A method of repairing a steel reinforced concrete structure (100) affected by chloride induced corrosion, comprising: subjecting the reinforced concrete structure (100) to an electrochemical treatment so as to enrich material (102, 120, 140) embedding the steel reinforcement (110) with chlorides originating from corrosion pits (112) in the steel reinforcement; and replacing the material (102, 120, 140) embedding the steel reinforcement (110), which has been enriched with chlorides during the electrochemical treatment, with a repair material (124) that is relatively poor in chlorides.
