Abstract
Corrosion of steel in a concrete structure such as a column in sea water occurs primarily above the water line and is inhibited using cathodic protection by attaching to the column an impervious sealed sleeve in which is provided a sacrificial anode in sheet form in contact with a layer of water transport medium so that water from the location of the bottom of the water transport medium within the water is carried into the area of the sacrificial anode to enhance ionic current.
