AbstractEfflorescence is a problem of interest in building science for two reasons; it frequently causes severe disfiguration of buildings, and it may be the cause of decay of masonry materials. Efflorescence results from the movement of a solution of salts to the masonry surface where evaporation of the water takes place and the salts are desposited. The occurrence of efflorescence is influenced by the degree of dampness of masonry and the conditions of drying, both of which are controlled in large measure by weather factors. Decay is caused by crystallization of salts within the masonry material. The design and construction of a building to avoid excessive wetting of the masonry and the selection of materials free of soluble salts provide a solution to the efflorescence problem.
