Using the latest Ground Penetrating Radar technology
AUSTRALIAN SUBSURFACE can
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 Wombat habitat near Captains Flat to confirm that a pipeline installation would not disturb the habitat.
Other Geophysical Survey Applications - These applications include: Forensic Evidence Locating & Cemetery/Gravesite Mapping .
Locate UST'S- For (UST) underground storage tank locating a considerable amount of time and expense can be saved to locate tank non-destructively utilizing our GPR services. We are also able to identify and confirm the location of a previously buried drum even after it has been removed. If the underground storage tanks are buried below concrete or asphalt we can also tell you how thick the surface is and whether it is supported with rebar reinforcements... BEFORE YOU START DIGGING.
Our clients include companies and individuals who may be required to confirm if an underground storage tank is buried subsurface prior to the transfer of ownership. From the new owner's stand point it is important to identify the risk of a large environmental clean-up bill to remove the tank and the expensive task of cleaning the soil if it has been contaminated. We also work with Environmental Companies for larger commercial non-destructive testing geophysical applications.
Using Ground Penetrating Radar (GPR) we can locate Underground Storage Tanks (UST) and any associated underground piping. This non-destructive inspection and geophysical survey can determine the location and depth of a UST or provide the location of a former tank vault. We can mark on site the location of an existing or deteriorating tank prior to drilling or excavating operations.
