 · Collapsible soils are generally dry low density silty soils with high void space or air gaps between the soil grains where the soil particle binding agents are highly sensitive to water. These micro-pores can sometimes be seen by the naked eye. When exposed to and weakened by water the binding agents break soften or dissolve such that the

Expansive Clayan overview ScienceDirect Topics

Expansive soil or clay is considered to be one of the more problematic soils and it causes damage to various civil engineering structures because of its swelling and shrinking potential when it comes into contact with water. Expansive soils behave differently from other normal soils due to their tendency to swell and shrink.
