Cathodic protection (CP) is a very well established technology for the long term corrosion protection of structures suffering from chloride contamination problems. Achieving the optimum design and installation of CP systems is a challenging task especially for complex applications.
The most critical part of CP systems is that the bulk of the system will be embedded in concrete once the installation is completed. As a result, every aspect of the design and installation must be completed correctly the first time. Underestimation of the current density required to achieve protection, incorrect arrangement or selection of anodes to achieve adequate current distribution and eliminate defects such as grout deterioration, failure to establish 100% steel continuity, incorrect system zoning, failure of anode or steel connections, poor selection of reference electrodes or where to place them, or poor selection of the control system may have a very negative impact on the performance of the CP system, its maintainability and its capacity to protect the structure adequately.
To get it right from the first time, there is no substitute for extensive experience we have at FixART.
