Unfortunately, numerous unfortunate conditions have occurred because of incorrect uses of materials and devices, or detailing errors. This article examines what design professionals need to know about allowing moisture to escape their masonry.

In other cases, the sash cord was fastened vertically up the backside of the cavity. In yet other instances, it would be pulled out of the wall, leaving a hole through the head joint or bed joint of mortar.

Continuing the Debate on Solar-driven Moisture

Our January 2013 article, “Ensuring Moisture Protection for Manufactured Stone,” written by Jeff Diqui, Arch. Eng., CSI, resulted in a letter to the editor from another frequent contributor to The Construction Specifier.

In the spring, Maria Spinu, PhD, LEED AP, e-mailed her comments:

I want to compliment Mr. Diqui on a generally well-written and informative article, but I wish to address the statements made … Continue reading Continuing the Debate on Solar-driven Moisture

Resulting problems related to moisture intrusion into the wall assembly’s dry zone are moist wall interiors, wet insulation, and rot in sheathing and framing.
