About Holes Technology

Utility Locating

The Holes Incorporated Technology Division is comprised of Utility Locating and Ground Penetrating Radar (GPR) services.  These high-tech services allow our technicians to quickly identify and mark the position and depth of both metal-based objects like rebar, conduit, and post-tension cables, and non-metal objects like gas lines, communications, sewer lines, underground storage tanks, PVC pipes and other underground structures.

Identifying the location of these types of objects are important before any project that involves digging, trenching and subterranean work. Our team will skillfully locate possible obstructions and hazards, saving your project time, money and potentially dangerous situations.

At Holes, all of our GPR Technicians have been trained and certified by the Concrete Sawing and Drilling Association (CSDA).


Utility Locating and Ground Penetrating Radar provides numerous benefits including:

  • Ability to easily inspect dense materials, floors, walls, decks, slabs and other concrete and earthen structures.
  • Accurately locate metal and non-metal objects such as rebar, post-tension cables, conduit, PVC pipes, utilities and other vital underground structures.
  • View and access targets to a depth of up to 24” deep in concrete and 4 to 6 feet deep in prepared surfaces and rugged terrain (depending on soil conditions and sea-level elevations).
  • Inspect vast areas of concrete and non-concrete surfaces in a non-destructive manner.

How It Works

Unlike X-Ray technology which requires access to both sides of an object, this complex, nondestructive technology requires access to only one side of the object making it ideal for construction site use. Also, unlike x-ray systems, Utility Locating and Ground Penetrating Radar can be performed during regular business hours and activity. Utility Locating and Ground Penetrating Radar systems provide clients with pin-point accuracy on the location of impediments and important unearthed structures.
