Deep Soil Mixing - Advanced GeoSolutions, Inc.

Deep Soil Mixing (DSM) is a ground improvement technique through blending a hardening agent (usually cement grout) with the native soils, in situ. The process improves the strength and stiffness of the soil to increase bearing capacity, decrease settlement, and mitigate seismic issues. Also used to form walls for excavation support, erosion control, or contamination barriers.

Soil Remediation Using Mixing and Handling

Soil remediation using mixing and handling is a process of physically blending and mixing soil, contaminant and reagent using specialized equipment to facilitate treatment. This practice can be efficiently performed in-place within the top 10-12 feet of soil (above the water table) or, alternatively, the soil can be excavated, moved and mixed in another location as needed.
