This appears to be topic of the year around the world. We have completed a project assessing technologies for this application in both Europe and the Middle East. Some of the techniques you have already had replies from. If this is soil/air interface attack as a number of other people have experienced there are a number of techniques that do work without excavation.
The problem is not usually just one of inspection but also speed of inspection as highway lanes need to be closed and also varying geometries of lamp posts round, tapered, hexagonal.
The most effectibve method we have found which matches detection and assessment without excavation, along with data recording for verification (insurance audit considerations) and fast speed is Guided Wave Ultrasonics from GUL.
If you email me an address I can send you a copy of extracts from a study report.
