In order to extend the service life of bridges, we will introduce products that accurately grasp the damage and deterioration status of structures and perform appropriate repairs in a timely manner.

Inspection/survey/diagnosis

CoroCoro eye ®
(Rotary tapping sound checker)

It is a tool to detect abnormal parts inside concrete from the change in impact sound generated by moving and rotating a metal polyhedron against the concrete surface.
