Corrosion problems associated with late 19th Century and early 20th Century masonry-clad, steel-framed buildings have become increasingly evident during the past two decades. Corrosion induced damage not only destroys the structural integrity of these buildings, but also could pose a serious public hazard and liability issue for the owner. Corrosion control for masonry-clad, steel-framed buildings is gaining increasing importance. This is due to the mandate in today’s society to preserve aging historical structures, building safety issues, as well as the economic considerations for repair or replacement. Cathodic protection is an accepted technique for prevention of corrosion. The aim of this paper is to provide a case history of how cathodic protection was applied to preserve a historic masonry-clad, steel framed building in San Francisco, CA. The application of cathodic protection substantially reduced the cost of the building repair, facilitated completion of the repair on time, and more importantly, for the owner, the work was invisible to the untrained eye.
