Water is a universal solvent which influences building defects/dampness due to salt movement.
Different materials in a building can absorb water at high humidity and release it at times of low humidity. The amount of hygroscopic moisture which a material can hold is variable, but salts increase moisture retention. It is why building professionals discuss the ability of a buildings ability to buffer moisture.
