Ground Penetrating Radar (GPR)

Ground  Penetrating Radar (GPR) transmits pulses of high frequency radio waves into the ground to produce a cross section of the subsurface strata without drilling or excavation.  GPR is ideal for location of non-metallic pipes, underground storage tanks, and other structures. Combining this method with traditional utility designating and utility locating methods helps us locate and inform you on whatever is beneath the surface that you need to know.

Air Vacuum Excavation Test Pitting

Air excavation provides us a non-invasive and non-destruction excavation system. After we designate and locate the underground utilities, air excavation test pitting allows us to precisely determine the exact location and depth of the buried utility cable, tank or structure. The excavation is able to expose utility lines with complete safety.  The test pit is usually an 8” by 8” cut.  The air probe breaks up the soil and the vacuum system uncovers the utility.  Soil and surface cover is restored to its original condition.

Utility Locating • Utility Designating

If you are in the initial design or civil engineering phase of your project we will locate underground utilities using electromagnetic, geophysical and sonic methods to locate underground utilities and structures.
