Cathodic Protection - Corrosion Treatment

Corrosion of infrastructure is an inescapable reality. When the diagnosis reveals an advanced state of corrosion, cathodic protection becomes essential to stop its propagation and damage to structural elements that endanger users.

We rely on recognized and certified skills to offer reliable and efficient equipment in terms of cathodic protection, which guarantees the longevity of your structures.

Discover the product

Bluespine manufactures high-tech cathodic protection equipment, designed to meet normative requirements for performance and durability. Our innovative technology offers a complete solution tailored to your needs. 

Cathodic Protection controller


  • Reinforced or prestressed concrete

  • New structures for prevention

  • Old structures for treatment

  • Engineering works or buildings

  • Corrosion due to carbonation or chloride pollution

  • Compatible with all structural repair solutions

  • Compatible with all ICCP anodic systems available on the market

BSCP-100's function

  • Ensures, regulates and controls the power supply to the zones to be protected.

  • Measures and collects all required normative current and potential data, as well as additional data from various sensors (temperature, humidity, pH, etc.), to thoroughly evaluate the performance of the installation.

  • Evaluates the performance of the cathodic protection installation by carrying out a synchronized cut-off of all the anodic zones to carry out the examination of the 3 normative criteria (EN ISO 12696).

  • Generates normative reports and alerts the operator in the event of incidents or defects.

How it Works

Tailor-made solution adapted to the needs of the structure, regardless of the number of anodic zones requiring protection.

  • For each anodic zone, the reinforcement to be protected is connected to the negative pole (black) and the anodic system (Activated titanium or electro-conducting carbon coating) to the positive pole (red) of the cathodic protection PLC.

  • The reinforcement undergoes cathodic polarization (potential drop), which is evaluated via reference electrodes and depolarization probes. The EN ISO 12696 standard specifies the minimum number of measurements to be made per anodic zone.

  • The PLC is connected to the grid or powered by a system of solar panels and batteries whenever possible.

Some of the advantages of using the BlueSpine cathodic protection controller

Tailor-made cathodic protection PLC

Our cathodic protection controller is designed to suit all projects, regardless of :

  • The number of zones requiring protection

  • The variety and quantity of measurements needed (current, potential, temperatures, ...)

  • The configuration into one or multiple cabinets

  • Adaptation to the structure’s age and environmental factors (aggressiveness, temperature, etc.)

Reliability and durability BSCP-100
Reliability and durability 
  • Cabinets and connectors : 

    • IP66 Class to prevent electronic component degradation from dust and moisture.

    •  IK10 Class to withstand shocks and vibrations during transportation, installation, and service life.

  • Electronic board coating with thermo-conductive polymer :

    • Uniform heat dissipation. ​

    • Protection against corrosion. 

  • Controlled hygrothermal environment: temperature and humidity regulation regardless of external conditions.

  • Lightning and surge protection: Power supply protection ensured by a 1+2+3 monoblock lightning arrester and Transil diode devices.

Remote monitoring
  • Intuitive control: ergonomic full web interface for easy monitoring and remote control of the installation.

  • Secured data : 

    • Alerts in case of incidents or hacking attempts.

    • Double authentication for secure monitoring.

    • Encryption of communication buses and storage on highly secure servers.

Anodes for impressed current cathodic protection (ICCP)

Anodes titane activé BlueSpine pour la protection cathodique à courant imposé
Activated titanium anodes
  • In mesh, ribbon or drilled, our anodes are adaptable to all the needs of the work regardless of its geometry or pathology.

  • Activated titanium provides the highest level of corrosion protection throughout the lifetime of the installation (up to 220 mA/m² over 50 years).

  • Robust anodes thanks to : 

    • their Level 1 titanium composition according to ASTM-B-265 for maximum mechanical strength.

    • their precious metal oxide (MMO) coating making them resistant to all environments, even the most aggressive.

Electro-conductive coating anode
  • A powerful and reliable anodic system thanks to its high carbon content:

    • ​Uniformity of cathodic protection current distribution. 

    • Limitation of the risk of over-polarization.

    • The primary layer, composed of aluminum silicates, provides better carbon adhesion to the structure and thus ensures the durability of the anode. It causes a buffer effect between the concrete and the anode, thus limiting the undesirable acid effect at the anode.

  • Suitable for large areas to protect, this solution offers great simplicity of implementation: 

    • Reduction of the number of openings in the work.

    • Low weight compared to other anodic systems, adapted to unique structural constraints. 

    • Applicable in roll as in air-spray, for maximum time saving.
