Drill-Tech - Cutter Soil Mixing Technologies (CSM)
Drill Tech is continually at the forefront of the geotechnical construction industry, utilizing innovative new technologies for earth retention and ground treatment. Over the past 15 years, Drill Tech has expended a tremendous amount of time and effort to further develop the use of the cutter soil mix method for earth retention and ground treatment needs.
A continuous wall is formed by overlapping a series of rectangular soil mix panels. The panels are typically reinforced with steel beams for structural purposes. CSM is mainly used for stabilizing soft or loose soils. However, the cutter technology extends the applicability of the method to much harder strata when compared to other methods of soil mixing.
Typically, every second shaft is reinforced with a steel beam or reinforcing cage and the intermediate shafts are filled with lean concrete. When secant piles are used to shore a circular shaft excavation, vertical steel reinforcement is typically unnecessary, because the secant piles form a concrete compression ring.
CSM is used as a ground improvement method to create homogeneous foundation support and increased bearing capacity, and to mitigate liquefiable soils. CSM can also be used as a barrier to contain the migration of underground contaminants.
- Native soils are used as the construction material
- Can be used in very dense soils and weathered bedrock
- Minimal generation of spoils
- No vibrations and little noise during construction
- Cut-off walls
- Excavation shoring in saturated and loose soil conditions
- Shaft construction
- Foundation support
- Liquefaction mitigation
