Concrete protection also means protecting the embedded steel bars from corrosion. This can be done by applying a protective layer on the reinforcement, by using corrosion inhibitors or by cathodic protection. Cathodic protection is one of the most effective means of protecting embedded steel bars in concrete and preventing corrosion. It is an electro-chemical technique to stop steel corrosion by galvanic anode or induced current. Sika proposes a full range of anodes (galvanic and hybrid anode systems) to prevent the onset of incipient anode corrosion and to control corrosion in contaminated but sound concrete.
