Moisture within roof assemblies, or the concern over such, has recently become a major focus of discussion for the design/build community due to project schedule delays and disruptions to businesses and institutions. Despite the disruption to projects this issue causes, there remains significant misunderstandings across the design build industry regarding product warranties, field moisture tests, and just how long it takes concrete “to dry”. During this presentation, we will discuss common terms associated with concrete that are often misused and misunderstood. Further, the various sources of roof system moisture will be identified with clear recommendations given as to how the specifying professional can proactively address these sources through the construction documents.
Dean E. Craft , LtCol USMCR (ret), ASTM, CSI, CDT is the President & COO of ISE Logik Industries, the manufacturer of MVRA 900 moisture vapor reduction admixture; and, since 2009, has presented more than 1000 times on how to proactively address concrete moisture in the design phase. Dean is the principal author and technical chair of ASTM F3191 – 16: “Standard Practice for Field Determination of Substrate Water Absorption (Porosity) for Substrates to Receive Resilient Flooring”, completed his doctoral work in 2017 with a dissertation entitled “Fallacy of Current Industry Approach to Assessing Concrete Moisture Before Flooring Installation”, and is a voting or participating member of:
- ASTM Committee D08 on Roofing and Waterproofing
- ASTM Committee F06 on Resilient Floor Coverings
Dr. Craft is a retired, U.S. Marine Corps Lieutenant Colonel with 23-years of total service; and is an expert in assessing organizational behavior and implementing organizational change through leadership and process improvement. He is a graduate of the United States Naval Academy (BS), the Naval Postgraduate School (MS), and California Intercontinental University (DBA; Doctorate in Global Leadership).
Learning Objectives:
- Examine the role of moisture in concrete and address misunderstandings across “hydration”, “drying” and “curing”.
- Discuss the meaning of “28 days” in relation to freshly placed concrete.
- Identify the various sources of roof system moisture.
- Specify appropriate sustainable design processes, procedures, and site conditions to minimize roof system installation delays and subsequent bond or moisture failures.
