The Four Primary Water Damage Classifications
The IICRC’s S-500 Standard and Reference Guide for Professional Water Damage Restoration separates water damage into four distinct classes. Each class is based on the severity of the water damage, and they determine what steps must be followed in the mitigation and restoration process.
Class 1 Water Damage - the least amount of water, absorption, and evaporation. These are water losses that impact only a small part of a room or area of a facility, or large areas that contain materials that have absorbed a small amount of moisture. Little to no carpeted or absorbent material present.
Class 2 Water Damage – significant amount of water, absorption, and evaporation. These are water losses that impact full rooms or carpeted areas. Walls are wicked less than 24 inches, and moisture remains in structural materials (Concrete, plywood, and particleboard).
Class 3 Water Damage – the largest amount of water, absorption, and evaporation. These are water losses that saturate an entire area. Walls are wicked over 24 inches or water may have entered from overhead, impacting ceilings, insulation, or sub-floor.
Class 4 Water Damage – Specific drying situations. Wet materials with low porosity or permeance such as plaster, brick, and stone. These materials can absorb water into deep pockets and can require extended drying times or specialized procedures and equipment.
