Abstract
Containers of chemical hazardous waste materials can be permanently vaulted by distributing the containers on a base surface apart from one another and thereafter filling the space between the deposited containers with a cementitious substance and covering the containers with a slab of cementitious substance whereby each individual container is isolated within a structural skeleton of the cementitious substance. The cementitious material will retain its structural integrity after the container has deteriorated or corroded. Multiple tiers of containers may be accumulated in this fashion and encapsulated within a permanent disposal vault.
Claims5
A method for encapsulating containers which comprises:
- (1) establishing a base surface;
- (2) depositing said containers on said base surface apart from one another;
- (3) establishing wall forms around a preponderance of the perimeter of deposited containers;
- (4) applying a cementitious substance within said wall forms to the said base surface to fill the space between said deposited containers and covering said deposited containers;
- (5) leveling the top of said cementitious substance within said wall frames to form a cover slab at least two inches thick above said deposited containers and to form a second tier base surface;
- (6) hardening said cementitious substance to form a monolithic block including the said cover slab and the said space between said deposited containers.
A vault for permanent disposal of containers of waste materials comprising:
- water impermeable basin having a liquid-confining basin liner which is located above the high water table of the region;
- multiple individual containers, each containing waste materials, said containers being spaced apart from one another;
- cementitious filler forming a monolithic block below, above and between said containers;
- water impervious incapsulation film surrounding said monolithic block;
- monolithic water impermeable incapsulation for the said incapsulation film;
- covering for said vault being contoured to accommodate the existing surface grade.
