What is geotechnical engineering?

Geotechnical engineering is a branch of civil engineering that focuses on the behavior of earth materials like soil and rock. Geotechnical engineers investigate subsurface conditions to design foundations, retaining walls, tunnels, and other structures that interact with the ground. They assess risks related to soil stability, landslides, earthquakes, and other ground-related hazards to ensure safe and durable construction. Their work is essential in construction, mining, environmental projects, and infrastructure development.
