This paper shows partial results of geophysical investigations carried out in the border of São Paulo Sedimentary Basin, within the São Paulo University campus. The main objective of this research is characterizing the sediments and the top of basement rocks using the GPR - Ground Penetrating Radar and Resistivity Methods. The geophysical profiles were carried out along the same line in order to compare results obtained from these methodologies. One GPR profile (216m) was acquired employing 50MHz antennas and one resistivity profile with dipole length of 20m. Besides two verticals electrical soundings (VES) measurements were done on the same line. The analysis of GPR profile permitted to identify the bottom boundary the soil and one coarse sand layer. The result was supported by borehole information. The electrical profile identified one conductivity anomaly zone between 80 and 110m, related probably with a shear zone.
