A burial vault is a protective container placed in the ground to hold a casket. Made from materials like concrete, metal, or fiberglass, burial vaults help prevent the ground from settling and protect the casket from water, soil, and other elements. They are often used in cemeteries to maintain the integrity of the burial site. Many cemeteries require burial vaults to ensure that graves remain stable and to facilitate maintenance. While some families choose simple designs, others may opt for more elaborate styles. The use of burial vaults is common in various cultures and is often associated with traditional funeral practices.
