Our state laws do not require a vault for burial. However, most cemeteries do require an outside container for the casket. The purpose is two-fold: First, the outside receptacle keeps the earth from settling, thus preventing the unevenness of the land which makes the cemetery less attractive. Second, it makes it easier for cemetery caretakers to maintain the landscape, which is an advantage to you in a more beautiful cemetery at a lower cost. 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.
