Nowaday, Cast in Place Concrete Pile is adopted to basements, which have large amount of load is applied. But, due to Imperfect means of Integrity test methods, safety risk of stability to piles and upper structures grow up as time goes by. This study is aimed at suggesting methods of checking stability of the internal concrete and identifying size and shape of the cracks by using one probe which has the ability to send and receive longer than 50kHz ultrasonic waves and several ones.
