The National Wood Flooring Association has released the first installment of a two-part study on moisture issues, through its Industry Research Foundation. Part I, "Concrete Slabs and Moisture Issues," addresses three key components, including concrete and cement chemistry, concrete and cement technology, and approaches to remedy problem slabs with high moisture content. The report further addresses moisture sources, both natural and artificial, and testing methods, including qualitative tests providing a general indication of moisture and quantitative tests providing the level of moisture present.
