Soil mixing generally comprises three stages: premixing of the soil, injection of the binding agent and incorporation of the soil/binder mix. How the soil is mixed is a function of the rig/tool used. Common methods include:
- single auger mixing (DSM)
- cutter soil mixing (CSM)
- jet grouting
- shallow mass mixing
The technique produces very little spoil so is perfect for contaminated grounds.
The structures produced by soil mixing can be columns, panels or continuous trenches depending on the type of rig utilised.
The technique works with all types of loose soil which are free from coarse elements and facilitate dispersion of the binder.
