GPR Scanning

When job site conditions require a reliable, non-destructive means to locate targets within concrete structures prior to drilling, cutting or coring, Ground Penetrating Radar Scanning is the tool of choice.

Field-proven accuracy for locating rebar, post-tension cables and conduits makes GPR scanning invaluable in these situations.

GPR works by sending a tiny pulse of energy into a material and recording the strength and the time required for the return of any reflected signal. A series of pulses over a single area make up what is called a scan.

Different materials reflect signals at different speeds and rates, when viewed by Concrete Cutting & Breaking Cos. trained operators most metallic object or voids are identifiable.

Fieldwork typically requires one operator. Imaging results are generated on-site for immediate mark out
of targets in the selected area. The inspection can be performed on one side of the slab, which permits
slab-on-grade scanning. Some common applications of GPR include, but are not limited to:

  • Locating reinforcing bars
  • Locating post-tension cables
  • Locating metallic and non-metallic conduits
  • Detecting voids beneath slab-on-grade
  • Slab thickness and cover depth to targets
