The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol.

WebbGrain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.

WebbSoil is classified so it can be more easily understood and utilized in the planning stage. Soils are classified by: SILT (0.005mm than 0.075mm) and CLAY (0.075mm to 0.075mm to the negative tenth degree) In addition to soil classification, soils may also be identified by whether or not they are ‘confined’.
