Ground Improvement by using Grouting Technique- an Overview Study

Abstract

Recent past years have faced rapid growth of population, fast urbanization and more development of infrastructures like buildings, highways , railways and other structures, resulted in reduction of availability of good quality of land. Therefore engineers have no choice left except to use soft and weak soils around by improving their strength by means of suitable modern ground improvement techniques for construction activities. At present the available ground improvement techniques such as replacement of soil, vertical drains, stone columns, compaction, dynamic compaction, soil reinforcement, piers, in-situ densification, pre-loadings, grouting and stabilization using admixtures. The aim of these techniques is to increase the bearing capacity of soil and reduce the settlement. The soil grouting is most important procedure for the ground improvement. In soil grouting many method such as pressure grouting, jet grouting, chemical grouting, cement grouting etc. Pressure grouting technology has been widely adopted in ground improvement and soil stabilization.
