Can Ground Penetrating Radar determine the difference between rebar and electrical conduit?
In most cases, yes we can determine the difference. It is true that rebar and electrical conduits have nearly the same type reaction on the data screen. We are able to differentiate by determining the rebar pattern (spacing and elevation) and when the pattern is broken, in all likelihood, it would be a conduit breaking the pattern. We have an extremely high success rate in applications where we are asked to find electrical conduits in supported slabs or in slabs-on-grade prior to saw cutting or core drilling.
