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.
This was a GPR concrete scanning job we did at 2525 Desales Ave, Chattanooga.
It is a very clear example of why you scan. On the image to the left, the core would have been 1/4 - 1/2 inch into an electrical conduit. GPR concrete scanning will save you time, money, and headaches.
