What are burial vaults and grave liners?
These are the outside containers into which the casket is placed. Burial vaults are designed to protect the casket and may be made of a variety or combination of materials including concrete, stainless steel, galvanized steel, copper, bronze, plastic or fiberglass. A grave liner is a lightweight version of a vault which simply keeps the grave surface from sinking in.
Must I purchase a burial vault?
Most large, active cemeteries have regulations that require the use of a basic grave liner for maintenance and safety purposes. Either a grave liner or a burial vault will satisfy these requirements. Some smaller rural or churchyard cemeteries do not require use of a container to surround the casket in the grave.
