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. Additionally, the USCS includes special classifications for materials like peat, fill, and volcanic soils, which require specific engineering considerations due to their unique origins and vulnerabilities.

Engineers use this information to select appropriate foundation types and earth retention systems. This standardized framework allows engineers to categorize soil and rock based on physical properties and grain size distribution.
The Role of Soil Testing Determining the USCS designation begins with a standard sieve analysis for coarse soils and a hydrometer test for fine soils. Understanding the drainage characteristics is also vital; coarse soils drain quickly, while fine soils may require dewatering or vertical drains.

These materials are generally unsuitable for construction without extensive treatment. Organic soils, classified as "OL," contain significant amounts of decomposed plant material and behave like soft, weak sponges.
