Reclamation on a landfill area poses many uncertainties due to the inherent heterogeneity especially if the landfill had not been controlled properly. This paper describes a case study on the treatment of landfill using dynamic compaction technique for a reclamation work. Prior to the dynamic compaction work, a trial dynamic compaction was performed at an area of about 30m by 30m The changes or improvement of the engineering properties of landfill was assessed based on the results obtained from Standard Penetration Tests and Pressuremeter Tests carried out before and after the trial. Ground vibration monitoring was also carried out during the trial dynamic compaction test. From the results of monitoring, the induced ground vibration and the attenuation of particle velocity with distance were established.
