Introduction
The three most important questions considering salt or moisture damage are:
- Where does the moisture in the wall come from? Localization of moisture source
- How much moisture does the wall contain? Condition of moisture penetration Durchfeuchtungszustand
- How much salt is present in the wall? Degree of salinization
It is the objective of the moisture measurement is to detect the humidity that can actually be removed from a building material, i.e. not the chemically bound water or the semi free water. The chemically bound water (e.g. in gypsum  CaSO4 * 2H2O) should not be detected because it is a component of the building material.
