As a premier contractor specializing in soil mixing, Schnabel emphasizes the importance of careful and correct soil mixing as the foundation of robust earth-retention solutions. The methodical process yields a sturdy soilcrete mixture characterized by its increased strength and lower permeability.
In the realm of earth-retaining structure construction, soil mixing plays a vital role especially when groundwater cutoff is required. Schnabel commonly establishes a continuous groundwater cutoff wall by drilling overlapping soilcrete columns.
To further fortify the soilcrete, steel piles are typically embedded while the mixture is still damp. The resultant strength of the treated soil allows it to bridge the intervals between the piles. Additionally, the permeability reduction achieved by a soil mix walls enables excavation to occur under mostly arid circumstances with minimal reduction in the external water table levels.
The scope of soil mixing extends beyond these applications. It can also be used to form an impervious barrier beneath the ground surface in instances where excavation is not necessary, such as decreasing seepage through a dam or containing groundwater pollution. Cement deep soil mixing also serves to improve the soil base, thereby increasing its strength and lowering the risk of liquefaction during seismic events.
