ABSTRACT:
A method of installing a coated valve metal electrode as impressed-current anode in a cathodic protection system for a steel-reinforced concrete structure comprises providing a roll of coated valve metal mesh, unrolling the mesh and installing it in conformity with the structure, fixing the mesh to the structure and embedding the mesh in an ion-conductive overlay. The mesh is a highly expanded valve metal sheet providing multiple current paths and therefore enhanced redundancy. Current distributor strips can be welded to the mesh after unrolling.
