Corrosion Control in Concrete Structures

Electrochemical protection methods have become a widely recognised and highly effective solution for the long-term repair and maintenance of reinforced concrete structures. Among these, cathodic protection is the only practical approach to prevent ongoing chloride-induced corrosion of steel reinforcement, which is one of the primary causes of deterioration in concrete worldwide. By applying a controlled electrical current, cathodic protection halts the corrosion process, extending the service life of structures and reducing the need for repeated, costly repairs. When combined with thorough condition surveys and well-designed repair strategies, electrochemical methods provide a sustainable, durable, and cost-effective approach to corrosion management, particularly for heritage, marine, and high-value infrastructure projects where structural longevity is critical.

The presentation, Corrosion Control in Concrete Structures, will introduce CRL, the sectors in which we operate, and the full range of services we provide. It will cover the fundamentals of corrosion, including why and how it occurs in concrete structures, and the effects it has on structural integrity. The presentation will also explore the broader implications of corrosion, both at a structural and global level, before examining strategies to combat corrosion. Attendees will gain an understanding of cathodic protection, including the different types available on the market, and see examples through selected case studies and projects undertaken by CRL.
