Techniques based on electroosmosis have been proposed as restoration methods to reduce the moisture content in masonry subjected to capillary suction. Although several applications have been reported in the literature and beneficial effects of electroosmosis are often claimed, very little technical information is available. Quite rarely quantitative measurements of humidity changes in the masonry following the application of the current are reported. This paper reports the results of a research work aimed at studying the electroosmotic transport through porous construction materials, in order to investigate the factors that influence electroosmosis and define its actual technological applicability for the rehabilitation of damp masonry. The experimental tests showed that, for several concomitant circumstances, the chances that the technique based on electroosmosis might be effective in drying damp masonry are extremely low.
