The measurements made with the Cor Map apparatus, using the half cell method, can be plotted on a grid and lines of equipotential contours drawn, highlighting areas of possible corrosion activity. Corrosion, which is an electrochemical process, occurs in concrete when oxygen and moisture are present.
