  • Method and structure for hazardous waste containment
    Patent number: 4844840
    Abstract: Primary waste containers are placed in prefabricated canisters and sealed with a curable fluid sealant, such as grout. The canisters are then stacked in an interlocking manner to form a stable integrated structure. The containers are not, however, permanently attached to one another, so that individual containers are able to shift relative to one another in response to earth movements. In this way, the integrity of the individual container is maintained and the sealed wastes protected even when the integrated structure as a whole experiences significant stresses from earth movement.
