Ground Penetrating Radar (GPR) surveys have become the gold standard in subsurface investigation. American Geophysics Inc. incorporates (GPR) in all its services using only the latest industry-standard equipment, making us a leader in the geophysical industry.
Real-time processing and results can quickly identify areas of concern (AOCs), providing valuable insight when locating underground storage tanks (USTs), digging test pits, and formulating a sampling plan.
Putting GPR to Work for Your Project
We’re honored to be a local leader for geophysical subcontractor services like ground-penetrating radar. It’s considered the most effective technology for getting real-time visuals.
It’s an ideal resource to use for construction, surveys, environmental studies, and other projects, like utility locating.
Some of the significant benefits of ground-penetrating radar include:
Safer and More Secure
Better Scan Production
There are other alternatives that can be used, but why not get the best? Call American Geophysics Inc. to be your expert when you need geophysical services like ground-penetrating radar.
The engineering and construction design team needed to core two locations for data/telecommunication and electrical feeds in the facade/false rooms that protect the elevator shafts. Even in the tight amount of available surface space, the client needed the field technician to determine the thickness of the concrete slab to core through, any structural beams or components detected; as well as mark all detected reinforcements and electrical/IT/data conduits residing in the structural concrete slab.
The client asked us to perform a geophysical concrete investigation of the laboratory roof prior to adding HVAC systems and associated piping and components. For all these proposed coring and anchoring locations on the roof, the client wanted/needed the “post-tension cables”, reinforcements, electrical conduits as well as the hollows of the (precast slab), all identified and marked out prior to performing the coring and anchoring.
The client needed to purchase and renovate this private residence/compound in Wayne, NJ. They requested a full utility mark out to locate active utilities as well as any abandoned components or potential underground storage tanks (USTs) still residing on the property.
American Geophysics stated by using both the Profoscope and concrete scanner/GPR. By doing this the field technician was able to determine the rebar size and spacing in both directions of the retention wall in question.
The client wanted to have his own IT and communications line fed to their private penthouse in New York City. In order to do so, a separate “riser” of lines needed to be fed from the basement, up approximately 50 floors.
At American Geophysics we are proud to have been able to serve the community for over a decade. This summer we had our tenth-anniversary party at a park in Boonton, NJ. Everyone on the staff had a great time and they all look forward to providing the best GPR services for years to come! Also, a special thanks to Dan for being an amazing boss and leader for the team.
An abandoned in place, decommissioned or “orphaned” underground storage tank was detected in the walkway to the home. The previous owners tried to “hide the vent line” by painting the vent line the same color as the wall, as well as, using similar piping for the railing of the staircase that matches the vent pipe.
One major thing that sets us aside from the other locating firms is that our methodology consists of three layers of investigation, whereas most firms only provide one. The other firms only use magnetometers, which solely detect magnetic/metallic presences in the subsurface.
The Philadelphia Water Department asked American Geophysics to assist with; locating active and inactive utilities, buried utility access points, detecting heating-oil USTs (underground storage tanks), as well as investigating approximately 25 proposed boring locations for contamination testing.
A client called us asking if we could help them locate a lost water well in Cape May, New Jersey. American Geophysics was able to use the GPR 250 to locate the lost water well, as well as its non-conductive piping.
Our client at a private residence in the Rittenhouse Section of Center City, Philadelphia needed to have “radiant heating coils” of non-conductive materials oriented as part of an overbuild. The project’s goal was to expand the width of the staircase.
For this project, a septic tank, and leach field needed to be investigated and oriented at a private marina, in Atlantic County, NJ. The equipment used for this project was the GPR 250 MHz, The RD8000 pipe and cable locator in conjunction with the Jameson Duct Rodder.
Projects that include non-conductive materials usually require a GPR survey in order to orient the components. For this specific project in Colts Neck, NJ the client needed the water lines coming off the well that feeds the equestrian ranch to be oriented, so we marked out the lines with blue flags.
Dan (the company’s owner), did a site audit day (or a pop-in!) to check everyone’s work across Philadelphia. Not sure how to best phrase this but maybe this can be labeled (OVERSIGHT) or (OVERSITE.) Get it?
This is a project we performed for an electric client at the PSE&G Substation in Thorofare, NJ. All the electrical conduits, and wiring systems that feed the substation from the solar field needed to be identified and located.
This project was performed in Tamaqua, PA. This was part of a Verizon site adjacent to the historic train depot. The technician needed to identify any subsurface utilities, anomalies, or data consistent with underground storage tanks (USTs).
