Geo-Technical Engineers all over the world fare enormous problems, when the soils founding those structures are expansive in nature. Depending upon the use of soft clay soils as foundation support or construction materials. Their properties need careful study to estimate their potential for damages based on volume changes, with reference to imposed structural loads and tolerance of structure for maximum settlement Among several techniques adopted to overcome the prob-lems, lime stabilization gained prominence during past few decades due to its abundance and adaptability The main objective of this project is to improvement of soil property of soft clay soil without using any admixtures i.e., by using CNS (Cohesive NON- Swelling soils). An attempt has been made to use these materials for improving the swell, plastics compaction, and strength and penetration characteristics of problematic clay soil which also prove environment friendly.
