Boppard, Germany recently completed the construction of a parking garage in which RFID-based sensors were embedded in the building’s cement, in order to detect moisture and corrosion. The passive tags with sensor, which were placed below the cement’s surface and above reinforcement steel at select spots throughout the parking garage, can be read via a handheld device to detect the onset of corrosion or excessive moisture. This enables the city to repair the problem before it can harm the actual reinforcement steel. The so-called “CorroDec” corrosion-monitoring system was developed in cooperation with BS2 Sicherheitssysteme GmbH, in Boppard, which manufactures security and construction-monitoring solutions.
