Monitoring

Corrosion monitoring focuses on tracking the condition of steel in concrete and determining whether, where, and how quickly corrosion occurs. Because corrosion remains invisible for a long time, measuring is essential to prevent damage.


Why is corrosion monitoring so important?

  • Corrosion causes:

    • cracking

    • spalling of concrete

    • loss of load-bearing capacity


  • Monitoring makes it possible to:

    • detect damageearlyon

    • carry out maintenance in a targeted manner to prevent costly repair measures

    • to demonstrate the performance of ICCP In summary

    • Corrosion monitoring makes invisible deterioration of steel in concrete visible, measurable, and manageable.

By understanding the electrochemical properties of reinforced concrete and measuring the relevant parameters, corrosion can be detected at an early stage. Temporary field measurements, such as surface potential measurements, can provide important information about the condition of the reinforcement, but unfortunately, such measurements alone are usually not sufficient.

The sensor technology and monitoring systems from Solidura are more complex: corrosion current, potentials, resistances, temperatures, humidity, and much more are continuously monitored.

Our CAMUR electronics ensure that you can permanently and in real-time verify the condition of your structure.

CORRO-WATCH

The CorroWatch Multisensor is embedded in the concrete cover of new concrete structures. The sensor measures the most relevant parameters to assess the corrosion condition. It consists of four measuring electrodes made of black steel (anodes) at different positions with a known distance to the reinforcement and a measuring electrode made of precious metal (cathode). The height of the anodes is flexible and can be adjusted to the thickness of the concrete cover. To predict when the reinforcement will begin to corrode, the current between the individual anodes and the cathode is measured. When corrosion begins, the current will increase significantly.

CORRO-RISK

The CorroRisk sensor has been developed for existing concrete structures and is based on the same measurement principle as the CorroWatch sensor for new builds. The sensor ensures that reinforcement corrosion can be predicted well in advance. The CorroRisk sensor is usually placed in the concrete cover, between the surface and the outer reinforcement layer. The measuring electrodes (anodes) are specially designed to be mounted at various, precisely defined depths in the concrete cover.

reference electrode ere-20

ERE 20 is a TRUE reference electrode with a long lifespan. It can be embedded in the cover layer of concrete structures to monitor the proper functioning of cathodic protection and to assess the corrosion state in reinforced steel. The reference electrode can be installed in both new and existing structures. The ERE 20 is based on known battery technology and is a noble half-cell, which uses manganese dioxide in a very alkaline (pH 13.5) electrolyte, housed in a stainless steel casing and with an ion membrane of cement mortar that ensures good affinity with the concrete.
