Soil Mixing Wall - Raito, Inc.

Soil Mixing Wall uses multiple auger, paddle shafts rotating in alternating directions to mix in-situ soil with cement grout, bentonite slurry, clay slurry, or other stabilizing reagent slurries to install continuous subsurface soil-cement walls for excavation support and groundwater or underground pollutants control, or ground reinforcement; column blocks, lattice, or areal patterns for stabilization. The soil-cement is usually reinforced with steel H-piles when used for excavation support along with groundwater control. Applicable subsurface soils are soft to hard silt and clay, loose to very dense sand, gravel, a cobble soils, cobble and boulder soil and bedrock with predrilling.

Deep Soil Mixing - Raito, Inc.

Deep Soil Mixing method is an in-situ soil mixing technology that mixes existing soil with cementitious materials using mixing shafts consisting of auger cutting heads, discontinuous auger flights, and mixing paddles. The mixing equipment varies from single to six augers configurations depending on the purpose of the deep mixing. The soil-cement produced generally has higher strength, less compressibility, and lower permeability than the native soils. Deep Soil Mixing is effective for liquefaction mitigation of seismically sensitive soil layers, foundation improvement under future structures and in-situ stabilization of contaminated soils for environmental remediation among other uses.
