Corrosion Control

Concrete structures such as bridges and towers are typically built in harsh environments where corrosion control can play an important role.

Chloride ions can cause damage to the passive film on steel reinforcement used in reinforced concrete structures, entering from de-icing salts or from seawater in marine environments.

This in turn causes corrosion, which without attention can weaken the integrity of a concrete structure or cause cracking, spalling and delaminating of the concrete.

Typical methods of corrosion control employed by us are:

Cathodic protection – working closely with Concrete Preservation Technologies we can offer an innovative and flexible range of products that effectively treat steel corrosion problems on a wide range of reinforced concrete structures.

Migratory inhibitors - which are generally applied to the external face of the concrete surface.
Sacrificial anodes - applied to the exposed rebar following breakout of defective concrete
High-grade anti-carbonation coatings - normally used where low cover of concrete has been established over rebar - this can chemically aid with increasing cover.
