What is a burial vault?

A burial vault is specifically designed as a protective container that encases the casket within it. Its primary purpose is to provide support and stability to the casket, ensuring that it does not collapse or sink over time due to the weight of the soil and the forces of nature. This structural integrity helps maintain the grave's appearance and can also protect the casket from moisture and other environmental factors, prolonging the condition of the casket and the remains inside.

This definition highlights the functional aspects of a burial vault, distinguishing it from other funeral-related items. For instance, decorative caskets serve an aesthetic purpose rather than providing structural support, while memorial services focus on honoring the deceased rather than the physical aspects of burial. Additionally, an urn is specifically designed for holding cremated remains and is therefore not applicable to the context of burial vaults.
