Class 4 Water Loss
Specialty drying situations.
These consist of wet materials with a 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 to remove.
This class of water includes situations where moisture is trapped deep in dense materials like hardwood floors, sub-flooring, and plaster walls. This "bound water" is difficult to remove and will require the use of special drying tools and techniques. Additional drying time may be required to maintain a balanced environment so as not to cause damage to other materials in the loss through moisture removal
