One key application for Radar is
locating pipes and cables. Radar works when cable locators don't.
Radar will (usually) see all the objects, whether metallic or
non-metallic
This is what Radar sees (as a cross section)
The pipes and cables show up as parabolas on the section
This image shows the area across the pavement adjacent to a road.
These images give depth and position of each service, and it's
depth.
Its possible to see PVC pipes, though the parabola
colours are usually less intense
This is
an example of "other " things you can do with GPR.
The
wider diffractions are air filled channels in a concrete beam, the
smaller diffractions are rebar in the concrete

This is a "3D" version of
the image above. The left hand part of the image shows the floor
slabs. The Right hand side is a poured concrete slab. The
project was to explain why the floor slab was settling. This showed
that the construction in the two areas was quite different and this
explained the reason for the differential settlement
