What is it about?
Small GPR devices are cheap and easy to use for the detection of metal inside concrete structures. In this paper, one of this devices is used to detect internal cracks produced during desiccation processes in clayey soils. This detection is important because these internal cracks were not studied before.

Why is it important?
This research is important because the origin and the development of cracks in clayey soils subjected to desiccation are not clear. It is necessary to understand the process in details in order to discover the physics behind the process. Once the process is understood, numerical models can be proposed to study the initiation and propagation on cracks.
