GPR Arkansas specializes in commercial and residential ground-penetrating radar services for Little Rock and the surrounding areas.
Ground-penetrating radar (GPR) is a non-invasive geophysical technique that uses high-frequency electromagnetic waves. This creates images of subsurface features and structures.
It works by sending a radio wave signal into the ground. It then measures the time it takes for the signal to bounce back to a receiver. Utilizing the reflection of the signal from various layers of soil or rock, researchers can generate a comprehensive image of the subsurface.
A portable GPR cart, roughly the size of a push lawnmower, features a transmitter and antenna. As the cart passes over a grid-style surveyed area, high-frequency radio waves pass into the ground. When the radio waves encounter a buried object or the boundary between materials with different permittivities, the wave is bounced back to the surface.
The GPR cart’s receiving antenna records variations in the return signal, generating a GPR survey report. Working in Little Rock and surrounding areas, our expert GPR technicians are able to analyze the report and pinpoint where disturbances, such as utility lines or voids, occur beneath the surface.
GPR can be used to find or measure a sizable number of items underground or within concrete slabs. These include:
Some of these can be especially important for safety reasons. You don’t want to accidentally cut a post-tension cable while cutting into a concrete slab. Cutting into electrical wires can also be dangerous.
