Method of sealing permeable unconsolidated materials

摘要: Methods of forming layers material upon or below the earth's surface and above water table to prevent effectively inhibit flow groundwaters through such laters initially unconsolidated materials. Chemical components are added materials as incinerator ash other waste deposited in a landfill operation create alkaline conditions which, when contacted by water, induce precipitation calcite sufficient quantities produce cementing action which retards leachate formation. In another aspect, site is prepared for use with an essentially hydraulically sealed sub-base choosing soils carbonate bedrock adding appropriate chemical cause precipitate may be applied directly naturally occurring precipitation. yet low level radioactive potentially hazardous wastes disposed placing containers underground chambers filling balance buffer zone precipitated provide retard incursion zone.
