CHEMICAL STABILIZATION OF LANDSLIDES BY ION EXCHANGE

The factors responsible for the unique physical behavior of clay include an electrical charge on their molecular structure, as well as certain colloidal properties, and water holding capacity. The nature of ions satisfying the electrical charges, in turn, strongly influence the physical properties of clay. No single chemical or group of chemicals is available that will universally improve all types of clay minerals in all chemical environments; nevertheless, field application of selected chemicals has been successfully used to halt active landslides, to reduce expansive clay properties, and to strengthen clay masses. After the appropriate chemical has been selected a small amount of concentrated solution is applied in place to the clay through tension cracks and/or drill holes. The method described here is the result of 12 years of laboratory studies and field testing.
