Outer burial containers consist of grave liners and burial vaults. These serve to enclose the casket or coffin in a grave. When caskets are buried under the ground, some cemeteries require a burial vault or a grave liner surrounding the casket. An outer burial container suffices to support the soil that is around the casket. This firm support is required to prevent the soil on top of the casket and around it from collapsing. Significantly, this ultimately serves to enhance maintenance in cemeteries, keeping cemetery grounds in great condition.
Important features
Burial vaults are caskets for the main caskets. They encase the main casket completely, from all sides. A grave liner merely acts as a cover for the top and sides of the casket. The bottom of the main casket is in direct contact with the ground. Both burial vaults and grave liners are typically made of concrete and lined with a layer of plastic or metal. Some are available, nowadays, in steel, copper, and bronze. These metal ones are sturdier but may cost more as they assure durability more than concrete does. Concrete may be prone to cracks over a period of time.
Some considerations
Your choice, a grave liner or a burial vault, totally depends on you as an individual or your family that decides on such matters. If cost is a consideration in selecting an outer burial container, then a grave liner will be ideal. Usually, these can be purchased as separate from the main casket (which depends on your selection again) from the funeral home that you are associated with. You may have a limited choice as some funeral homes carry only one or two models.
You may buy these as part of your main casket expense if your main casket manufacturer sells these. Retailers also sell grave liners and burial vaults. If you buy these online, they may incur high shipping costs, as they are heavy and have to be handled with care.
