Unified Soil Classification System, or USCS soil, serves as the backbone of geotechnical engineering worldwide. For instance, a SW soil might only require a simple spread footing, while a CH soil necessitates deep piles or soil replacement to mitigate settlement risk.

These laboratory procedures provide the data necessary to plot the soil on a plasticity chart. The system further divides these into well-graded, poorly graded, and gap-graded categories based on the distribution of various grain sizes.
Organic Soils and Special Categories Identifying Problematic Materials Not all soils fit neatly into the coarse or fine categories. Applying USCS Knowledge in the Field Translating the USCS classification into real-world application dictates the entire construction strategy.

These materials are generally unsuitable for construction without extensive treatment. Understanding these classifications is essential for predicting how ground will behave under load, stress, and water exposure.
