We use the latest ground penetrating technology to provide critical information on utilities, materials, and other potential obstructions within existing structures or underground.  Fast and reliable, GPRS provides both two- and three-dimensional images of the scanned areas without delivering any radiation.  All of our equipment is registered and meets all standard
FCC regulations.

Utilizing GPR reduces risk and cost, promotes a safe work environment, and provides non-destructive testing by locating materials such as concrete, plastic, metal, steel, rock, soil, ice, and pavement. Our client base includes hospitals, universities, surveyors, engineers, homeowners, contractors, environmentalists, and excavators.

“This project involved a foreclosed private residence on a 2.5 acre rural site which was suspected of being a small gas station from the late 1920’s to early 1940’s.  The project site was located in Montgomery, Michigan, which is in the south central portion of the Lower Peninsula near the Indiana line.  Arch Environmental Group, Inc. was retained by Fannie Mae through the local REO repair coordinator to conduct an environmental assessment and complete other services at this location.  We utilized GPRS to search for any potential abandoned UST’s and piping, and to locate septic tank, drains, and other nearby underground utilities.   GPRS located the precise areas of various suspect items, which we excavated as part of our follow-on work in completing the environmental assessment.  As noted below, by having the septic tank and connecting drains precisely located by GPRS, we were able to save valuable project time in getting the tank pumped out and assessing the downstream seepage pit.  “

Here are some of the highlights from this home foreclosure subsurface investigation, along with photographs:

1.GPRS flagged “potential buried suitcase”.  We hand excavated and found duffel bag with pet remains.	2.GPRS flagged “potential small tank/curved metal surface”.  We used mini-excavator and found a nice flanged steel tank which was recycled. Luckily this contained no contamination.
3. GPRS flagged “potential debris, possibly rusted drum”.  We used mini-excavator and found debris, including rusted barrel, old petroleum hoses from old gas station, and various other pieces of ancient household trash (very old bottles, metal parts, minor residues, shoe soles, animal bones, etc.).  We excavated and disposed of all items. 4.GPRS flagged “septic tank and connecting pipes”.  We hand dug and quickly found septic tank, saving time during the pump out process.
Along with all these items that were located a spot check of the other flagged items (drains, cable lines, etc.) also proved accurate.  Details and photographs were provided by Peter Dahlgren, PE, CHMM Arch Environmental Group, Inc., Farmington Hills, MI visit them on the web at http://www.archenvgroup.com/
