f Some applications of GPR to the geotechnical studies

GPR is one of the geophysical tools which provides fullest information about the first meters of ground. For this reason, the use of this geophysical technique for geotechnical studies is getting more frequent. In this document are shown two cases of GPR use in geotechnical studies. The first one has been carried out in Barajas-Madrid Airport in order to detect voids and alterations near a service gallery of the airport. The second one has been carried out in Arguedas cross-street (Spain) in order to study the ground near the water pipes where many water leakages had been produced in a gypsum and limestone ground.
