Ground Penetrating Radar (GPR) is a geophysical locating method that uses radio waves to capture images below the surface of the ground in an innovative way. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables, or masonry. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum and detects the reflected signals from subsurface structures.

GPR can have applications in a variety of applications, including rock, soil, ice, fresh water, pavements, and structures. In the right conditions, technicians can use GPR to detect subsurface objects.

Significant applications include:

What Sets Us Apart?

At Precision Surveying & Consulting, we use ground penetrating radar (GPR) to provide accurate subsurface information during our surveys. GPR works by sending high-frequency radar waves into the ground and recording the radar signal that is reflected back.

How GPR Works

The electromagnetic energy travels through the subsurface at different speeds, depending on the material’s electrical conductivity. The travel time and the amount of energy reflected back to the antenna provide us with valuable information about the subsurface features.

Advantages of GPR Technology

Our experienced surveyors can identify changes in the ground’s conduction properties and locate buried objects, such as utilities, foundations, and buried debris. With utility locating becoming more critical, our GPR technology allows us to locate underground utilities with greater precision and efficiency.

GPR Data Collection and Analysis

Our team uses the latest GPR systems to collect and analyze data, providing our clients with comprehensive and accurate subsurface information.

The GPR system is particularly useful in moving from dry sand, where traditional survey methods may be difficult to use.
