Geotechnical Engineering uses the disciplines of soil and rock mechanics to investigate subsurface and geologic conditions. These investigations play a key role in all civil engineering and construction projects that involve construction on the surface or within the ground including foundations, earth structures and pavement subgrades. GSG’s geotechnical engineering experts allows us to reduce ambiguity by offering innovative, strategic, and cost-effective solutions to the underground challenges which often arise during design and construction. Our team of geotechnical engineers, engineering technicians, and geologists provide geotechnical analysis, design, and construction services to architects, structural engineers, developers, civil designers/engineers, and contractors. We complete comprehensive investigation programs and provide sound geotechnical engineering recommendations based on theoretical and practical analysis of data.
