What Future for Jet Grouting? A European Perspective

The paper merges the viewpoints of producers and researchers, illustrating the considerable potential offered by the latest technological innovations in jet grouting applications, associated to the most reliable analytical and numerical design methods. An overview of the European state of the art in terms of design and execution is presented, to show that the unavoidable defects of jet grouted structures may be taken into account to assess the structural performance and establish the tolerances for execution needed to properly manage uncertainty and reduce risks. It is argued that if such an approach will be fully considered both from the technical community and from the different standard codes (as it is going to happen in Europe with the new version of Eurocode 7), a flourishing future is in front of jet grouting, with an ever increasing ground improvement market share.
