The present Summary highlights the significant contributions of the Short Courses on Deep Mixing coordinated under the guidance of J. Maertens, N. Denies and N. Huybrechts and organized within the framework of the IS-GI Brussels 2012. This Summary concentrates on the latest developments and current researches in the deep mixing method (DMM). The content of all the presentations is harmonized and structured as follows. Different execution processes are summarized or classified and their mechanisms are outlined. The recent advances related to the mechanical characterization of the soil mix material are then discussed. Various applications of the technique are illustrated with the help of case histories focusing on ground improvement (GI) works but also on structural and environmental uses of the DMM: foundations and soil reinforcement, earth/water retaining structures and cut-off walls, land levees and floodwalls, in situ remediation, etc. Finally, QA/QC procedures are briefly discussed and the importance of construction monitoring is underlined. Many references on the topic of DMM are also given in the Summary.
