The formal use of a grave involves several steps with associated terminology. ;Grave cut The excavation that forms the grave. Excavations vary from a shallow scraping to removal of
topsoil to a depth of or more where a vault or
burial chamber is to be constructed. However, most modern graves in the United States are only deep as the
casket is placed into a concrete box (see
burial vault) to prevent a sinkhole, to ensure the grave is strong enough to be driven over, and to prevent floating in the instance of a flood. ;Excavated soil with its soil next to it awaiting to be closed The material dug up when the grave is excavated. It is often piled up close to the grave for backfilling and then returned to the grave to cover it. As soil decompresses when excavated and space is occupied by the burial not all the volume of soil fits back in the hole, so often evidence is found of remaining soil. In cemeteries, this may end up as a thick layer of soil overlying the original ground surface. ;Burial vault , the

Turku, Finland A
burial vault is a structure built within the grave to receive the body. It may be used to prevent crushing of the remains, allow for multiple burials such as a family vault, retrieval of remains for transfer to an
ossuary, or because it forms a monument. ;Grave backfill The soil returned to the grave cut following burial. This material may contain artifacts derived from the original excavation and prior site use, deliberately placed goods or artifacts, or later material. The fill may be left level with the ground or mounded. ;Monument or marker
Headstones are best known, but they can be supplemented by decorative edging,
footstones, posts to support items, a solid covering or other options. == Graveyards and cemeteries ==
