Ground improvement using the vibro-stone column technique

The Vibro Stone Column technique is one of the most widely-used ground improvement processes in the world, although its potential for improving Irish sites has yet to be fully exploited. Historically the system has been used to densify loose granular soils, but over the past 35 years, the system has been used increasingly to reinforce soft cohesive soils and mixed fills. This paper will describe the technique, applicable soil types, settlement and bearing capacity calculations, recent research areas and an Irish case study.
