Soil mixing is an in-situ ground improvement technique that enhances the characteristics of weak soils by mechanically mixing them with a cementitious binder. The action of mixing materials such as cement with soil causes the properties of the soil to become more like soft rock.
Slattery Drilling provides two types of soil mixing for both geotechnical and environmental applications, single column mixing and mass mixing.
Soil mixed columns may be single or overlapping quadruple columns installed for cut off walls or to improve the bearing capacity of the soil. The advantage of soil mixing is that it transforms the various different soil properties into a consistent and uniform material providing dependable properties that can be used in the design with confidence. Monitoring throughout the pile installation ensures that the soils have been mixed with the correct binder quantities and sufficient agitation has achieved homogeneous mixing.
