Four Primary Classifications Of Water Damage
Class 1: The least amount of water, absorption and evaporation. It affects only part of a room or area, or larger area containing materials that has absorbed minimal moisture. Little or no wet carpet and/or cushion are present.
Class 2: Involves a large amount of water, absorption and evaporation. It affects at least an Entire Room of carpet and cushion (pad). Water has wicked up walls less than 24 inches. There is moisture remaining in structural materials and substructure soil.
Class 3: Involves the greatest amount of water, absorption and evaporation. Water may have come from overhead: Ceilings, walls, insulation carpet, cushion and subfloor in virtually the entire areas are saturated.
Class 4: Relates to specialty drying situations. Wet Materials with very low permeance / porosity (e.g., hardwood, plaster, brick, concrete, light Weight concrete and stone). Typically, there are deep pockets of saturation, which require very low specific humidity. These types Losses may require longer drying times and special methods.
