Structural engineer should investigate the existing concrete members and collect all possible information to diagnose the safety and serviceability conditions before commencement of any repair or strengthening procedure. The amount of steel corrosion, member deformation, deflections, cracking, vibration, material defects and member capacity should be identified in order to choose the best rehabilitation scheme. The rehabilitation process should start with repair of the existing members including removal of steel corrosion, steel protection and crack injection, possibly rectifying member deformations/deflections, and maintain good quality concrete. The concrete substrate should be cleaned from any loose material or debris, and the jacket should be installed on rough and sound surface. The concrete roughness shall be reached using either sand blasting, water blasting or equipment producing low vibration. No sledge hammer or pneumatic hammer of large weight (more than 10 kg) should be used in order not to create surface/internal cracks in the concrete substrate.
