Abstract
The frequency of moisture-related claims in concrete roof decks has been increasing rapidly over the past few years. The issues are typically encountered on roofs that have not exhibited any leakage and generally appear to have been properly installed, yet when cut open, are found to be damp to wet across the entire roof surface. reasons for these issues include changes in system buildups, year-round construction in all climates, and accelerated construction schedules. Exacerbating the problem is the increased usage of lightweight structural concrete. This presentation will review the key issues involved and provide practical recommendations for preventing problems, as well as potential remedial approaches in situations where problems have occurred.
