Ground Penetrating Radar technology can effectively be used for many applications. One of the most helpful applications is the ability to locate and distinguish subsurface features and utilities including cables, pipes, concrete reinforcements and underground storage tanks. Excavated areas, back-filled areas and other types of ground disturbances can readily be identified and mapped. On a smaller spatial scale, Ground Penetrating Radar works extremely well at detecting and inspecting fractures and faults in building materials, roads and bridges. GPR has also successfully been employed in the investigation and characterization of subsurface and subsurface features in fields including environmental detection, surficial geology, forensics and archaeology. The following is a brief list of the more common uses of Ground Radar:
Utility Service Locating
Ground Penetrating Radar is currently the only non-destructive technology able to locate both non-metallic as well as metallic subsurface utilities. It is ideally suited for locating utilities including water, sewer, gas, electric, telephone, cable and fibre optic. By identifying the location and positioning of services before beginning construction and excavation, the possibility of costly damage as well as safety risks to workers is greatly reduced or eliminated.
Ground Penetrating Radar works extremely well at visualizing concrete floors, walls, decks, slabs, tunnels, balconies, warehouses and garages. It is able to locate rebar, tendons, conduits, and voids, as well as measure slab thickness. Generally this is done with access to only one side of the element. It is vital to have knowledge of the position of obstructions within the concrete before drilling, cutting or coring.
Roads, Runways and Pavement Surveys
Ground Penetrating Radar has the ability to determine pavement thickness (asphalt and concrete), detect voids beneath road pavement, identify de-bonding between layers and distinguish layer thickness.
Ground Penetrating Radar can be utilized to locate underground storage tanks (UST), grave locations, and other buried objects. It also works extremely well as an aid in forensic investigations.
In addition to successfully locating buried pipes, drums, and underground storage tanks, Ground Penetrating Radar can also be applied to locate and determine the extent of leakage and contamination. In the same manner, the degree of landfill sites can also be determined.
Ground Penetrating Radar is an excellent tool for the location, investigation and determination of the extent of footings and foundations. The quantity of trial pits (test pits, pot-holes) essential to determining foundation and footing detail may well be greatly reduced, saving time and money.
Ground Penetrating Radar may be used to map the subsurface with the intent of identifying and preserving items such as possible archaeological artifacts, bones, etc.
