Abstract

A method of electrochemical treatment of building material (1) includes mounting on the material (1) an anode network (5) and spraying electrolytic material (11) onto the material (1) and the network (5) and leading wetting liquid via porous, distributing hoses (6) to a gap between the material (1) and the network (5). The method may include heating in the region of the electrode (5) in order to improve the efficiency of the electrochemical treatment, the power for the heating being supplied from a source (12) separate from the power source (7) for producing the electrochemical treatment.
