Ground Penetrating Radar (GPR)

Ground penetrating radar (GPR) uses radar pulses, propagated into the ground from either a cart or a sled mounted antenna. When these radar pulses encounter an interface of materials with different dielectric properties some of the radar energy is reflected back to the surface and may be detected by the GPR system.

One of the benefits of GPR over some other techniques is that GPR has the potential to detect non-metallic as well as metallic features.

In recent years GPR may have been used as a buzzword, and in some areas, it has been used as a substitute for the type of survey a client may require, such as a utility survey or a geophysical survey.

Rather than using GPR as a stand-alone approach, we normally recommend using all appropriate technologies available to us to form a multi-technique methodology that has the best potential for achieving comprehensive results.

Terravision has various ultra-wide bandwidth GPR systems for use on different terrains. We have in-house capability for both the on-site interpretation and off-site post processing of GPR data.

Combined with electro-magnetic location, metal detection, magnetometry and, crucially, the expertise of qualified and experienced professionals, GPR can help build a picture of utilities positions, buried chambers or manholes, subterranean structures, concrete reinforcing, previously excavated or disturbed ground, changes of subsurface material, near surface stratigraphy, voids, obstructions, and much more besides.
