Soil/Sludge Solidification and Stabilization

The solidification of soil, solid wastes and sludges is beneficial for many reasons including:

		•	Allowing bulk haulers to transport waste safely
		•	Making waste acceptable by disposal facilities
		•	Reduces disposal costs when compared to sludge disposal
		•	Solidification can be used as an odor reducing method

PSC utilizes various agents for soil/sludge solidification including cement, fly ash, various grades of lime, clay, ground corncobs or commercial proprietary agents. PSC performs stabilization of impacted soil and sludge both in-situ and ex-situ as site conditions permit.

PSC engineers solutions for on-site stabilization by performing treatability studies with representative samples in our laboratories to determine the most cost effective recipe of admixtures.

Advantages of on-site stabilization include:

		•	It renders heavy metals, volatile organics and sulfides in soil/sludge less harmful
		•	Verification of treatment success is easily obtained
		•	Often lowers or eliminates T&D costs, while removing the potential liability associated with off-site disposal
