Soil mixing method

Bodenmischverfahren

Environmentally friendly and economical
excavation support

We use the soil mixing method to produce vertical soil concrete columns in the ground. Soil mix columns are used as a deep foundation element and by overlapping the individual columns for sealing walls and excavation support.

Implementation

The in-situ soil is mixed with cement slurry or special mixtures using a guided mixing paddle to produce an earth concrete body. A continuous sealing wall is created by continuously lining up the earth concrete columns.

  • Erosion resistance for sealing walls

Applications

  • Excavation support in city centre areas with or without sealing effect
  • Sealing walls as part of flood protection projects
  • Production of foundation bodies
  • Strengthening of moderately load-bearing soils
  • Sealing off landfills and contaminated sites (in-situ immobilisation)
  • Sealing of earth dams with or without statical effect
