In this study, Cavities in Specimens were find using GPR equipment. Results of exploration deadline for plain concrete, reinforced concrete, asphalt, gravel, depending on the type, asphalt pavement was most clearly exploration. Developed GPRiPP can represent a good cavitation through the image processing with the background removal.
