What characterizes Class 3 water intrusion in structural drying?

In the context of structural drying, Class 3 water intrusion is characterized by significant involvement of water in the structural elements. This classification indicates that the affected area experiences a substantial presence of water, typically representing over 40% of the area. In Class 3 scenarios, water damage often reaches wall cavities, ceilings, and even insulation, making it distinct from other classifications where water may not have penetrated as deeply or affected as much area.

The defining characteristic of Class 3 is its impact on various materials and their ability to retain moisture, which in turn influences the drying strategy. When over 40% of the area is affected, it highlights the necessity for more intensive drying efforts, as the structure will have absorbed a considerable amount of moisture that must be addressed to restore the environment to a safe and dry state.

This classification emphasizes the importance of understanding the extent of water involvement in terms of area and material absorption to effectively develop a drying plan that will facilitate efficient removal of moisture and prevent further damage.
