Abstract
A method is described for the confinement and isolation of waste materials, especially those that are toxic or otherwise hazardous such as radioactive wastes. The waste material, either contained or uncontained, is emplaced in a underground or surface excavation and encased with backfill or barrier material formed of molten modified sulfur cement or modified sulfur concrete that then cools into a hard, durable, corrosion resistant mass.
