Abstract
A method of chemically and physically treating unconsolidated soils, over burden, fill and certain waste materials (the “ground”), or partly consolidated materials that can be excavated and broken up by normal earth moving and soil mixing equipment. This treatment results in the reduction of permeability in the ground, and as a result permits the prevention or control of contaminant migration from a site containing ground wastes of various types, thereby isolating these wastes.
