TheDeep Foundations Institute(DFI) is managing Deep Mixing 2015, which is the first conference in the series to take place in North America. It will focus on important advances in the materials, equipment, system design and project delivery mechanisms that have transpired since the last conference. The series of international conferences have alternated between Japan (1996, 2002 and 2009) and Sweden (1999 and 2005).
