What is the purpose of a burial vault?

The purpose of a burial vault is primarily to protect the casket and its contents from the external environment, which is crucial for maintaining the integrity of the burial site over time. This protection helps to ensure that the ground does not settle and that the casket remains in a stable condition after interment. Burial vaults are typically made from durable materials such as concrete or metal, which serve to shield the casket from soil weight, water intrusion, and other environmental factors.

While enhancing the cemetery landscape may contribute to the overall aesthetics of the site, the primary function of a burial vault is about safety and preservation rather than decorative purposes. Other options suggest functions that do not accurately represent the primary roles of a burial vault. For instance, reducing burial costs or simplifying the excavation process do not align with the main purpose, as burial vaults are intended to provide structural support and longevity rather than serve as cost-saving measures or facilitate easier digging.
