Ground Penetrating Radar and Utilities Mapping

To determine the position and depth of underground utilities we use a combination of Ground Penetrating Radar (GPR) and Radio Detection. This approach drastically improves the chance of detecting all utilities -including utilities made of non-conductive material- in the area under survey.

Once the field work is complete we are able to produce the following reports:

• Autocad drawings showing the utilities position, type and depth
• GPS coordinates of utilities which can be viewed in Google Earth
• 3D images taken with the GPR equipment of the underground utilities
• Marking position, type and depth of utilities onsite using high visibility spray paint

Other application of ground penetrating radar include:

• Mapping of voids or cavities beneath roads, pavements, runways and behind tunnel walls
• Detailed Inspection of concrete structures, determine location of steel reinforcing bars and pre- and post- tensioned cable ducts. GPR can be used in 3D mode to map multiple layers of steel in buildings.
• Determine thickness of road layers
