[en] Since concrete has been used for more than a century, many structures need repair in different degrees and others need strengthening to withstand higher loads. Moreover, the number of new concrete structures is constantly increasing, and therefore repair or retrofitting requirements increase. Present concerns of sustainable development emphasizing repair or strengthening instead of new construction, acts as incentive to this trend.
The bonded overlay technique is particularly suitable in the case of structures with large areas like industrial floors. This paper has the ambition to present reliable design methodology for the practitioner. Surface preparation, overlay design and material selection, application process and QC/QA are discussed and guidelines are proposed in order to enhance quality of repair operations.
