Mitigating Seismic Hazards with Deep Soil Mixing
Deep soil mixing (DSM) is an increasingly popular ground improvement technique to provide foundation support for structures and to mitigate seismic hazards. DSM is a powerful method thanks to its ability to treat nearly all soils and its flexibility to form different geometric shapes. This presentation will provide an overview of the DSM construction method and typical QA/QC measures. Case histories will be used to illustrate the design and construction of DSM to mitigate seismic hazards including surface fault rupture, liquefaction and lateral spreading. Attendees will gain a deeper understanding of how DSM can be employed to solve challenging earthquake engineering problems.

Every day, people around the world live, work and play on ground prepared by Keller. Used alone or in combination, our techniques solve a wide range of geotechnical challenges across the entire construction sector - from industrial and commercial to housing, infrastructure and environmental projects.

What about the durability of deep soil mixing?
Like concrete, portland cement in soilcrete continues to hydrate and cure over time to pick up strength. We typically use sulfate resistant (Type II/V) cement. We have not experienced any problems with degradation over time.
How and why is this used in FL soils and also with its crushable limestone “bedrock”?
Keller has performed deep soil mixing extensively in Florida. Even with crushable calcareous sands or limestone, we can achieve target soilcrete design strengths that are necessary to meet project requirements.
