: Utilizing chemical stabilization (lime or cement injection) to reduce the soil's plasticity index [15, 24]. Summary of Foundation Options Foundation Type Application Key Advantage Drilled Piers Heavy structures Reaches stable soil/bedrock [28]. Stiffened Mat Light structures High rigidity resists cracking [11, 21]. Granular Cushions Light/Moderate loads Reduces swelling potential directly under footings [2, 21]. Soil Replacement Sites with thin expansive layers Replaces active clay with stable material [6].

F.H. Chen's seminal work, , is the definitive engineering guide for building on "shrink-swell" clays. These soils are notorious for their high plasticity—absorbing water to expand and drying out to contract—which can exert enough pressure to crack foundations or heave entire structures. Chen's seminal work, , is the definitive engineering
