What's a burial vault, and when might you need one?
Burial vaults fall under the category of "outer burial containers" - any structure encasing the casket when it goes into the earth. Outer burial containers can be as simple as grave liners - unfinished concrete slabs that sit around the casket - or they can be as opulent as air sealed burial vaults that lock around the casket.
The purpose of an outer burial container is primarily to support the earthload that surrounds and sets on top of the casket. This prevents the grave from sinking in over time, and also simplifies lawn care for the groundskeepers. Sealed burial vaults may delay the natural progression of decomposition, but it is impossible for any casket or burial container to indefinitely postpone the onset of decomposition.
According to the FTC, outer burial containers are not required by state law anywhere in the U.S.. That said, individual cemeteries may have their own policies, and they may require the use of outer burial containers.
Requirements can vary based on where exactly in the cemetery the grave is located, so if you have your heart set on a specific area of a cemetery, be sure to let them know.
