What is Ground Penetrating Radar (GPR) ?
GPR is the process by which a radar wave is directed into the structure or the ground and the resulting reflection is collected and analyzed by the technician. The latest powerful software
processes the collected data into either 2D or 3D images which can then inserted into reports or presentations.
What can be located?
Almost anything can be located providing the object is large enough in relation to the frequency of the antenna and that there is sufficient contrast between the electrical properties of the object and its surrounding material.
Is it Safe ?
GPR generates less power than a standard mobile phone and at similar frequencies and can therefore be used in any environment deemed safe for mobile phone operations. Unlike X-Ray which requires evacuation of people within a 20 metre radius around and below, GPR causes little or no disruption to other people working within the vicinity
Where can it be used?
GPR can be used anywhere providing the surface over which the survey is being conducted is reasonably flat and has no surface water. Our equipment is light and versatile enough to allow surveys to be conducted almost anywhere, whether it be floors, walls, roads or fields. Sizes of surveys are tailored to the Client’s needs.
How deep can we see?
Depth of surveys are dependent on antenna frequency and attenuation of the transmitted radio wave. Antennae which have higher frequencies will give an image with better resolution but lack the penetrating depth of lower frequency antennae. Attenuation is the ability of the material being surveyed to absorb the the radio wave. The greater the rate of attenuation, the lower the ability of the radio wave to penetrate the material. Test surveys need to be done in order to assess the penetrability of the radar signal.
