A METHOD FOR SEALING OF A MASS OF WASTE

摘要

The invention provides a new method for sealing off a mass of waste which comprises: surrounding the mass of waste, stabilized waste or its placement side with at least one substantially continuous layer of porous material, the layer defining a substantially continuous, waste-encompassing interface, and providing a sufficient amount of an interreactive reagent on either side of the interface for the reagents upon placement to diffuse towards each other and to form a precipitate filling the pores of said porous material substantially along said interface thereby forming a waste-encompassing layer of reduced permeability. The special benefit of this method is that after a rupture of the seal the interreactive reagents form a new seal, thus preventing loss of noxious substances through the rupture.
