Abstract
A hazardous material storage area has a reactive multi-layer composite mat which lines an opening into which a reactive backfill and hazardous material are placed. A water-inhibiting cap may cover the hazardous material storage area. The reactive multi-layer composite mat has a backing onto which is placed an active layer which will neutralize or stabilize hazardous waste and a fronting layer so that the active layer is between the fronting and backing layers. The reactive backfill has a reactive agent which can stabilize or neutralize hazardous material and inhibit the movement of the hazardous material through the hazardous material storage area.
Claims8
A reactive multi-layered composite mat for hazardous waste containment comprising:
- a first water permeable active layer, wherein said first active layer includes at least one reactive agent for stabilizing a constituent present within hazardous waste;
- a second water permeable active layer, said second active layer including at least one reactive agent for stabilizing a constituent present within a hazardous material;
- a backing material opposite a first side of said first active layer;
- a barrier material separating said first active layer from said second active layer;
- and,
- a fronting material positioned opposite said second active layer so that said first and second active layers are positioned between said backing and said fronting materials and separated therebetween by said barrier material.
