Maintenance and Expertise

The technical department of COREXCO ensures the maintenance of existing cathodic protection systems and makes expert interventions:

  • Ensure the proper functioning and efficiency of installations
  • Maintenance and systems rehabilitation
  • Corrosion and soil corrosivity studies
  • Detection of coating defects
  • Species Reconciliation Closure (CIPS) ....


We carry out internal measurements for various corrosion needs:

  • Corrosion characterization for different metals
  • Measurement of the rate of corrosion by linear polarization (applicable in sut)
  • Determining parameters of protection
  • Electrode calibration, impedance measurement
  • Production of copper sulphate and silver chloride gel
  • Chlorides, oxygen content (redox) and Ph analysis
  • Measurement of resistivity and presence of bacteria....
