Soil Mixing

Soil Mixing – Over 38 Years of Experience

Geo-Solutions offers state-of-the-art soil mixing techniques to remediate soil and wastes in-situ, including In-Situ Solidification/Stabilization (often referred to as ISS or S/S). Geo-Solutions utilizes two techniques of vertical auger mixing, Shallow Soil Mixing (SSM) and Deep Soil Mixing (DSM). Both SSM and DSM offer the advantage of cost savings through remediation in-place versus the high cost of offsite disposal.

Soil Mixing Applications

Excavation/Structural Support

Learn how Geo-Solutions can increase bearing capacity and reduce movement when soil mixing.

soil mixing zero-valent-iron

Zero Valent Iron

Zero valent iron aids in reducing the contaminants to less harmful constituents it is used with bentonite slurry to reduce the permeability therefore reducing the flow of contaminants.

soil mixing geotechnical


Geotechnical soil mixing is used in settlement control of soft soils supporting embankments, stabilize critical slopes, form a composite gravity structure to support excavations.
