Building materials are, for the most part, porous structures which generate permanent changes when in contact with moisture, which could be in the vapour phase and in the liquid phase, with the environment in which they are placed. This behaviour conditioned their properties and their durability. It should be noted that humidity is a major cause of the pathologies observed in buildings. The profile of the transient moisture content describes moisture content as a function of time and place. This profile is essential for determining the moisture diffusivity of a material and is also important for studying the interface phenomena. In this sub-chapter, a brief description of the most important experimental transient methods—Gravimetric Method, Nuclear Magnetic Resonance (NMR) method, X-Ray Analysis and Gamma Ray attenuation method—to determine moisture content profiles is going to be presented.
