Babak Hamidi, Hamid Nikraz and Serge Varaksin


Nowadays various ground improvement techniques by impact are widely practiced as technical and economical solutions however each technique has its own use and range of application. It has come to the attention of the authors that the name of one of the techniques; i.e. Dynamic Compaction is being used generically in lieu of the proper names of the other methods. This article will review Dynamic Compaction and shall compare it with two other impact techniques; i.e. Rapid Impact Compaction and Impact Roller Compaction. As a conclusion the readers are advised to use the correct terminology to avoid misunderstanding and confusion in projects and results.
