What is a double-depth interment?
A double-depth interment is the use of one burial space for the burial of two individuals. The grave is dug deeper than a normal grave to accommodate the placement of one vault and casket on top of another vault and casket. Often cemeteries have special sections and special vaults for double-depth burials. The operating custom and practice is that the top of the vault (single or double depth) should be 18-24 inches below the earth’s surface.
