The Ground Penetrating Radar (GPR) Service

Ground Penetrating Radar (GPR) is a flexible, transportable, powerful, dominant and one man operated device used to detect underground structures and anomalies. The detector utilizes an omnidirectional unshielded transmitting system to locate hidden items up to maximum depths of 40 meters. All recognized irregularities and underground objects are displayed instantly on screen of an Android Tablet or PC.

Applications and detection capabilities

 Construction Engineering InspectionThe ground penetrating radar is very useful and can be used for many different applications. Its portability and easy handling makes Ground Penetrating Rader(GPR) the perfect device for underground assessments, in archaeology, utility, mining, energy, construction, infrastructure and other related fields.  No matter what kind of concealed objects you are looking for - as long as these items and structures aren't too small and of different material than the surrounding soil - the Ground Penetrating Radar(GPR) can assist you in finding those targets easily and comfortably.

The Ground Penetrating Radar(GPR) can be utilized for a wide range of applications like 

• Construction -Know whats underground before you dig

• Utilities - Locate utilities underground

• Oil and Gas

• Bridge Inspections

• Concrete inspections

• Archaeological investigations

• Industrial/Construction assessments

• Treasure Hunting

The Ground Penetrating Radar (GPR) is able to identifysubstances and structures like 

• underground foundations, walls, basements and concrete reinforcements

• hidden cavities, graves and sepulchers

• buried drainage systems, feed lines, pipelines, conduits and cable harnesses

• water level and underground rivers and aquifers

• backfilled wells, galleries, trenches and dugouts

• septic tanks, distribution boxes and drainage pipes

• secret tunnels, bunkers and shelters

• buried treasure chests, statues and caches

The Ground Penetrating Radar (GPR) works with a numerous transmission frequency range starting at 60 MHz up to 300 MHz which is understood by adjustable telescopic antennas. It also supports countless automatic adjustments to optimize your ground surveys on specific soil categories, which makes the handling of the Ground Penetrating Radar (GPR) very cool. So a non-destructive field examination is easily possible.

You just need to set your depth resolution and start surveying. The Ground Penetrating Radar (GPR) remotely sends a signal into the underground and anticipates the echo which will be receivedremotely by the antennas to indicate the disturbance in the underground. These reflections will be measured and transferred to a Android Tablet or PC.

Ground Penetrating Radar (GPR) Power source

The Ground Penetrating Radar (GPR) is powered by 8 AA batteries or - alternatively - by an optional external Power Pack for long lasting measurements. The Ground Penetrating Rader(GPR) itself has not many controls except one button and the depth regulator, which is used to adjust the maximum penetration depth of the ground penetrating radar service.

But on a final note how Deep Can It Goes?

This is perhaps one of the most frequently asked questions. In most cases an estimated depth range can be determined with accuracy based upon the subsurface material and the frequency of the Ground Penetrating Rader(GPR) antenna. For applications demanding higher resolution, such as locating rebar or conduits in concrete, a sophisticated frequency Ground Penetrating Rader(GPR) system (1,000 MHz) is used. This will give high resolution detail for down to roughly 24 inches in depth. Applications which require deeper penetration in ground soil requires a lower frequency (12.5 MHz to 500 MHz). Depending on the subsurface material the depth range can be from a few inches to thousands of feet.

Infrastructure Preservation Corporation, IPC is a nondestructive testing and robotic engineering company that utilizes ground penetrating radar, GPR in BridgeScan® bridge inspection services. BridgeScan® conducts a condition assessment of the entire bridge deck and approach roadway that goes way beyond gpr alone and is much more comprehensive that current manual inspections using the visual methods and chain dragging.
