The development of a nondestructive inquiry in civil engineering enables us to observe things lying underground without digging the field. The purpose of this research is to measure the drain culvert in our school campus by using underground probe machine (ESPAR V2). This is a nondestructive inquiry. Consequently, the position of an object in underground was measured by the electromagnetic radiation method based on the time difference between the incident wave and the reflected wave.
