Grave liner
A concrete or composite box that lines the grave and supports the soil above the casket so the ground does not sink. A cheaper, unsealed alternative to a burial vault.
Most cemeteries require either a grave liner or a vault so that heavy maintenance equipment can drive over graves without the ground caving in as a casket deteriorates. A liner covers the top and sides but is not sealed, which makes it the budget option — typically $700–$1,500 versus $1,000–$10,000 for a vault.
No state law requires a liner or vault; it is a cemetery rule, not a legal one. If a cemetery requires outer burial containment, the liner is the minimum that satisfies it — the funeral home cannot require you to upgrade to a sealed vault.
Funeral homes profit more on sealed vaults and often present them as standard. If the cemetery only requires a liner, you can decline the vault and the “protective” sealing upgrade, which has no proven benefit.
- Vault— A concrete or metal box placed in the grave around the casket. Required by most cemeteries (not by state law) to keep the ground from settling as the casket decomposes.
- Cemetery plot— The piece of ground you buy for a burial. Paid to the cemetery, entirely separate from funeral-home charges.
