In the field of geotechnical investigations, we perform in-depth subsurface analyses through both indirect and direct investigation methods. Among the indirect methods, we employ advanced techniques such as MASW (Multichannel Analysis of Surface Waves), seismic tomography, and GPR surveys—essential tools for obtaining a detailed mapping of soil characteristics without invasive interventions. At the same time, we carry out direct investigations, including Standard Penetration Tests (SPT), which are crucial for assessing soil strength and load-bearing capacity.
