The Deep Foundations Institute (DFI) has released a new publication, “Guidelines for Soil Mixing.” The publication provides an overview of the state of practice of deep mixing methods (DMM) in North America, as well as a guide specification for deep mixing work.
The 80-page document focuses on constructability and feasibility considerations for deep mixing. It addresses applications including: earth retention; liquefaction mitigation; groundwater seepage control and containment isolation; bearing capacity improvement; deep foundations; mass stabilization and contamination containment; embankment, levee and dam strengthening and stabilization; and casing replacement. The document was created to provide a basic introduction to wet and dry DMM to enhance its adoption and application in North America.
“Guidelines for Soil Mixing” is available on the publications page on the DFI websit. The cost is $30 for DFI members and $50 for nonmembers. Purchase of the publication includes a PDF of the full guide and an editable Word document of the Guide Specification.
The DFI is an international association of contractors, engineers, academics and suppliers in the deep foundations industry with more than 3,300 members worldwide. For more information about the Deep Foundations Institute, visit www.dfi.org.
