A Type-C soil is primarily made up of which materials?

Type-C soil is characterized by its composition of coarser materials, primarily gravel, sand, and loamy sand. This classification is part of the Unified Soil Classification System (USCS) and refers to soil that is less cohesive compared to finer-grained soils. Type-C soils tend to have higher drainage capabilities and are less susceptible to deformation under load, which can be crucial when considering excavation and construction activities.

The properties of Type-C soil make it favorable for projects that require stability while allowing for adequate drainage. Understanding the composition of these soils is vital for assessing their suitability for various engineering applications, including those related to infrastructure and collection systems in wastewater management, where soil behavior significantly impacts system performance and structural integrity.
