Cathodic Protection

What is cathodic protection?

Cathodic protection is a technique used to control the corrosion of metal by making it the cathode of an electrochemical cell. Concrete assets are often reinforced using metal bars, therefore it is crucial to protect the metal from corrosion so it continues to offer the required support.

Freyssinet offers inspection and concrete testing services to assess and diagnose issues and provides innovative design solutions and CP installation. With extensive expertise in concrete repair, Freyssinet is able to deliver a complete asset repair and protection package.

Cathodic protection testing, inspection and installation is carried out by qualified engineers who ensure quality control systems are established for accurate reporting on asset management.

Routine cathodic protection monitoring is key to controlling long term repair and maintenance costs on such structures. Monitoring can take place above and below ground systems to ensure correct corrosion protection is in place and operating efficiently, and detailed monitoring reports are issued, highlighting any corrosion issues which enables remedial works to be prioritised.

Corrosion prevention is key to the asset protection of both old and new build structures. Undertaking the investigation and diagnosis of corrosion-related deterioration, Freyssinet Corrosion Control Services carries out work on reinforced concrete structures, historic and steel-framed buildings, ports and harbours and immersed pipelines.
