Stopping steel from rusting - inside concrete, underground and underwater.
Corrosion control keeps steel working in the places it naturally wants to dissolve: reinforcement inside chloride-soaked concrete, buried pipelines, marine piles, sheet-piled walls and storage tanks. The heavyweight tool is cathodic protection - impressed-current or sacrificial-anode systems that make the steel electrochemically immune - alongside protective coatings, linings, wrapping systems and corrosion inhibitors.

Corrosion Control & Cathodic Protection in depth
About Corrosion Control & Cathodic Protection
It is a design-install-monitor sector: a cathodic protection system is commissioned against measured potentials and then monitored for the rest of its life, which makes it as much an instrumentation discipline as a coatings one. On concrete structures it is often the only alternative to demolishing chloride-contaminated decks that are otherwise sound.
