ABSTRACT It is strange paradox that most of the better land areas have been utilized for building simple and conventional structures on them. More or less the same situation exists in all urban areas and mega cities. Now, that major taller and more sensitive structure are required to be built for the systematic growth of these urban centers. The land available is inferior, weak and apparently unsuitable for placing such big and massive structures. There is another point to be considered for the safety of these structures and the people living in them; during the seismic activities. The situation leads to take recourse to methods and technique by which the condition of the ground or land can be improved and made suitable for the placement of planned structure on them. Weaker grounds or lands are those which are recognized as bad land swamps, marshy areas, reclaimed land, huge backfilled areas and permafrost areas. Since the characteristics of the weaker land surface are variable in nature the technique and methods of improvement to be adopted would also be different. But these have to be already applied methods and techniques having been evolved after due research and field practices. In Civil Engineering constructions sometimes problems arise due to the site of the construction not being firm enough to support the structure proposed on it. The problem becomes more acute when there is no possibility of the availability of an alternative location with better ground condition. Field engineers have to devise ways and means to accomplish the task of meeting the challenge of the site either by choosing to provide a costly, but, safe foundation design to the proposed superstructure or by improving the ground conditions to make it suitable to support the structure safely and yet the cost effectiveness of the project is maintained. Several methods of ground improvement are available. The suitability of different methods depends upon the type of the soil, drainage conditions, relative density, degree of expansiveness etc. ...
