Migrating Corrosion Inhibitors or MCIs are surface applied mixed corrosion inhibitors, designed for use as an impregnation of steel reinforced concrete. These form a protective monomolecular layer on the surface of the reinforcing steel. Sacrificial Anodes are used in concrete rehabilitation to prevent the formation of new corrosion sites on adjacent rebar. 

The anode is fixed to the reinforcing steel by means of tie wires, which allow attachment in horizontal, vertical and overhead locations. Once installed, the zinc core corrodes preferentially to the surrounding rebar, providing ‘Cathodic Prevention’ and therefore preventing ‘Incipient anode’ formation. Pellet Vapour Phase Inhibitors vaporise and permeate the concrete substrate. The alkalinity ensures the pacification of corrosion as it is adsorbed to the reinforcing steel surface, blocking the path of Chlorides, Water and Oxygen, the fuel of reinforcement corrosion.
