We developed a string shoot impactor with a small stainless ball attached to the string of a string shooter for generating impacts. This impactor can remotely inspect walls. We applied the impactor to 70 mm × 70 mm and 70 mm × 145 mm tiles, and successfully detected tile delamination, as well as raised tiles due to mortar failure. The test conditions were as follows: the distance between the specimen and the impactor was about 50 cm, the diameter of the ball used for the impact was 4 mm, the ejection velocity of the ball was 10 m/s, and the movement speed of the impact point on the inspection surface was 50 mm/s.
