What is a vault and why is it required?
A vault is a re-enforced concrete box which is placed into a grave. The casket is then interred within the vault. The main purpose of the vault is to reduce ground settling. With less ground settlement, your grave will need less maintenance such as re-filling and seeding. It also serves as some protection to the casket. There are no vaults made which will completely seal out all water, dirt, etc. from the casket or keep it from deteriorating.
