CorroDec - Corrosion / Humidity sensor

The structural infrastructure must always meet requirements such as performance, stability and durability. These requirements will have a lasting effect on our mobility in the future. The corrosion risk and the corrosion activity of the reinforcing steel largely define these requirements and are determined by various impact and material parameters. Moisture and corrosion behavior are among the most important of these parameters in interaction with external environmental influences, cause invisible damage inside the concrete structure. The early detection of corrosion activities inside the concrete structure essentially determine the costs for its maintenance and repair.

  • Simple operation & evaluation
  • Wireless & Powerless
  • Remotely accessible
  • Retrofittable

Application: Concrete monitoring

Property: Concrete

Concrete plus steel - this combination stands for simple processing, variety of shapes, economic efficiency, and high load-bearing capacity in supporting structures in all construction areas.

However, it has a natural weak point:
The initially corrosion-resistant reinforcing steel loses its passive protective layer over time due to ageing and chemical influences. As a result, damage occurs, initially unnoticed, which can later endanger the load-bearing capacity of the entire structure. Once pitting, spalling and cracks have become visible, the remediation effort is already considerable.

Our unique cable- and energy-free early warning system, corroDec®2G, offers a simple and cost-effective solution here. Our sensors for corrosion, moisture or potential are inserted or retrofitted at the vulnerable points of the structure. Now the status can be recorded wirelessly at any time, and you receive valuable information about the structure's condition. As a result, you can take timely and targeted action. With our solution, you can sustainably secure the substance and value of your building and, if necessary, renovate it cost-efficiently. You can also effectively monitor the success of a repair measure.

Uncomplicated, cost-effective, and flexible.

CorroDec® sensors can be installed without great effort both before concreting and afterwards, with the help of a core hole drilling. Typical application areas are hydraulic structures, bridges, multi-storey car parks or shaft structures, etc.

CorroDec®2G offers a wide variety of sensor variants, expansion modules, installation options and interrogation paths.

It is, therefore, suitable for almost all types of structures and applications.

The sensors are passive, energy-free and have no cable connection to the outside world. In this way, we ensure an extremely long service life for the sensors and rule out the possibility of harmful factors entering the structure along a cable leading to the outside.

The CorroDec®2G sensor system series is based on the RFID principle. This means that the sensors do not require any power supply or data transfer cables. Instead, the energy for the sensors is supplied by the reader. Furthermore, the data is transferred simultaneously when a sensor is activated. Therefore, it takes only 3 to 5 seconds to collect and evaluate the data of a sensor.

The reader meets the following requirements:

  • High mechanical stability
  • Small and handy
  • One-handed operation
  • Standard reading range up to 10 cm
  • Advanced reading range up to 45 cm
  • Permanent data storage of up to 1,000 sensors
  • Wireless transmission (WLAN) of data to a computer
  • Immediate display of the detected data regarding the status (sensor detected + sensor OK)
  • Parking garage
  • Bridge structures
  • Elevated tank
  • Tunnel
  • Sewage treatment plants
