Frequently Asked Questions

Ground-penetrating radar is a geophysical method that uses radar pulses to image the subsurface. 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 of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks.

• Real time detection of subsurface anomalies,utilities, structural reinforcement.

• Detect subsurface trenching and soil disturbances

• Can detect concrete rebar deterioration

• Can detect grouted / ungrouted CMU cells

• Can detect shallow and deep targets in concrete and below grade

• Does not emit any type of lethal radiation like X-ray.

• Less costs than X-ray

• No film or digital processing needed like X-ray

• Can detect concrete thickness and voids.

• Non invasive

• Self contained quiet operation

• Can cover vast areas

• Can detect geological layers and some non metallic anomalies

• Can detect subsurface without access to both sides
