Course Description

Earth materials, comprising soils and rocks, are the foundational elements in geotechnical engineering and construction. They form the basis of structures such as foundations, slopes, and retaining walls. Their properties vary widely depending on their mineral composition, environmental conditions, and formation processes. Understanding these materials is crucial because their classification directly impacts their engineering behavior. Soils, in particular, are three-phase systems composed of solids, water, and air. Proper knowledge ensures that materials are used safely and efficiently in structural design.
