GROUND PENETRATING RADAR

High Resolution Concrete ImagingWorking in concrete poses hidden dangers. Knowing the precise location of rebar, post tension cables and embedded utilities is critical for operator and public safety. It also ensures structural integrity. Design and Construction professionals involved in concrete cutting, chipping and coring now have a safe and reliable means for working in this environment: high resolution concrete scanning using Ground Penetrating Radar (GPR).

High resolution concrete scanning GPR offers a detailed view of "what's within." This process yields real time results which are not possible with traditional radiographic (x-ray) methods. As important, using GPR is safe and does not require the evacuation of the public and other personnel.

Our system offers a quick and efficient inspection of slabs, floors, ceilings, roofs, columns, beams, decks, encasements, pylons, balconies, bridges, tunnels and more. We can identify metallic and non-metallic utilities, conduits, rebar, post tension cables, voids and slab thickness. A full report of your survey can be drafted to include AutoCad overlays, photos and radar profiles per ASTM 6432.
