Cathodic protection

Gordon St Randwick Structural Repair

 

A possible cause of structural decay is ‘concrete cancer’. This is caused when water and contaminants seep into concrete and react with the steel reinforcement. The steel reinforcement corrodes and the concrete structure is weakened. To prevent this from happening cathodic protection can be employed.

Cathodic protection uses an anode to apply a current to the reinforcement. The steel reinforcement then becomes cathodic and as such resistant to corrosion. This cathodic resistance against corrosion decreases the chances of concrete cancer and potentially increases the structural life of your building or structure.
