[ What We Do ]

[ Concrete Scanning ]

Cutting into concrete slabs without knowing what obstacles may lie beneath is a dangerous practice. Post tension cables, unmarked utility lines, and more can, when struck or cut, cause accidents that result in serious injury or even death. Using Ground-Penetrating Radar (GPR), we can see inside the concrete before you cut, allowing you to know all obstacles before you proceed with your project.

[ Utility Location / Dig Alert ]

It is always necessary to call 811 before you dig. But that doesn’t necessarily mark all utility lines. Some private utility lines might be missed. Ensure you know all of the obstacles beneath you, including fiber optic cable, gas lines, water lines, sewer lines, and more! Call us today and let us take on the stress of mapping your property, whether commercial or residential.

In the hands of professionals, Ground Penetrating Radar (GPR) is a powerful tool that can allow the user to see more than just utility lines and rebar. GPR has a variety of uses, including the location of private utility lines, unmarked graves, and even items of interest to archaeologists.
