They needed to core 2 new holes in this area so we did some scanning and found them several places that were free of steel. One of the locations that were originally planned would have been right on top of a conduit this is another example of saving money but getting scanning.
This conduit was in the path of a saw cut need to link up with the drain. Our GPR was able to locate it so the saw cutting company was able to chip around the conduit and avoid the issues that cutting this 240 volt line would have caused. GPR for Slab-on-Grade applications works very well for anything ran inside the slab. However, depending on the number of voids in the gravel layer locating runs in the dirt is not always possible. In this case, the conduit in the concrete was easy to locate, but the drain pipe under the slab ran in the dirt was not visible to GPR.
