A method for cathodic protection comprising: providing steel material; applying a covering material such that a part of the steel material is at least partly covered by the covering material; forming a cathodic protection combination by: providing an anode member comprising an anode body at least partly formed of a sacrificial anode material; arranging the anode member at least partly in contact with the covering material for communication of ions therebetween; and electrically connecting the at least one anode member and the steel material so that an electrical potential is generated by galvanic action between the sacrificial anode material and the steel material which causes ions to flow through the covering material tending to inhibit corrosion of the steel material while causing corrosion of the anode member; wherein the corrosion of the sacrificial anode material acts to form corrosion products where the corrosion products have a greater volume than that part of the anode member from which the corrosion products were formed thus tending to cause expansion of the anode member, the contact between the anode member and the covering material being such that the expansion tends to breakdown the covering material or the connection between the covering material and the anode member; and resisting the expansion of the anode body and thus restricting the expansion and the breakdown caused thereby by providing a reinforcing layer at or adjacent the anode member which applies restraining forces to the anode body. providing steel material; applying a covering material such that a part of the steel material is at least partly covered by the covering material; forming a cathodic protection combination by: providing an anode member comprising an anode body at least partly formed of a sacrificial anode material; arranging the anode member at least partly in contact with the covering material for communication of ions therebetween; and electrically connecting the at least one anode member and the steel material so that an electrical potential is generated by galvanic action between the sacrificial anode material and the steel material which causes ions to flow through the covering material tending to inhibit corrosion of the steel material while causing corrosion of the anode member; wherein the corrosion of the sacrificial anode material acts to form corrosion products where the corrosion products have a greater volume than that part of the anode member from which the corrosion products were formed thus tending to cause expansion of the anode member, the contact between the anode member and the covering material being such that the expansion tends to breakdown the covering material or the connection between the covering material and the anode member; and resisting the expansion of the anode body and thus restricting the expansion and the breakdown caused thereby by providing a reinforcing layer at or adjacent the anode member which applies restraining forces to the anode body. providing an anode member comprising an anode body at least partly formed of a sacrificial anode material; arranging the anode member at least partly in contact with the covering material for communication of ions therebetween; and electrically connecting the at least one anode member and the steel material so that an electrical potential is generated by galvanic action between the sacrificial anode material and the steel material which causes ions to flow through the covering material tending to inhibit corrosion of the steel material while causing corrosion of the anode member; wherein the corrosion of the sacrificial anode material acts to form corrosion products where the corrosion products have a greater volume than that part of the anode member from which the corrosion products were formed thus tending to cause expansion of the anode member, the contact between the anode member and the covering material being such that the expansion tends to breakdown the covering material or the connection between the covering material and the anode member; and resisting the expansion of the anode body and thus restricting the expansion and the breakdown caused thereby by providing a reinforcing layer at or adjacent the anode member which applies restraining forces to the anode body.
