Cathodic Protection for Balconies

Corrosion can destroy the structural integrity of steel reinforced concrete structures such as balconies, walkways, beams and columns. Cathodic protection can eliminate the costly cycle of concrete repairs and repeated assessments due to corrosion.

Corrpro Companies, Inc., the world leader in corrosion control, provides extensive corrosion engineering services and cathodic protection materials for steel reinforced concrete structures. Our fully qualified staff provides engineering, research, inspection, and other consulting services from our 60 worldwide offices.

Concrete cathodic protection systems are designed to address corrosion problems in steel reinforced concrete. The major cause of corrosion on balconies is due to the presence of salt resulting from the exposure to sea water or the use of contaminated aggregate in the original concrete mix. When steel bars in concrete corrode, the formation of rust causes high internal pressures. Tensile stresses are exerted on the surrounding concrete. Cracks develop leading to delamination and spalling of the concrete.

Cathodic protection effectively stops the corrosion process and has been determined by the Federal Highway Administration to be the only rehabilitation technique able to prevent further corrosion in such structures regardless of the salt content in concrete. Cathodic protection of reinforced concrete structures has also been endorsed by the American Concrete Institute (ACI), AASHTO-AGC-ARTBA Task Force 29, and the National Association of Corrosion Engineers (NACE International).
