Geophysical surveys have been conducted to profile the bedrock since the early stages of geophysics. However the accuracy of the results at shallow depth became relatively large. The development of the ground penetrating radar, over the last two decades offered an attractive method for shallow bedrock profiling. This paper outlines the methodology used and discusses the results of such surveys performed in France in various locations and geological set up in terms of efficiency, accuracy and reliability. We also give the client's economic point of view before concluding on the usefullness of the ground penetrating radar for shallow bedrock profiling.
