The Reports be given to the conference and the author(s). summarise best practice, based on the author’s experience, including relevant papers submitted to Deep Mixing´05, but also on recent developments, which were presented at other conferences and the geotechnical literature. The advantages and the limitations (technical, economic, traditions etc.) of deep mixing methods are described. Future needs of improve- ment with regard to the session themes are presented. Keynote Lectures by invited experts focus on specific topic, chosen by the lecturer within the scope of the technical ses- sions. Technical Papers were accepted based on submitted abstracts. A scientific committee reviewed the draft papers. Based on the main topic addressed in the respective papers, these were assigned to the most appropriate session.
