Outer Burial Containers and Vaults are used when earth burial is requested. An Outer Burial Container is a concrete form with top cap that houses the casket in the earth and prevents the collapse of the grave over time. Outer Burial Containers do not have liners or seals that prevent the entrance of water or other elements of the earth into the receptacle.

Burial Vaults are similar in form and function in that they are constructed of high strength concrete with a top cap that shelters the casket and the deceased and prevents the collapse of the grave over time. Burial Vaults do, however, incorporate liners and sealant materials that are placed to prevent the entrance of water and other elements of the earth into the receptacle.

The purchase of a vault may depend on the cemetery you have choosen. Each cemetery has their own set of guidelines that have to be followed.
