IICRC Applied Structural Drying Practice Exam 2026 - Free Practice Questions and Study Guide for Certification

Class 2 water absorption refers to materials that have absorbed between 15% to 40% of their weight in water. This classification is important in the context of applied structural drying because it helps technicians determine the severity of the water intrusion and the appropriate drying methods and equipment to use.

Materials categorized under Class 2 typically involve damage that affects both the surface and some of the underlying core materials, which can lead to increased drying times and potential for mold growth if not addressed promptly. Understanding this classification assists restorers in developing a strategic drying plan tailored to the specific conditions of the affected environment. Class 2 represents a moderate level of water invasion that requires careful assessment and management to restore the structure effectively.
