Concrete corrosion in seaward walls of marine breakwaters

Most offshore hydrotechnical structures, once completed and put into service, work both above and below the water surface. Modernization, repair or reinforcement of concrete or reinforced concrete structures in constant contact with salt water poses many problems. The most difficult task is to ensure and maintain efficiency, as well as continuity and readiness to work during the renovation of the structure. The paper presents examples of concrete corrosion that can occur in marine breakwaters; the types of impacts are defined, as well as the associated types of corrosion. The main part of the publication consists of actual examples of damage to concrete walls of water side walls of breakwaters, as well as designed repair methods and their implementation. In addition, the Reader can see photographic documentation of the structure showing both the scale of corrosion damage, repair work and the final result
