βοΈ Happy Monday from Safe2Core! βοΈ
Let's kick off the week with a quick construction question:
π Q: How deep can Ground-Penetrating Radar (GPR) scans go?
π‘ A: The depth of a GPR scan depends on antenna frequency, site conditions, and the material being scanned.
β
In concrete, GPR typically penetrates up to 18β24 inches for locating rebar, conduits, and post-tension cables.
β
In favorable soil conditions, lower-frequency antennas can detect utilities and subsurface features at depths of 10β15 feet or more.
β
Higher-resolution scans provide greater detail but generally at shallower depths.
Every project is different, which is why proper equipment and experienced interpretation matter.
Before you cut, core, drill, or dig, make sure you know what's below the surface.
