Although the CTE facilitates the application of geophysical prospecting techniques as complementary information to mechanical borings for the geotechnical characterization of the ground, its use in building is little widespread, making appropriate studies that analyze the benefits of its use. This article presents a comparative analysis of the results obtained using an experimental campaign with geophysical and traditional prospecting techniques. The methodology used has consisted in the characterization of a ground by seismic refraction tomography with microtremor analysis and mechanical borings, comparing them with the data obtained during the subsequent implementation of a foundation underpinning on the same site.The results have allowed to evaluate the limitations of each method and advantages of their combination.In conclusion, the application of geophysical prospecting techniques complementary to mechanical borings has contributed to a better geotechnical characterization of the ground, improving the planning and estimation of building project costs.
