Initial Situation

As a result of high repair costs for existing car parks, the city administration decided to install sensors for moisture and corrosion in the new building. The reason for this is the early detection of damage and the monitoring of the building up to the VOB (The German Construction Contract Procedures) acceptance and beyond.

Due to the special construction method (built-over roof of the underground car park), particular importance was attached to moisture monitoring, as the sealing of the roof surface is not accessible. Therefore, moisture sensors were to be installed in the low drainage point of the car park ceiling and in the drainage joints of the entrance ramps.


Installation of CorroDec®2G moisture and corrosion sensors (standard version) at the pillars of the parking deck and the most frequented parking slots.

Installation of humidity sensors (special design) in the drainage area of the four ceiling tiles (40m x 20m x 0.5m) – reading from the bottom of the concrete slabs.

The readout of the data was performed by the handheld reading device on site. With the new generation of sensor CorroDec®2G, this is now easily possible to do remotely or from a distance.

Added Value

  • Uncomplicated visualization of the building condition
  • Significant cost reduction in subsequent concrete repair due to early detection of damage
  • Sustainable safeguarding of investments
  • Proof of construction quality
  • Differentiated repair in case of OS system failure
  • Targeted control of the inspection intervals by querying the humidity values
  • Reduced blocking times for subsequent repairs
