◇Radar Survey◇ We conduct surveys to locate rebar, tile, mortar, concrete thickness, and buried electrical conduits. We perform surveys not only for architectural structures but also for civil engineering structures. Additionally, we investigate underground buried objects and voids in the ground. ◇Electromagnetic Induction Survey◇ We perform electromagnetic induction measurements that strongly react to rebar to confirm the position and cover thickness of shallow rebar. This method is used for inspections of newly constructed concrete structures and cover thickness surveys. It is also possible to survey metal fittings and braces behind tiles and boards. In underground surveys, we investigate buried piping and pipeline surveys. ◇X-ray Survey◇ We can visually confirm the location of buried objects such as rebar and electrical conduits within concrete as images. This method is used when the area is narrow or when complex rebar and buried pipes are intertwined. ◇Tap Testing, Visual Inspection, Exterior Wall Repair Work◇ We regularly inspect the tiles and finishing materials of buildings to repair deteriorated areas before they peel off and cause accidents. Furthermore, we believe that not only our company's development but also the growth of the entire construction industry contributes to society. Therefore, we assist in collaborative experiments and research with various research institutions and in the preparation of papers. We also conduct training sessions on surveying for other companies in the same industry to promote the sharing of technology and information.
