Corrosion damage is a multibillion dollar problem in the United States and other developed countries of the world with an estimated cost figure of 3-4% of the gross national product. Approximately a quarter of this cost can be attributed to corrosion of reinforced concrete structures such as bridges, parking garages and buildings. The first step towards adopting corrosion control measures and mitigating further damage in these structures is to carry out a corrosion condition survey.

The corrosion condition evaluation of reinforced concrete structures entails the judicious use of a number of techniques and methodologies such as visual inspection, potential mapping, corrosion rate measurements, cover thickness, chloride content analysis etc. to get a proper assessment of the situation so that appropriate corrective measures can be taken. The present paper discusses the various techniques and presents a case study related to a parking garage.
