The IICRC further separates water damage into four classifications:
Class 1: In which a nominal amount of water has flowed onto materials that are predominately low porosity. This class of normal water damage requires limited minimization and little moisture is left after the volume of water is removed, going out of minimal evaporation needed to finish drying. Examples would be a burst water tank on a closed concrete floor or an overflowed toilet on a tile floor.You can also click on the website to get more information about the water dmage restoration services in your area.
Class 2: Where there is a significant amount of drinking water discharged and the open materials are medium to high porosity. There is a greater absorption of water in to the materials and the water damage process is lengthened by the volume of water which needs to be removed and an extended drying time. Examples is a ruptured pressurized water collection inside a gypsum table wall, or a wood made floor joist system.
Class 3: Where a huge amount of water, regardless of its category, is soaked up by highly porous materials, resulting in the very best rate of evaporation essential to impact the water damage repair process. Examples are a storm-forced leak, which surges a building's interior and soaks carpeted areas, or broken water mains completing an underground parking area.
Class 4: Where normal water intrudes and is stuck by building materials and assemblies, which makes the restoration process difficult, labor intensive and expensive.
Affected areas are highly porous or tightly confined and require special methods and equipment, longer drying time or substantial vapor pressure differentials. Examples would be stormwater flooding of wooden, plast typer, masonry or concrete enclosures or a severe sewerage backup that permeates floor and wall systems.
When the categories and category of this particular damage have been assessed, proper steps can then be taken up mitigate and repair break down. Flood damage to a factory from black drinking water requires different processes than a potable water leak in an job site.
Every range of category, calculated and compounded by the class of water intrusion, will require different skills for evaluating the damage and selecting the right water damage restoration process and equipment.
