Abstracts: ? Analysis and assessment of expansive soils is of almost importance while founding the structures, as these soils undergo large volumetric changes even due to small fluctuations in water content. ? The volumetric changes are very large in magnitude and they are responsible for distress of structures. The amount of damage caused by expansive soils is alarming. ? An attempt to study the geotechnical properties of the black cotton soils of Sabarkantha region especially at Modasa Town and to study the type of foundations provided, their stability, failure, possible reasons for failure, restoration work undertaken if any was made. ? Here cracks are live and 1/2” wide and 12” deep. ? Thorough understanding of engineering properties of soils are essential not only for using current methods in the design of earth structures, but also to provide a key to further progress in the field of geotechnical engineering.
