An electrolytic restoration of concrete includes an anode positioned at a surface of the concrete to be restored and the communication of a current from the anode to the reinforcing bars in the concrete as a cathode. The anode is in the presence of or carries an electrolyte so that sufficient current is provided temporarily over a sufficient period of time so that ions from the concrete are carried through the concrete and expelled into the electrolyte for extraction. The anode is provided by layer of conductive material which is particulate or fibrous so that it is a n amorphous layer which can therefore follow the surface of the concrete. In a horizonta l arrangement, the layer can be applied directly onto a felt mat for carrying electrolyte. In a vertical orientation an initial layer of chopped cellulose is wetted an d applied onto the vertical surface followed by the same layer carrying carbon powder so that the layer is conductive and forms the anode when connected to metal connecto r plates buried in the anode layer.
