A 70 km long section of a highway was investigated using Ground Penetrating Radar to detect possible cavities under the concrete pavement. The highway was built more than 20 years ago and the available documentation about the construction was not detailed enough..

Increasing loads of traffic on roads, bridges, and runways leads to degradation of concrete pavements. Repair is both time consuming and expensive.

A project to locate areas of sand inclusions in concrete at a residential housing complex in California was recently completed by a Sensors & Software Conquest client.

Ground penetrating radar (GPR) plays an important role in evaluating lateritic nickel deposits.

Lateritic nickel forms in areas of deep weathering in tropical regions. Initially, GPR was thought to be of limited potential since these weathered areas can have high electrical conductivity. Surprisingly in situations where the watertable is deep, depths of 30 to 40 m of exploration have been achieved.
