Water Damage Classifications
Level of water absorption into affected materials.
(+Select for info)
+ Class 1
- Class 1 – (least amount of water absorption, and evaporation): Water losses that affect only part of a room or area, or larger areas containing materials that have absorbed minimal moisture. Little or no wet carpet and/or cushion are present.
+ Class 2
- Class 2 – (large amount of water, absorption and evaporation): Water losses that affect at least an entire room or carpet and cushion (pad). Water has wicked up walls less than 24”. There is moisture remaining in structural materials (e.g., plywood, particleboard, structural wood, concrete).
+ Class 3
- Class 3 – (greatest amount of water, absorption and evaporation): Water wicked up over 24″, or water may have come from overhead affecting ceilings, walls, insulation, carpet, cushion and sub-floor. The entire area is saturated.
+ Class 4
- Class 4 – (Specialty Drying Situations): These consist of wet materials with very low permeance/porosity (hardwood, plaster, brick, concrete, stone). Typically, there are deep pockets of saturation, which requires very low specific humidity.
