Most cemeteries require an outer burial container for casketed burials, because the vault keeps the ground from settling as the casket and soil shift over time. This requirement is about grounds maintenance and safety as much as protection, and it is standard across most of the Dallas, Texas area. Families are sometimes surprised to learn the vault is effectively mandatory.
What varies is the level of container a cemetery will accept, from a basic grave liner to a fully sealed vault. Knowing a specific cemetery's rules before selecting helps avoid surprises, and a Doric Vaults dealer or funeral home in the Dallas area can confirm what a given cemetery requires and match it to an appropriate vault.
