This GPR Concrete Scanning job was for two cores in close proximity. The spots were marked out in orange. After scanning the hole was relocated a few inches to the left and the conduit was avoided. Always call before you dig and scan before you core.

On this GPR concrete scanning job, we found an unusual pattern in this elevated slab. They used metal pan and left a trench unfilled with concrete. This trench had a metal plate above and below it to create a walkerduct like system. We do not encounter this style of construction too often on GPR concrete scanning jobs.

In many cases, a hole needs to be cored inside a wall. In these cases, We will remove the wall track in one location and scan both sides of the wall. Then through the section removed. In this example, we found that the beam stopped just at the edge of the wall, and no steel was running parallel inside the wall. We did locate a run of electrical conduits that ran right through the third section of the wall. This was also the main location that was set to be cored with 4 cores. They just relocated the cores to the second and fourth sections and were able to avoid the electrical conduits all together. This was billed as 3 scans and came out to be about 1/15 of the price of hitting the conduits. In the long run, it is always cheaper to scan.
