Soil Stabilisation is essentially a mixing process that can be carried out in a number of ways. Normally it is an in-situ process where the binders are mixed into the ground in a layer by a powerful rotovators and then compacted with a roller. The layer is nominally 300mm but any number of layers can be used.

For smaller sites tractor mounted rotovators are available but these still have a very powerful mixing action. Binders can be applied by spreading them on the ground before mixing or they can be applied during the rotovation process. The latter method eliminates any potential dust problems.

For less cohesive materials it is possible to mix the soil and binders at a central mixing plant. This will involve hauling the soil to the plant for treatment and returning it to the point of deposition. This is usually slower than the in-situ method.
