Vaults
If you choose burial after the cremation, it's important to understand why you need
an urn vault and that they do not all provide the same protection.
There are several
factors that challenge the integrity of an urn vault. Heavy equipment necessary
for maintaining the cemetery grounds passes over the urn vault during cemetery operations.
Ground water, too, is an important factor; A lined urn vault is constructed using
high strength concrete. Lined urn vaults are reinforced in one of two ways: with
durable plastic or with a combination of durable plastic and metal. Each lined urn
vault provides the long-lasting protection needed to resist these elements over
time.
In most areas of the country, state or local law does not require that you
buy a container to surround the urn in the grave. However, many cemeteries require
that you have such a container so that the grave will not sink in. Either a grave
liner or an urn vault will satisfy these requirements.
