A sprayable composition and a method of protecting material with the composition is disclosed. The composition comprises a bulking/setting material, a water soluble polymer and water to provide a cover layer which, after spraying, is tough, flexible and water-repellent. Other materials such as clay, fibrous material, a foam producing agent and a hardening retarder can be included in the composition. The composition is effective as a cover layer over material such as soil, refuse at a dump site, stockpiled material, a temporary cover for remediation sites, or tire piles.

In a method of creating a seal in a subsurface environment, a plurality of manufactured composite particles are placed in the subsurface environment, the composite particles including a sealant material. The sealant material is hydrated to create a cohesive seal. In a method of controlling erosion of a periodically or continuously inundated surface, a plurality of manufactured composite particles are placed around erosion-control objects. The composite particles include a sealant material which is a cohesive, low-permeability material when hydrated. The sealant material physically stabilizes the erosion-control objects on the surface. The invention also relates to compositions and properties of the composite particles.

A method for containing or removing contamination from a substrate includes applying a material such as a polyurea elastomer to the contaminated substrate. Preferably, the material sets in less than about 1 hour and is substantially unaffected by exposure to radiation. The contaminants can be contained or shielded on the substrate by the material to reduce exposure to the contaminants. In one preferred embodiment, this invention relates to the encapsulation of objects or surfaces to shield persons in the area from contamination. Alternatively, the material can be removed from the substrate to remove contaminants. Preferably, the material provides a Decontamination Factor of at least about 10. In another preferred embodiment, the material is applied hot to the contaminated substrate to increase its effectiveness in removing contaminants. The present method can also prevent contamination of an uncontaminated substrate.

A flowable material to isolate or treat a surface consists of a plurality of manufactured composite particles. Each composite particle includes a core, and a sealant layer at least partially encapsulating the core. The core is relatively dense compared to the sealant layer, and the composite particle has a specific gravity greater than one. The sealant layer includes a clay mineral, a pozzolanic material and/or activated carbon. A sealant layer formed of a pozzolanic material creates a hardened underwater barrier layer. The sealant layer can also include natural fibers such as cellulose or man-made fibers such as glass, carbon or plastics to mechanically improve the geotechnical properties of the layer when hydrated. The composite particles can also include a material to treat the contaminants or otherwise improve the surrounding environment.

Fiber-containing composite particles and fiber-reinforced barrier matrix compositions made from them are disclosed. The composite particles include a core, a hydratable clay mineral layer, an optional protective coating, and a reinforcing fiber. The fiber may be present in any or all of several locations: adhered to the core, dispersed in the hydratable layer or in the protective coating. Upon hydration, the hydratable clay mineral layer swells and forms a matrix that cohesively holds the fibers and the core in a fiber-reinforced barrier matrix composition.

A bead for forming a barrier layer over an underwater surface. Generally, a plurality of such beads are required to form an effective underwater barrier layer. Each of the beads comprises a core, preferably formed of a piece of gravel. A sealant layer is provided which at least partially encapsulates this core. The sealant layer includes a clay and a binder. The binder facilitates the adhesion of the sealant layer to the core of the bead. To form such an underwater barrier layer over contaminated sediments beneath a body of water, a plurality of the beads are deposited on top of the contaminated sediments.

A sealant product to form a reactive seal in a subsurface or intermittently subaqueous environment includes a reactive medium and a hydratable material that when hydrated forms the seal. For example, the reactive medium may be a zero-valent metal, a reduced metal, shredded tires, and any combinations thereof. A method of forming a reactive seal comprising applying a sealant product in a subsurface or intermittently subaqueous environment to form the seal.

A method of treating a metal-contaminated sediment includes capping the sediment with a capping product containing sulfur and at least one component selected from the group consisting of clays, clay-sized materials, bulking agents, sand, sand-sized materials, aggregate, and binding agents. A capping product includes a plurality of manufactured composite particles, each composite particle comprising a relatively dense core and a sealant layer at least partially encapsulating the core, the sealant layer including sulfur and at least one of the above components.
