally by human or operational activity
Moisture […]

Stucco Myth #3: Direct-applied stucco is easily packed out to meet a finished plane.

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.)

Myths abound around stucco cracking. In truth, it is not abnormal to have some cracking with stucco, much of which can be relatively harmless. The key is paying attention to the types of cracks, and minimizing any significant issues that might lead to actual failure, including debonding, water intrusion, and mold problems. It is not a good idea to […]
