Ground Penetrating Radar Service (GPR)

High Tech Locating provides Ground Penetrating Radar Services (GPR) which is one of the most powerful tools for locating underground utilities.

Advantages of GPR

GPR offers the means to detect buried objects that are not detectable by other methods.

GPR Technology allows to non-invasively map subsurface objects; find metallic and nonmetallic objects; define variations in soil & rocks; and under good conditions define subsurface disturbances up to 30 feet.

GPR uses radar pulses to locate and image the sub-surfaces.

What Can Be Found with a GPR?


Almost anything! Any object that has different electrical properties other than dirt can be detected. It does not matter if the material is conductive or not. High Tech Locating uses this powerful tool for locating underground infrastructures not locatable by EM.

GPR Applications

Construction and Damage Prevention

  • Locate metallic and nonmetallic underground facilities with no a-priori information (Blind search)

  • Define areas of previous trenching

  • Plan Directional Boring with confidence

  • Find Subsurface obstacles such as rocks

  • Define utility’s depth

Environmental Site Assessment

  • Locate metallic and nonmetallic underground storage

  • Locate water table
