Ground penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF) of the radio spectrum and detects the reflected signals from subsurface structures.
GPR can be used in rock, soil, ice, fresh water, pavements and structures to detect objects, changes in material, voids and cracks.
What is Ground Penetrating Radar?
- Ground penetrating radar uses an antenna pair (transmitter an
d receiver separated by a small fixed distance) to send short pulses of electromagnetic energy into the subsurface and record the returning signals.
- Images are projected on a monitor depicting the location and depth of targets identified.
- Multiple GPR antennas on one platform allow the creation of 3D images of the subsurface for even more complete mapping.
- BHATE utilizes GPR as well as various other geophysical methods, to locate subsurface targets. We apply this technology to utility locating and mapping, geologic inspections, underground storage tank (UST) locating, forensic investigations, bridge and roadbed inspections.
What GPR Solutions Does BHATE Provide?
- Structure Scan – GPR technology can save builders, contractors and architects time and money by allowing for structural reinforcements and utilities within concrete slabs and columns to be mapped. Our GPR technicians are trained on how to spot the difference between steel and nonmetal conduits, as well as identify corrosion in rebar.
- Utility Location – While One Call utility locating services can be useful, GPR provides extreme precision when locating the position of a utility line, which is important when preventing line strikes. GPR can find unmapped utility lines and underground storage tanks (UST), which can prevent your company from being liable for accidental releases of hazardous substances. BHATE can precisely locate utility lines identified with GPR and overlay them onto a CAD file for your future use.
- Geologic Investigations – BHATE provides low-cost, non-intrusive means of subsurface investigation for our clients. Our GPR technicians perform detailed geologic analysis and work with clients in helping them understand their site and the implications of our findings. Our GPR experts have experience identifying voids, sinkholes, depth to water table, septic tanks, steel drums, underground storage tanks (UST), depth to bedrock and various other buried objects/structures.
- Roadbed and Bridge Deck Analysis – BHATE owns multiple systems for the collection of multichannel GPR data including handheld, walk-behind and vehicle-mounted GPR devices. Vehicle-mounted GPR can be used at traffic speeds for both the measurement of pavement structure thickness, as well as identifying areas of relative deterioration on bridge decks. Air-launched GPR systems are not connected to the ground surface and are capable of collecting data at speeds of up to 65 MPH without disrupting other road users.
