The concrete cover can be evaluated by testing carbonation depth, chloride content, surface cohesion, resistivity and permeability. The reinforcement condition is evaluated by measuring cover depth, rebar thickness, and using the half-cell potential method.

concrete concepts uses the Canin+ Corrosion Analyzing Instrument to collect potential field data on active corrosion in buildings such as multi-story car parks where damage occurs due to de-icing salts dripping from cars. This data is used together with concrete cover measurements using Profometer and chloride distribution measurements. Analysis of the data allows corrective maintenance to be localized.

Without the comprehensive potential field and concrete cover measurements, the building contractor would be obliged to replace all of the concrete in order to ensure the durability of the concrete structures. In practical examples in such car parks, the concrete replacement programme was reduced by up to 85%.
