Soil Remediation
Solidification and Stabilization (S/S) is a widely applied treatment for managing soils that have been classified as hazardous due to the containment of a wide range of wastes. S/S has been in use in different parts of the country since the early 1950's.
The S/S process involves blending Portland cement with the contaminated soil resulting in the hazardous material being tied up both chemically and physically. Using the cement as a binding agent the new product has been chemically altered. The hydration of the cement also reduces the permeability of the soil reducing the potential for leaching action to occur.
The benefit of the S/S process is that the contaminated media may be treated in place (in-situ), reducing further relocation or continuing treatment costs. S/S is the ideal treatment for rehabilitating Brownfield sites (i.e. industrial contaminated sites) or specific sites that may have become contaminated due to localized spills.
