GPRS was contacted by an environmental firm to locate any potential underground storage tanks (USTs) dating all the way back to the early ‘20s prior to soil sampling. Due to either poor record-keeping or loss of records altogether, there was no documentation to support that there were any USTs present.
After further investigation with GPR, we were able to locate a UST and provide documentation of our findings to the environmental firm. Now they can safely test the soil for harmful chemicals without hitting utilities…or even worse, USTs!
Did you know that there are an estimated 21,150 underground storage tanks (USTs) within Chicago’s city limits alone! That does not include the many unknown or unregistered USTs there may be.
Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.
“Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less.” (gprsinc.com)
GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.
Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.
