Burial vaults are mandated by cemetery rules, not by law. The reason their use is dictated is because they not only protect the casket but they reduce the cemetery's long term maintainance costs. The earth doesn't settle as much and remains level over time. We use the Eagle Line of vaults. Although many are available, most families we serve use these two vaults:

Guardian Price $ 900.00

Eagle Sentinel Price $ 1100.00
