Which type of arrangement typically requires an air seal burial vault?

An air seal burial vault is specifically designed to protect the casket and its contents from external elements such as water, soil, and pests, ensuring that the integrity of the burial site is maintained over time. This type of vault is particularly required in traditional ground burials, where the casket is placed underground. In this scenario, the vault serves multiple purposes: it provides structural support to the grave, prevents the ground from collapsing, and protects the casket from the weight of the earth above.

In contrast, above-ground entombment, green burial, and cremation involve different methods of handling remains that do not necessitate an air seal burial vault. For example, entombment typically uses mausoleum structures that are not buried in the ground, while green burials prioritize the natural decomposition of the body, often foregoing the use of concrete or metal vaults. Cremation involves the reduction of the body to ashes and does not require any type of vault at all. Thus, traditional ground burial is the scenario where an air seal burial vault is essential.
