In situ modification of active clays for shallow foundation remediation
This paper presents a tested technique, which involves using a aqueous solution of potassium and ammonium ions to treat expansive clay soils in remediation of damaged structures. The technique relies on reactions between the solution ions and the clay soil to adjust rheological properties of the clay. Mechanism by which potassium and ammonium treatment reduce swelling motions and pressures are described herein. A case history of a forty-five year old building damaged by both heave and shrinkage movements is presented. Identification of movement sources, reactivity laboratory testing of site soils with the aqueous solution, predicted injection and long term movements, description of the injection modification technique, verification quality assurance testing and foundation performance are presented
