GPR for Scanning Concrete

Detect Rebar | Voids | Post Tension (PT) Cables | Conduits in Concrete Slab

Non-destructive Concrete Scanning for Safe Drilling, Coring & Cutting

  • Locate rebar, post-tension cables, metallic and non-metallic conduits embedded in concrete.
  • Create detailed scans of concrete floors, decks, columns, walls and ceilings to detect embedded objects before cutting or coring. Detect voids beneath slab-on-grade.
  • Locate and map current carrying wires using Power Cable Detector (PCD) technology.


Ground Penetrating Radar system is now widely used for scanning the interior of concrete structures. Concrete inspectors perform concrete slab inspection. When cutting and coring for renovation and repair, avoiding reinforcing bars, post-tension cables and embedded conduits is a priority. GPR can sense both metallic and non-metallic features making it a versatile imaging tool. Construction records for many buildings are not readily available and construction often differs from design resulting in GPR being the only way to confirm what is there.

3D images of Rebar in Concrete Slab


Sensors & Software enables you to see data in a 3D cube using Voxler software. Voxler is primarily a presentation and visualization tool, and while it is powerful software, it can also take some time and manipulation to create the ideal image. The images below are displayed via Voxler.
