Basic vault
models come with a 75 year warranty. Some people simply want the minimum vault that meets the requirements of the cemetery. For them, we have available either an unlined minimum vault or an unsealed grave liner.
In most areas of the country, state or local law does not require that you buy a container to surround the casket in the grave. However, many cemeteries require that you have such a container so that the grave will not sink in. Either a burial vault or a grave liner will satisfy these requirements.
