GPR Scanning FAQ
1. What is GPR scanning used for?
GPR scanning is used to detect and map subsurface features such as rebar, utilities, and voids in concrete, soil, and other materials. It’s widely used in construction, infrastructure, and historical preservation projects.
2. How accurate is GPR scanning?
GPR scanning provides highly accurate data, with results depending on the material being scanned and the equipment used. In general, GPR can detect features to within a few centimeters of their actual location.
3. Is GPR scanning safe?
Yes, GPR scanning is completely safe. It’s a non-invasive, non-destructive method that uses electromagnetic waves to gather data, making it safe for use in a variety of environments.
4. Can GPR detect voids?
Yes, GPR is highly effective at detecting subsurface voids in materials like soil and concrete. This makes it essential for assessing the structural integrity of roads, bridges, and buildings.
5. How deep can GPR scan?
The depth of GPR scanning depends on the material being scanned. In concrete, GPR can typically scan up to 1 meter deep, while in soil, depths of up to 3 meters or more can be achieved.
6. How long does a GPR scan take?
The depth of GPR scanning depends on the material being scanned. In concrete, GPR can typically scan up to 1 meter deep, while in soil, depths of up to 3 meters or more can be achieved.
