ABSTRACT:
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.
