Soft soil exhibits more settlements, seepage, and poorer resilience to heavy long-term loads and feature void spaces ranging in size from microns to nanometers, affecting the soil’s index and engineering properties. The safe bearing capacity of foundation soil is required to design any civil engineering projects. To accomplish this, soil alterations with lime, fly ash, slag, cement, and chemical-based grouting have been employed. Nanotechnology has emerged as a sustainable approach to improve soil engineering properties significantly. Nanomaterials are material particles of nanoscale dimensions. The use of nanoparticle-enhances compounds of soil mass that provide an exceptionally good position in ground alterations. This study examines the accumulation of nanochemicals to the enhancement behavior of expansive soil properties. The percentage dose employed and the type of nanomaterial used determine improvements in geotechnical properties. Influence of properties like Atterberg limits, maximum dry density; MDD, optimum moisture content; OMC, unconfined compressive strength; UCS, have been studied. Results show the maximum improvement and the effect of nanoparticles on the worth features of expansive clay. It was observed that the soil properties are significantly improved with optimal dosage, but further improvement has yet to be observed with the addition of nano chemicals beyond optimal dosage. A successful accomplishment of this technique implies that an innovative and sustainable technique could be developed to stabilize expansive clays effectively.
