ABSTRACT:
A cap for sealing waste in a landfill is prepared by disposing a fill layer atop the waste and applying a fast-curing elastomeric material to the fill layer to provide a monolithic, continuous, elastomeric coating thereupon. The elastomeric material is derived from the reaction of an isocyanate-terminated compound having at least two reactive isocyanate groups and an amine-terminated compound having at least two reactive amine groups. The elastomeric layer is preferably covered with a porous drainage layer which is in turn covered with a layer of soil.
