We record cracks in bridge concrete through close-up photography to support repair decisions and the maintenance of inspection records.
Cracks that occur in concrete components of bridges pose a risk of leading to rebar corrosion, spalling, and a decrease in load-bearing capacity as they progress. However, quantitatively recording "where and to what extent cracks exist" can be difficult with visual inspections alone. This service combines close visual inspections, high-resolution camera imaging, and measurements using crack scales to detail the condition of cracks in bridges by specific areas. We create deformation diagrams, photo archives, and inspection reports, which can be used as foundational materials for determining the need for repairs and for longevity planning. We can assist in situations such as "I want to officially document cracks that have been a concern for some time" or "I want to organize the results of regular inspections."
