ABSTRACT:
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.
