Ground Penetrating Radar

We use the latest ground penetrating technology to provide critical information on utilities, materials, and other potential obstructions within, or under existing structures. Fast and reliable, GPR’s provide data in both two and three dimensions without delivering any radiation. All of our equipment is registered and meets all standard FCC regulations.

Utilizing GPR reduces risk and cost, and promotes a safe work environment by providing non-destructive testing for locating materials (such materials commonly include concrete, plastic, metal, and steel, although our equipment can be used in a variety of other applications). Our client base includes hospitals, universities, surveyors, engineers, homeowners, contractors, environmental firms, and excavators

GPR systems have wide applications, such as locating underground utility lines, conducting groundwater studies or forensic research and surveying land for construction purposes.

Utilizing GPR reduces risk and cost, and promotes a safe work environment by providing non-destructive testing for locating various materials.

Our client base includes:

  • Hospitals
  • Universities
  • Surveyors
  • Engineers
  • Homeowners
  • Contactors
  • Environmental Firms
  • Excavators


Subsurface Utility Exploration (SUE)

We have the most sophisticated, state of the art equipment to find and map underground utilities. The US Department of Transportation and the American Society of Civil Engineers refer to this service as “Subsurface Utility Exploration.”

The US Department of Transportation reported tremendous savings in their case studies when obtaining subsurface utility surveys on their highway projects.

Joyner Keeny can provide you with service in accordance to the American Society of Civil Engineers standard 38-02 for Class A, Class B, Class C, and Class D surveys.

Using the Vacmaster 4000, Joyner Keeny is able, in a non-destructive manner, to uncover, photograph and obtain elevations, type and size of the utility. The Vacmaster 4000 has been used for years and has been proven to be a safe method to uncover utilities while producing minimum impact to existing roads, highways and shoulders. Once the Vacmaster is in place a two-person crew can dig a hole 6 feet deep in less than 20 minutes in average soils.
