Ground Penetrating Radar (GPR) Below-Ground Exploration and Inspections
GPR is a non-intrusive (no digging or drilling required) method of determining if objects such as Underground Storage Tanks, old utility lines, gravesites, archeological sites, or foundations are located at a specific location below the ground's surface.
The use of GPR for locating underground objects is limited only by one's imagination and by certain physical limitations of the GPR equipment itself.
In the Central United States, including Kansas and Missouri, GPR's depth range is effective to:
Approximately 5 feet if clay soils are used as fill over the buried object;
To 15 feet if gravel or sand is used as fill.
GBA uses the Geophysical Survey Systems Inc. SIR 2 GPR unit, with three seperate radar antennas available depending on the requirements of the specific job and depth of the underground object.
This unit produces real-time results viewed on a radar screen and stores the information on a built-in computer for later download and record of the survey or inspection. No GPR unit will work through standing water more than one-inch deep; therefore, wet-weather is a factor in scheduling a GPR survey.
