A bead (10) for forming a barrier layer over an underwater surface. Gen- erally, a plurality of such beads are re- quired to form an effective underwater barrier layer. Each of the beads comprises a core (11), preferably formed of a piece of gravel. A sealant layer (12) is provided which at least partially encapsulates the 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 an underwater bar- rier layer over contaminated sediments be- neath a body of water, a plurality of the beads are deposited on top of the contam- inated sediments.
Perle (10) utilisée pour former une couche de barrage sur une surface subaquatique. Généralement, une pluralité de ces perles est nécessaire pour former une couche de barrage subaquatique efficace. Chaque perle est constituée d'un noyau (11) se composant, de préférence, d'un morceau de gravier. Le noyau est au moins partiellement enrobé d'une couche de scellement (12) comprenant une argile et un liant. Le liant facilite l'adhésion de la couche de scellement au noyau de la perle. Pour former une couche de barrage sur des sédiments contaminés se trouvant au fond d'un plan d'eau, on dépose une pluralité de perles sur lesdits sédiments contaminés.
