Detect corrosion before it becomes visible
Moisture and chlorides destroy concrete and reinforcement from the inside. With passive, energy-free CorroDec 2G sensors, you detect capillary moisture, chloride fronts and corrosion risk early enough to act in a targeted and cost-efficient way.
Why moisture and corrosion monitoring
Why moisture in the component is so dangerous
Concrete and steel form an economical and resilient combination, with one natural weak point: moisture and chlorides destroy the protective passive layer of the reinforcement steel over time. The damage develops unnoticed inside the structure, long before spalling and cracks become visible on the surface.
Request a quoteLoss of the passive layer
Chlorides and persistent moisture dissolve the corrosion-protective passive film on the reinforcement steel. The steel begins to rust, initially completely hidden.
Early warning instead of a refurbishment case
Once pitting, spalling and cracks become visible, the refurbishment effort is already considerable. Monitoring detects corrosion activity before it becomes a hazard.
Moisture trend in the concrete
The moisture sensor measures the electrical conductivity and temperature inside the component and delivers a reliable trend of how the moisture develops.
Chloride and corrosion risk
The corrosion sensor monitors, using a continuous sensor wire in two levels, whether corrosive influences reach the reinforcement steel.
Preserving the value of the asset
Whoever knows the condition can refurbish in a targeted and cost-efficient way instead of across the board. This sustainably protects the substance and the value of the structure.
Evidence and control
The monitoring documents the quality of a new build and objectively tracks the success of a repair over years.
Simulation
The moisture traffic light in the component
Follow how the capillary moisture moves into the concrete and the chloride front reaches the reinforcement steel. The traffic light shows the corrosion risk at every stage, exactly what the sensor captures in the real component.
Condition
Dry
No risk
The concrete is dry, the passive layer of the reinforcement steel is intact. Sensor wire level 1 and 2 are both in order.
How CorroDec 2G works
A passive, energy-free early warning system for concrete
The CorroDec 2G sensors are installed at the at-risk points of the structure, either during construction or retrofitted. They are passive and energy-free and have no cable connection to the outside. This ensures an extremely long service life and rules out harmful substances entering the structure along a cable. Only the reader supplies the sensor with energy when it is queried.

Corrosion sensor
A continuous sensor wire is destroyed by corrosive influences. Read out are wire level 1 in order yes or no, level 2 in order yes or no, and the temperature in the concrete.

Moisture sensor
Two stainless steel rings measure the electrical conductivity and temperature in the concrete and deliver a reliable trend of the moisture development.

RFID readout
The reader works on the RFID principle. In 3 to 5 seconds it delivers condition and readings, without any cable and without a battery in the sensor.

Online 24/7
Through the system extension for remote readout, the data is transmitted via Narrowband (NB-IoT), visualised and an alert is triggered if a threshold is exceeded.

Stress corrosion cracking
Moisture and chloride are the precondition
Stress corrosion cracking (SCC) only occurs when two things come together: permanent tensile stress in the prestressing steel and a corrosive medium such as chloride or moisture. The second condition is the one that can be measured directly in the concrete, before it takes effect. The damage itself then proceeds inside the structure and only becomes visible through the deflection of the superstructure.
