This paper describes two very different projects where remote monitored corrosion monitoring systems were installed. It gives the results of monitoring a range of parameters from probes that were cast into new structures and those retrofitted into existing structures. The seasonal fluctuations of corrosion rates and steel/concrete potentials are illustrated and discussed, as well as trends with time as the newly constructed concrete settles down in one case but show more erratic behaviour in the other case where chlorides were cast into the concrete.
