What does an air seal burial vault refer to?

An air seal burial vault refers to a design that prevents air and water from entering the vault once it has been sealed. This is typically achieved by employing a dome-shaped lid that is lowered over the base of the vault during the burial process. The dome creates a secure closure that forms an airtight seal, which helps to protect the casket and its contents from external elements such as moisture and soil, thereby enhancing preservation.

This specific construction allows for a more secure environment, providing peace of mind for those making funeral arrangements. Alternatives to this design, such as open vaults or those made entirely of certain materials without the necessary sealing properties, do not offer the same level of protection and security that an air seal burial vault provides.
