The problems of expansive behavior of soil are as follows (N.B.O. 1962). a. Expansive soils have high plasticity and compressible when they are saturated. b. These types of soil have high strength in dry state, becomes soft after saturation. Filling up water into Most of the expansive soils need stabilizations because expansive soils swell when it comes in contact with water and this is the major reason of failure of expansive soil strata.

Likewise, when expansive soils lose moisture, they begin to shrink. Expansive soils have the ability to drastically swell based on the amount of expansive minerals and moisture that is present in the soil. Expansive soils generally contain some form of clay mineral that is able to absorb water and swell when wet then shrink when dry. Expansive or swelling soil is a highly plastic soil that normally contains montmorillonite and other active clay minerals. Expansive soil is a commonly identified problem which has made scientists
Soils that exhibit changes in volume with changing moisture content are called expansive soils.
