Moisture presence in concrete slabs can cause problems for all types of floors, including carpeting, wood, stone, poured polymeric, and resilient finish. Too much moisture can cause floorcoverings to cup, buckle, blister, and discolor, and these problems can occur days, months, or years after installation. In other words, excess moisture adversely affects the assembly’s short- and long-term viability.
Construction is underway on the Hilton Garden Inn, a 12-story high-rise on the University of Iowa campus. The team working on this 5110-m2 (55,000-sf) steel-framed hotel—including Cities Edge Architects and contractor Rushton Sheet Metal—has found a strong solution to the project’s variety of insulation-related challenges.
During a visit to review curtain wall assemblies on a project under construction, we noticed something unrelated—brick ties supporting a cantilevered through-wall flashing drip plate at a window opening in the exterior masonry. This unusual condition invited further examination of the cavity wall construction.
Designers are creating new and exciting contemporary masonry designs that demand clean, smooth wall plane elevations. One challenge that can interfere with unobstructed aesthetics is the visual effects of masonry drip-edge flashing. This potential obstacle has also carried through to traditional masonry design. Designers and specifiers can find it difficult to balance design and functional water management requirements.
