Geotechnical

Founded purely as a geotechnical engineering firm in 1970, GEI has been an industry leader in the application of geotechnical principals to achieve safe, economical and practical projects. We are highly experienced investigating, evaluating and navigating the risk and uncertainty of the underground to overcome challenges presented to both routine and complex projects by variable soil, rock, and groundwater conditions, fast-track schedules, and sensitive adjacent buildings and infrastructure. Focusing on foundations, excavation support systems, tunnels and lab testing, GEI works closely with structural engineers, architects, developers, owners and contractors to reduce risks and uncertainties in underground construction.
