Utility Locating

Contact For Services

Having knowledge of exactly where underground utilities and features in the subsurface are located ensures that the project can proceed effectively, efficiently and safely. 

Disrupting private utilities on a project, causing unnecessary headaches for your clients can be a nightmare, but can also be avoided. Prior to any coring, cutting, digging or drilling, It is important to have a Utility Location Survey performed to avoid any accidental shutdowns, safety hazards, or increased insurance through accidents.

Ground Penetrating Radar (GPR)

​Ground penetrating radar (GPR) offers the means to detect embedded or hidden objects within the near subsurface. This non-destructive method uses electromagnetic energy to detect reflected signals from subsurface structures. GPR can be used in a variety of media including concrete, brick, asphalt, and soil. GPR can detect objects, changes in material, as well as voids and fractures.
​
GPR uses transmitting and receiving antennas. The transmitting antenna radiates short pulses of the high-frequency (usually polarized) radio waves into the surface. When the wavelet hits an embedded object or a boundary with different dielectric constants the receiving antenna records variations in the reflected return signal.
