GPRS Scans Congested Streets Before Soil Boring

An environmental firm contacted Ground Penetrating Radar Systems (GPRS) to scan a sidewalk for utilities prior to soil boring in downtown Evanston, Illinois. The client needed to to find a safe area on the sidewalk to drill and test for possible soil contaminants. While scanning the areas of concern, we were able to locate a water line that ran right through one of the original proposed drilling locations. What an expensive mess that would have been! Once this scan was finished, the contractor was then able to relocate their drilling locations accordingly.

Scan before you plan! This ensures worker safety, and it can help you save valuable time by targeting specific areas of concern. Depending on the specific needs of your project, in addition to marking the results of a scan onto your project's surface, we can also provide you with a GPS report overlaid on Google Earth, or overlay scan results onto a pre-existing CAD file.

GPRS can locate items such as reinforcing, utilities, conduit, and underground storage tanks. By having an area scanned first, costly/dangerous mistakes that can set your project behind can be avoided. Call GPRS prior to core drilling, saw cutting, trenching, soil boring, directional drilling, and anchoring, and we will help you keep your project on time, safe, and within budget.

Ground Penetrating Radar Systems often uses a conjunction of both GSSI (Geophysical Survey Systems, Inc.) Sir-4000 GPR and Radio Detection (a RD-8100 Locator) to locate utility lines. We can also can locate utilities that are in or under concrete via induction or conduction with an exposed or known surface utility line, and all of this is done in a safe, time efficient, non-destructive manner.

Also, at Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, and often within 24 hours or less.
