What happens to soil when it is classified as Type C?

Soil classified as Type C is defined as non-cohesive and weak, meaning it lacks the binding forces that hold particles together compared to cohesive soils like clay. Type C soils typically include sand, gravel, or other materials that do not easily stick together. This classification indicates a level of instability when excavating or working around such soils, requiring specific safety measures to prevent collapses during construction activities. Understanding the properties of Type C soil is crucial for properly assessing risks and implementing effective protective systems on construction sites, emphasizing the importance of recognizing soil types in occupational safety and health standards within the construction industry.
