solidification/stabilisation (S/S) is a process which physically binds or encloses contaminants within a stabilised mass and is performed both ex situ and in situ. This technology reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means.

Ex situ S/S requires excavation of the material to be treated, and the resultant material must be disposed.

In situ S/S uses auger/caisson systems and injector head systems to add binders to the contaminated soil or waste without excavation, and the resultant material is left in place.
