Ground Penetrating Radar (GPR)

Ground Penetrating Radar, also known as GPR, is a tool that is used to find anomalies under the ground surface. GPR can sometimes be ideal for locating non-conductive underground utilities, underground storage tanks (USTs), as well as other underground structures without any surface connection, or access points, The depth and accuracy of GPR data results are dependent on a number of variables, such as soil density, moisture content, and antenna frequency. We use 400-500 MHz antennas in our GPR units, which can reach depths of up to 15 ft (in perfect soil and terrain conditions)

 

(GPR) is an important tool in locating buried utilities, structures and other anomalies.  We use GPR primarily for locating non-metallic utilities. This tool is also used for finding changes in subsurface conditions (trench lines) or underground storage tanks (UST’s). GPR's advantage is finding non-metallic and untraceable plastic pipes or conduits. GPR has some limitations. Interpretation of the data by a skilled technician is essential. GPR readings are limited in highly conductive soils, such as clay.
