Burial vaults and grave liners are outer burial containers that enclose a casket in a grave. In the case of ground burial, most cemeteries require either a burial vault or a grave liner, in addition to the casket.
Burial vaults and grave liners are used to support the soil around the casket and ensure that the soil above and around the casket will not collapse, which ultimately serves to minimize cemetery maintenance and keep the cemetery grounds looking nice.
Basic Features Of Burial Vaults And Grave Liners
Both burial vaults and grave liners are outer containers that contain a casket if it is buried in the ground. A burial vault completely contains the casket, and functions almost like a casket for the casket. A grave liner only covers the top and sides of the casket and allows the bottom of the casket to be in contact with the earth.
Burial Vault Materials
Burial vaults and grave liners are often made of concrete and lined with plastic or metal, though they are also available in steel, bronze, and copper.
