In most areas of the country, state or local law does not require that you buy a container to surround the casket in the grave. However, many cemeteries require that you have such a container as the outside receptacle keeps the earth from settling so that the grave will not sink in. This also prevents the land from becoming uneven, making the cemetery less attractive. Finally, it allows cemetery caretakers to more easily maintain the landscape, which is an advantage to you in a more beautiful cemetery at a lower cost. Either a grave liner or burial vault will satisfy these requirements.
A vault provides more durability than a grave liner. The vault is usually selected by the family because of their desire for further protection of their loved one in addition to the casket. There are many types of vaults and we would be happy to show you the differences.
