What Happens to a Body in a Burial Vault? The Science, Myths, and Realities
Christi AndersonWhen planning a traditional burial, many families wonder: what really happens to the body in burial vaults? This question is both practical and deeply personal. Understanding the science, process, and myths surrounding burial vaults can help you make informed decisions and find peace of mind during a difficult time. In this comprehensive guide, we’ll explore what a burial vault is, how it affects decomposition, what happens over time, and address common misconceptions.

What Is a Burial Vault?
A burial vault is a sturdy, lined outer container designed to house a casket underground. Its main function is to protect the casket from soil, water, and the weight of the earth above. Most cemeteries require vaults to prevent ground settling and to maintain the appearance of the landscape. Vaults are commonly made from concrete, metal, or high-strength plastic, and are often sealed to limit the entry of moisture and air.
How Does a Burial Vault Affect Decomposition?
The presence of a burial vault significantly changes the decomposition process. In a natural burial, the body is in direct contact with soil and microorganisms, which accelerates decomposition. However, a body in burial vault is shielded from many of these elements. The sealed environment inside the vault reduces oxygen and moisture, which are essential for rapid breakdown. As a result, decomposition occurs much more slowly than in a simple grave.
| Burial Type | Decomposition Speed | Environmental Impact |
|---|---|---|
| Traditional Burial (Vault) | Slow | Low soil contamination, less ground settling |
| Natural Burial (No Vault) | Faster | Higher soil interaction, more ground settling |
What Happens to a Body in a Burial Vault Over Time?
Let’s break down the stages a body in burial vault typically undergoes:
- Initial Stage: If the body is embalmed, preservation lasts for a short period. Embalming slows, but does not stop, decomposition.
- Intermediate Stage: As oxygen is depleted inside the vault, anaerobic bacteria begin to break down tissues. This process is much slower than in open soil.
- Long-Term Stage: Over decades, the body will eventually skeletonize. However, the sealed environment of the vault can delay this process for many years, sometimes even longer.

Why Do Cemeteries Require Burial Vaults?
Burial vaults serve several important purposes:
- Ground Stability: Vaults prevent the ground from caving in, making cemetery maintenance easier and safer.
- Protection: They shield the casket from water, insects, and shifting soil, preserving the grave’s integrity.
- Peace of Mind: Many families find comfort knowing their loved one’s resting place is protected from the elements.
Common Myths About Burial Vaults
There are several misconceptions about what happens to a body in burial vault. Some believe that vaults preserve the body forever, but this is not the case. While vaults slow down decomposition, they do not halt it entirely. Vaults are not completely airtight, and over time, moisture and gases can still enter, allowing for gradual breakdown. The process is simply much slower than in a natural burial.
Environmental Considerations
While burial vaults offer protection and stability, they also have environmental impacts. The production of concrete and steel vaults requires significant resources and energy. Some families are now considering eco-friendly alternatives, such as biodegradable vaults or natural burials, to reduce their ecological footprint. It’s important to weigh these factors when making burial decisions.
