Exterior wall tiles risk delamination with time-related deterioration. To prevent exterior wall tiles from falling, a full inspection of the building must be carried out every 10 years. A visual inspection and an impact acoustic inspection by workers are used to evaluate the condition of buildings. These inspections need scaffolding, aerial work vehicles, and workers' labor costs. For residents, the cost of inspections is an excessive burden. Therefore, there is a need for a reliable and low-cost inspection method. In this study, we developed a rotating hammering device that hits the wall surface at high speed. To prevent the chipping of tiles caused by hammering, the resin was used as the hammer. The performance of the hammering device was evaluated by verifying the stability of the impacts and the performance in defect detection. As a result, we verified the effectiveness of the hammering device using a resin hammer.
