Concrete Scanning to Locate Prior to Coring - Calgary, Alberta

Concrete Scanning to Map Rebar for Plumber Prior to Coring, Calgary, AB

Ground Penetrating Radar Systems (GPRS) of Calgary, AB was contacted by a major general contractor in town working on a project to penetrate 30 holes through concrete slabs for plumbing works. With the number of cores within a small area, it was absolutely crucial to know where the rebar were before drilling to ensure maintaining good structural integrity of the building. Within one business day, a GPRS technician was able to mobilize to the site and finished the project with the highest quality of concrete scanning to scan for all of the existing rebar and other critical targets. The 10” main slab was one month old with 8” drop panels made the job very challenging. In addition, there were 2 layers of rebar in the main slab with very dense top bars around walls, columns or beam – where were the preferred coring locations of the plumber. However, all the core was drilled successfully without hitting any rebar or objects embedded in the concrete slabs. This typical job took half a day to finish. At several places where it was not suitable to drill, GPRS expanded the scanned area to make sure the contractor had enough room to rearrange the design. All the findings were marked directly on the surface.

GPRS also provide many other types of concrete inspections such as to verify proper placement of reinforcement embedded within concrete, rebar size and slab thickness or detection etc. Ground penetrating radar technology is safe, accurate, and can mark out targets in real time. It is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to cutting or excavating.
