14 IICRC CEC (Prerequisite: IICRC Certification in WRT) The IICRC-approved Applied Structural Drying (ASD) course is designed to teach the effective, efficient, and timely drying of water-damaged structures and contents, using comprehensive classroom and hands-on training, in order to facilitate appropriate decision making within a restorative drying environment. Learn proper extraction from Destry Ransdell, an industry expert, as we take our ASD facility and flood it with 2,000 gallons of water! That’s 16,680 pounds of water. Spend time learning how to monitor the drying process and provide critical documentation to support it.
