The potential mapping method is the most suitable inspection method to detect ongoing
corrosion in reinforced concrete structures. The accuracy of this measurement method is expressed by
the Probability of Detection. In combination with potential mapping data gained from inspection the
information about the Probability of Detection delivers the needed information to update the service
life prediction of reinforced concrete structures. Potential mapping data includes information about the
temporal development and the spatial variability of corrosion. In this way, the condition of existing
structures can be evaluated more realistic. This paper presents a case study for updating the service life
prediction with concrete cover data and potential mapping.
