Learning Objectives:

  1. Examine the role of moisture in concrete and address misunderstandings across “hydration”, “drying” and “curing”.
  2. Discuss the meaning of “28 days” in relation to freshly placed concrete.
  3. Identify the various sources of roof system moisture.
  4. Specify appropriate sustainable design processes, procedures, and site conditions to minimize roof system installation delays and subsequent bond or moisture failures.

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.
