Civil and concrete anodes
Anodes that protect steel reinforcement in concrete and the steel elements of bridges, ports and waterfront structures.
Reinforced concrete, bridges, ports and waterfront structures.
When chlorides from seawater or de-icing salts reach the steel inside concrete, the reinforcement corrodes, expands and cracks the concrete around it. Galvanic anodes embedded in the concrete corrode in place of the steel and slow this process — extending the life of repairs and structures.
For waterfront infrastructure, sacrificial anodes also protect steel piles, sheet piling, dock gates and intake structures where they meet seawater.

E01
Concrete Galvanic Anodes
Zinc anodes encased in an activating mortar, embedded in concrete to protect the reinforcement around them.
-
E02
Discrete Concrete Anodes
Anodes installed in drilled holes in sound concrete to protect reinforcement over a wider area.
-
E03
Embedded Zinc Anodes
Zinc anodes cast into new concrete or repair areas and connected to the reinforcement.

Common questions.
What does a galvanic concrete anode do?
It contains zinc that corrodes in place of the reinforcing steel. Fixed to the reinforcement in a repair or drilled hole, it slows corrosion of the surrounding steel.
Why use anodes in patch repairs?
Repairing one area can accelerate corrosion in the surrounding concrete — known as the incipient anode or halo effect. Anodes at the edge of the repair help prevent this.
Are galvanic or impressed current systems better for concrete?
Galvanic anodes are simple and need no power supply, which suits targeted repairs. Impressed current systems, using MMO mesh or ribbon anodes, are often chosen for large areas or long design lives.
Can you supply anodes for steel piles?
Yes. We supply weld-on and bolt-on anodes for steel tubular piles, H-piles and sheet piling.
