The works that took place were removal of the loose concrete, sandblasting and cleaning of the corroded reinforcement, application of corrosion inhibitor onto the reinforcement, corrosion inhibitor coating on the concrete surface, concrete restoration with repair mortars R3/R4, strengthening using shotcrete jacketing, strengthening with FRP, and application of final paint coatings suitable for limiting carbonation.
Where the chloride content inside the concrete was above the allowable limits, special techniques and materials were used to reduce this content.
The process followed and the materials and systems used were in accordance with relevant standards (mainly EN 1504) and the Greek Technical Guidelines (ΕΤΕΠ).
