Soil Mixing – Over 40 Years of Experience
Geo-Solutions offers state-of-the-art soil mixing techniques that can be used to solve geotechnical, environmental, or geoenvironmental construction needs. On environmental remediation projects, Geo-Solutions can offer numerous solutions to remediate soil and wastes in-situ, including In-Situ Solidification/Stabilization (often referred to as ISS or S/S), In Situ Chemical Oxidation (ISCO), or In Situ Chemical Reduction (ISCR). On geotechnical projects, Geo-Solutions can offer soil mixing solutions to accomplish liquefaction potential reduction, bearing capacity improvement, slope stability improvement, or methods for the installation of excavation support systems. Since most underground projects involve a geotechnical and environmental component, Geo-Solutions is well versed in the interplay between these two disciplines, often termed geoenvironmental, and has numerous soil mixing techniques suitable for solving problems in this complicated area. Soil mixing has been a cost effective solution for solving environmental and geotechnical problems for nearly 3 decades and its use continues to increase as Owners and Engineers realize the technical benefits and cost savings of soil mixing relative to other available options, e.g. excavation and disposal.
Geo-Solutions soil mixing construction solutions can be used on shallow sites (~2’ to ~20’ below grade) and deep sites (~20’ to ~100’ below grade). The terms and acronyms Shallow Soil Mixing (SSM) and Deep Soil Mixing (DSM) are often used in the industry to describe soil mixing applications at different depths. Geo-Solutions can perform soil mixing in-situ using excavator bucket mixing, rotary tool mixing, single auger mixing, multi-auger mixing, and chain (trencher) mixing. Geo-Solutions is also capable of performing soil mixing ex-situ when site needs dictate. Ex-situ mixing can be performed on open ground or in controlled volume mix containers using excavator buckets or rotary tools. Geo-Solutions owns all of the specialty equipment needed for the successful completion of soil mixing, including custom modified caisson type drill rigs on tracked chassis, custom drill rigs designed for crane mounted systems, a chain type soil mixing machine on a tracked chassis (the Geo-Trencher), rotary mixing heads, and numerous batch type, automated, and continuous mix batch plants.

Soil Mixing Applications
The acronym LDA is used by industry professionals in multiple applications. In some cases, LDA is used to refer to the practice of performing discrete excavations using an auger, possibly referred to as LDA excavation. In other cases, the term LDA is used to broadly describe soil mixing performed with large augers, possibly referred to as LDA soil mixing. Finally, the acronym can be used to refer to steam treatment performed with augers, possibly referred to as LDA treatment.
