The use of coated titanium mesh, applied to a concrete structure and then overlain with a cementitious cover as part of an impressed current cathodic protection of rebar method, has been studied. Aspects considered have included the durability of the coating, the coating/cementitious interface and the cementitious cover itself. It is concluded, provided that appropriate type and loading of electrocatalyst are applied to the mesh, that real current density on the mesh is restricted, then the overall system is not only practical but should remain sound for periods measured in terms of tens of years.
