In this paper main emphasis is put on methods for improvement of soft ground with the use of vibro compaction methods, Vacuum consolidation, Soil nailing, Grouting methods and dewatering methods. Vibro-compaction increases the density of the soil by using powerful depth vibrators. Vacuum consolidation is used for improving soft soils by using a vacuum pump. Preloading method is used to remove pore water over time. Vibro replacement stone columns improve the bearing capacity of soil whereas Vibro displacement method displaces the soil. Many ground improvement techniques are available to suit the particular needs of soil type, structure type and performance criteria. These techniques offer cost effective solutions, whilst reducing construction period considerably. Furthermore, these techniques also offer environmental friendly systems, which is important for urban areas.
