Geotechnical Investigations

Geophysical methods can reliably investigate geotechnical properties of in-situ soil and bedrock as well as engineered structures such as dams. Structural information includes the depth to bedrock and phreatic water level, soil strength and stiffness, fractures and underground voids. Detailed insight can also be obtained on foundation features, water percolation and liquefaction potential.

Geophysical solutions employed by SGC to conduct these investigations include Multi-channel Analysis of Surface Waves (MASW), Seismic Refraction surveys, Electrical Resistivity Imaging (ERI), Electromagnetic Induction (EMI) and Ground Penetrating Radar (GPR).
