Soil mixing
Applications
Applications of soil mixing:
• Cut-off walls
• Lining walls
• Structurally load-bearing support elements (installing
steel beams in freshly mixed pile)
• Infilling elements between support piles or lining
supports
• Column-shaped or block-shaped support elements
• Area-wide soil improvement
• Stabilisation columns
Soil types
Soil mixing is particularly well suited for non-cohesive
mixed soils (gravel/sand mixtures). Soil mixtures of
gravel and coarse silt are equally suitable. Stones
present in the soil are not a problem provided they are
no larger than fist size. In cohesive soil types it is not
usually possible to completely mix the soil through with
binding agent. Furthermore, only a low stability can be
achieved in cohesive soils.
Advantages
• Vibration-free
• Low noise level
• High productivity
• Variable arrangement of columns
• No aggregates required
• Environmentally friendly
• Applicable in contaminated soils (no excavated soil)
