Soil mixing enhances soil properties for engineering and remediation goals. It boosts bearing capacity, prevents liquefaction, controls groundwater, stabilizes excavation bottom, prevents deformation, and cleans up contaminated ground.
 

Soil mixing is the most effective for improving soil bearing capacity, preventing foundation settlement, and stabilizing contaminated soils. This technique has a wide range of applications and can be tailored to meet specific project needs.

Cutoff walls are used to exclude groundwater from an excavation, to minimize the requirement for dewatering pumping.  Typically, the method involves installing a very low permeability physical cut-off wall or barrier around the perimeter of the excavation to prevent groundwater from entering the working area.

Liquefaction prevention is a liquefaction remedial measure for existing structures where other remedial measures cannot be implemented. A perimeter soil-cement cutoff wall is recommended to installed to isolate cohesionless soils under the existing structure.

Raito has tremendous experience in excavation support systems including permanent and temporary excavation support walls, and has constructed numerous projects for buildings, transportation facilities, and other civil works projects.

Slope stabilization is important in the design of such excavations as open pits, quarries, and foundations, rock-fill dams, slopes of other types of embankments, and reservoirs, where movement may have serious consequences.
