What Exactly is a Geotechnical Investigation?

Geotechnical investigations study the physical and chemical properties of soil and rock to identify potential construction problems and evaluate distress to earthworks and structures caused by weakness or failure of subsurface materials. These investigations are essential for architects and structural engineers to recommend design criteria for the construction and design approach for new and existing projects.
