Expansive soils are problematic in nature by virtue of their innate capacity to undergo volume changes when there are changes in moisture regime. These soils swell when they absorb water and shrink when water evaporates from them. So, lightly loaded civil engineering structures founded in these soils are subjected to alternate swelling and shrinkage in rainy and summer seasons. As a result, they experience unsightly cracking. The structural members that get affected are flooring, walls, columns, grade beams, etc. The types of damage are disruption or disintegration of flooring, tensile cracks...
