Soil Mixing

For wet soil mixing the mixing tools rotate around the vertical axis of the mixing shaft. The tools break up the soil matrix and mix the suspension with the soil. The binding agents used are usually cement types mixed to a suspension by adding water.

Procedure for 1-fold soil mixing

1. Positioning of mixing tool

2. Drilling down the mixing tool while injecting suspension

3. Mixing of the soil down to final depth

4. Extraction of the mixing tool and further thorough mixing while injecting suspension

5. Completed soil mixing column
