what is geotechnical engineering all about | Complete information

Geotechnical engineering all about understanding and working with the Earth’s materials, like soil and rocks. It’s like being a detective, trying to figure out what lies beneath the ground and how it affects buildings, roads, and other structures we build. Geotechnical engineers study the properties of soil and rock to determine if they can support the weight of a building or if they might shift or settle over time. They also help design foundations, slopes, and other structures to make sure they’re safe and stable. So basically, geotechnical engineering is about making sure the ground beneath our feet is strong and reliable for the structures we build on it.
