Cohesive Soil

Cohesive soil is a type of soil that sticks together tightly because of the clay and fine particles it contains. These soils have particles small enough to bond through surface tension, giving them strength and stability. Examples include clay and silt. They tend to retain water well and can be easily molded when wet, but may become weak or unstable when dry or overly wet. Cohesive soils are important in construction and engineering, as they influence foundation design and stability. Their moisture content and properties need careful consideration to ensure safe and effective building practices.
