Abstract
A method is described for preventing and comabating corrosion on semi-dry, moist and wet concrete marine structures, comprising that, against the surface of the structure to be protected on a permanent basis, there is fastened an inert, conductive material, pressed by the fastening against an intermediate contact-establishing, hydroscopic material, and where a voltage is applied on a permanent basis between the reinforcement in the concrete and the affixed inert, conductive material.

A method for cathodic protection against reinforcement corrosion on semi-dry, damp and wet concrete marine structures, comprising that, against the surface of the structure to be protected, an inert, electrically conductive anode material is pressed against a layer of an intermediate, moisture-adsorbent and contact-establishing material, which optionally is impregnated, and that a voltage is impressed on a permanent basis on the reinforcement in the concrete and the affixed inert conductive anode material, wherein the structure and the moisture-absorbent contact-establishing material are maintained in a moist or wet state because of the nearby seawater.
