The cracking, displacement and spalling of stone and masonry due to the corrosion of steelwork is becoming increasingly common in masonry clad steel-framed buildings constructed between the late 1800s and first half of the 20th Century. This is a serious condition that results in significant deterioration and loss of the original facade and necessitates both costly and disruptive methods of treatment. In recent years the problems of corrosion related deterioration of the steel frame and associated fixing details not only lead to costly cycles of repair but also to serious injury and even death due to masonry spalls.

This presentation provides an overview of cathodic protection repair techniques developed in the UK over the past decade to combat the problems of corrosion deterioration.
