Categories of water damage :
Category 1 – refers to clean water floods that don’t pose any threat to humans. This can be clean water from a tap.
Category 2 – also known as gray water floods. The water in this flood is grey in color, contaminated, may contain microorganisms, and will cause sickness if ingested. The source of this water may be broken sump pumps or broken toilets.
Category 3 – also known as black water. This type of floodwater is sourced from an extremely unsanitary source. It could contain animal or human waste. This type of water contains bacteria and other pathogens can make humans severely ill once ingested.
A house flooded with black water can still be restored, however, it will be a costly undertaking. As you will likely have throw away all the furniture and household item that came into contact with the water, and you may have to replace much of the structural components like the floors and walls.
Classes of water damage.
These classes are vital in determining the damage levels. they are:
Class 1 – under 5% water absorption. This is the least harmful and easy to remedy as the materials have absorbed very little water.
Class 2 – widespread flooding with a fast rate of evaporation. Meaning in this class the water has damaged the carpet and floor tiles. Repair is more difficult compared to class 1.
Class 3 - this class has the highest rate of evaporation. Damage may include soaked furniture and walls. The sources of water are mainly overhead sources like broken sprinklers.
