There are cases in which crack and peeling are generated in the concrete structures. The repair and reinforcement of the concrete structures will inject repairing materials in the concretes. As the result, the structures become the prolonging life. However, there is no report of how repairing materials are injected into the crack divisions and the peeling divisions. The repairing materials were injected into the cracks in this study. The injection behavior was examined by rectangular diffraction method of the ultrasonic wave test. In the cracks, the filling of repairing materials can be evaluated by the direction and amplitude of the first wave of receiving wave. These waveforms from the abnormality divisions equal to the waveforms of the soundness divisions, when the repairing materials were filled at the crack divisions.
