Request for the development of non-destructive test (NDT) techniques have improved with the growing concern about the deteriorating condition of concrete structures. Efficient and accurate imaging techniques are needed for a reliable evaluation on safety and serviceability of concrete structures. Although, presently, imaging is routinely conducted in various fields, implementation of these technologies in NDT of civil engineering systems, especially on concrete structures, offers many challenges and requires additional development due to the composite nature of the concrete material and the complexities of reinforced concrete systems. In this paper, the feasibility of visual observation device that developed with small inspection borehole for investigating internal crack in concrete structure by scanning technique is presented. Special considerations regarding the applicability and accuracy of these techniques for the condition assessment of concrete structures are discussed, and examples of field application are given. © 2006-2012 Asian Research Publishing Network (ARPN).
