Desalination of masonry by poulticing from laboratory to practice
conference paper
Salt crystallization is one of the most common causes of decay of porous building materials. Salts can cause damage when they, due to the presence of moisture, undergo crystallization/dissolution cycles. Removing the moisture source can
therefore stop salt decay. Unfortunately, this is not always possible (e.g. in the case of masonry exposed to rain) or not wanted (e.g. the invasiveness of airconditioning systems in monumental buildings). In these situations, desalination,
i.e. the extraction of soluble salts from the material, can offer a solution [a.o. 1‐2].
