cohesive soils

Cohesive soils are types of soil that stick together because of fine particles, mainly clay and silt, which attract water molecules. These soils have a natural ability to hold their shape and resist small forces due to their internal bonding, making them less prone to shifting or collapsing. They are often smooth, sticky, and can retain water well. Their cohesive nature is important in construction and landscaping, as they influence stability and drainage. While they can be strong when dry, they may become soft and weak when saturated with water.
