Defects occur due to material failures, application failures, deterioration, environmental effects and abrasion damages partially at some elements or at the whole structure. The most common failure is the cracking or spalling of concrete resulting from the corrosion of the steel reinforcement.
- Remove defective concrete up to sound concrete, expose corroded reinforcement
- Clean the concrete and corroded reinforcement using blasting techniques or by other suitable means
- Reprofile repair area using polymer cement concrete (PCC, cementitious polymer modified repair mortar) or polymer concrete (PC, resin based concrete)
- Surface protection of the concrete according to the requirements of the element: protections against the ingress of moisture, improvement of the mechanical, physical resistance and chemical stability.
The removal of defective concrete will be executed with approved materials and methods according to the European standards, Code of Practice for the Protection and Rehabilitation of Concrete Elements and it’s quality and testing methods.
