What is Ground Penetrating Radar (GPR)?
Ground Penetrating Radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface. It allows us to detect and identify underground utilities, structures, and other objects without any digging. This technology is essential for safe and efficient excavation, drilling, and construction.
Our GPR Services
- Utility Locating: Accurately locate electric, gas, water, and communication lines before you dig.
- Subsurface Anomaly Detection: Identify voids, buried debris, and other potential hazards hidden underground.
- Concrete Scanning: Locate rebar, conduits, and post-tension cables within concrete structures.
- Geotechnical Surveys: Assist in geotechnical investigations by identifying soil layers and bedrock depth.
See Before You Dig
With GPR, we take the guesswork out of excavation. By creating a detailed map of the subsurface, we help you avoid costly and dangerous utility strikes, ensuring your project proceeds safely and on schedule. It’s an indispensable tool for modern construction and site development.\
Frequently Asked Questions
What is Ground Penetrating Radar (GPR)?
GPR is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive and non-destructive technique that allows us to see what’s beneath the ground without any digging.
How deep can GPR see?
The depth of penetration depends on the material being surveyed and the frequency of the antenna being used. In ideal conditions, like sandy soils, we can see as deep as 30 feet. In less ideal conditions, like clay or wet soils, the depth may be limited to a few feet.
What can you locate with GPR?
GPR can be used to locate a variety of metallic and non-metallic objects, including utilities (pipes, cables), underground storage tanks (USTs), rebar and post-tension cables in concrete, voids, and even unmarked graves.
Is GPR safe?
Yes, GPR is extremely safe. The radio waves used are of very low power, comparable to that of a cell phone, and pose no risk to people or the environment.
