concrete pavementThis article aims to outline the established Ground Penetrating Radar (GPR) applications for concrete pavements that are currently under development or not yet commonly applied. GPR is a non-destructive method that detects variations in the electromagnetic properties of materials, ...

A concrete foundation and a layer of lava pebbles were revealed at 1.5 m depth; the following layer (from 1.5 to 2.3 m) is constituted of pebbles of rubble and basaltic blocks with different size; sandy clays, rehandled with small percentage of Conclusions The combined used of complementary ...
To put it simply, Ground Penetrating Radar (or GPR) shows you what is underneath the surface. It is a technique that uses electromagnetic energy signals to penetrate a variety of materials such as concrete, soil, rock, ice and pretty much any non-metallic and non- conductive media. GPR ...

Xu et al. (2006)give a synopsis and examples of the 20+ projects they have used WPR for, mainly around dams and in locks and lock chambers where they identified: places of uneven settlement (both of the dam but also foredam concrete aprons); cracking of submerged concrete aprons and stru...
Subsurface, Road and Concrete Imaging Solutions Use Ground Penetrating Radar To Reduce Risks and Costs Ground penetrating radar, or GPR, is a geophysical method that uses radar pulses to image the subsurface, or allow clients to 'see' what is underground. ...
