The GPR method is a wave propagation technique that transmits and receives electromagnetic waves (EM or radio waves). We have used GPR ground imaging for mapping underground utilities, karst features such as cavities and voids, soil and/or rock layer thickness, fractures in bedrock, lava tubes, underground storage tanks (UST), detecting old foundations, mapping debris or other obstacles to construction. Borehole GPR applications include: soil profile imaging, karst, imaging of embedded concrete or steel (e.g., piles) structures, fault identification, quantification of fracture density and orientation in rock, and detection of other utility-like features (pipes, tanks, etc.). Surface GPR and Borehole GPR methods can be examined in more detail in this section, using the menu bar to the left to click into each method. Included are short descriptions of each method, and the applications for each method.
