Geotechnical Investigation

Overview

Geotechnical investigation is a meticulous process that involves studying the physical properties of soil, rock, and groundwater at a specific location. Geologists, engineers, and technicians collect and analyse data from field and laboratory tests. This information informs decisions related to foundation types, land use, and repair methods for natural hazards. Ultimately, geotechnical investigation enhances the safety, efficiency, and sustainability of engineering structures, including bridges, dams, railways, Highways, tunnels, pipelines, and buildings etc.
