Global GPR offers a geophysical survey imaging service for non-destructive testing (NDT) evaluation to locate and map subsurface features. Using Ground Penetrating Radar (GPR) Global GPR uncovers the mysteries below the ground. The depth of exploration is determined by the ground penetrating radar frequency, ground make up, soil conditions and type of target to be identified.

Common Geophysical Survey Applications:

Identify Subsurface Layers - To map the depths of various soil compositions for mining applications. Geophysical surveys are also used to locate water tables or the depth of bedrock prior to drilling or excavation.

Locate Subsurface Voids - To map the depths and locations of voids in the ground, below road surfaces or below concrete slab floors before they become a dangerous Sink Hole. A GPR geophysical survey is less invasive than taking core samples to determine the depth of a void or multiple core samples to determine the overall size of the void.

Archaeology Survey - Subsurface objects and stratigraphy (layering) will cause reflections that are picked up by GPR equipment. The travel time of the reflected signal indicates the depth. Data may be plotted as individual profiles, or as maps isolating specific depths.

Environmental Assessment - GPR technology has may non-destructive testing uses in the area of environmental asessment. Depending on soil conditions ground contamination, buried objects and water tables can be mapped. Animal habitats can also be mapped. We used this technology to map a Prairie Rattlesnake habitat in southern Alberta to confirm that a pipeline installation would not disturb the habitat. (READ WHITE PAPER)

Other Geophysical Survey Applications - These applications include: UST Locating, Forensic Evidence Locating and Cemetery & Grave Site Mapping. Detailed information about these applications can be found by clicking the above links.

Some individual targets can be identified on site in real time. Mapping a survey can be accomplished relatively quickly by taking the GPR information collected on site, analyzing the data and mapping the results in our lab. This makes a ground penetrating radar geophysical surveying one of the most efficient and cost effective methods for many geophysical surveys.
