Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR) is used to detect subsurface features and objects.

The machine rests on collapsible and highly portable three-wheel cart that is pushed over the surface. A radar signal from an antenna passes into the ground and reflects off objects under the ground. The information is displayed on a screen providing real-time views. Mapping subsurface utilities: GPR, sondes, cable/pipe locator and CCTV is used to create a “map” of underground services. One instrument on its own cannot provide the accuracy needed for such a survey.

Possibilities with GPR

• Environmental Impact Assessments: locate sub-surface objects, water table mapping
• 2D & 3D imaging
• Locate pipelines, cables, ground disturbance, tanks & voids
• Roads: evaluate base & sub-base levels, voids, layer thickness
• Forensics: locate clandestine burials, hidden caches of weapons
• Geology: mapping sand & gravel beds, bedrock horizons
• Pre-development: Before excavation: location of pre-existing disturbed ground, locate municipal services, fibre optic cables, etc
• Agriculture: soil conditions and bedrock
• Archaeology: non-invasive investigation of site area, reduces investigation time.
• Concrete studies; locate re-bar spacing and depth in concrete.
