Classes of Water Loss
Water damage is categorized into four classes, all varying in severity. If your home has recently suffered water damage or a water related disaster, determining the classes of water loss is an important step in beginning water damage restoration. The more water damage there is, the higher the class. When looking for water damage restoration services, you can use this list to identify which class of water damage you are experiencing on your property. Identifying the classes of water loss enables restoration professionals to formulate a plan based on your home’s specific needs.
The Four Classes of Water Loss
Classes of water loss refer to the amount of water and the anticipated rate of evaporation based on the amount and type of wet materials in your home. There are four classes of water loss:
Class 1: Slow Rate of Evaporation
Class 1 water damage is the least severe, and easiest to deal with since it has a slow absorption rate. A class one water loss affects only part of a room with low-permeance or low-porosity materials such as particle board, plywood, structural wood, vinyl composition tile, and concrete. Water damage restoration services will be needed, but only light repairs will likely be necessary.
Class 2: Fast Rate of Evaporation
Class 2 water damage wreaks a little more havoc than class one. Class two water losses affect the whole room and materials such as carpet and cushion. Seepage of water up walls is less than 24 inches, and there is moisture in structural materials—this leaves the opportunity for lasting damage to the structure of the building.
Class 3: Fastest Rate of Evaporation
Class 3 water damage has the fastest absorption rate. Class three water losses typically come from overhead, saturating insulation, ceilings, walls, carpet, cushion, and subfloor in virtually the entire area, and/or it has wicked up the walls over 24 inches.
Class 4: Specialty Drying Situations
Specialty drying situations involve wet materials with very low permeance or low porosity. Examples include hardwood, plaster, brick, concrete, stone, subfloors and crawlspaces. Getting rid of moisture in these materials can prove to be difficult. They may need to be treated with low levels of humidity, and often take longer drying times and more specialized methods to be remedied.
In all cases, water in your home or property needs to be dealt with quickly but also professionally before your small issue turns into a large problem.
