Half-Cell Corrosion Potential Mapping

The concrete roof was a waffle slab system, with relatively small concrete cover. Sign of corrosion and delamination was observed in several areas on the lower section of the beams, and the bottom of the slab. The concrete slab was in poor condition on or around the construction joint area. Half-Cell Corrosion Potential Mapping and Hammer Sounding was used to assess the corrosion activity in the roof. Corrosion Potential Maps were developed to assist client with repair and maintenance.
