Burial Vaults Explained: Types, Costs, and Requirements
Burial vaults are outer burial containers surrounding caskets underground, protecting caskets from soil weight and grave collapse while preventing ground settling that would create cemetery maintenance challenges. Made from concrete, metal, polymer, or combination materials, burial vaults range from simple $700 concrete boxes to elaborate $10,000+ bronze-lined vaults marketed as protective alternatives to direct earth burial. Most cemeteries require vaults (or grave liners) not for legal reasons but to maintain level grounds simplifying mowing and landscaping.
Understanding what burial vaults do (and don’t do), cemetery requirements, types, costs, and alternatives helps families make informed decisions about this significant funeral expense that’s often cemetery-required but not legally mandated by California law.
This comprehensive guide explains burial vaults, their purpose, types, pricing, requirements, and whether they’re necessary.

What Is a Burial Vault?
Outer containers protecting caskets underground.
Definition
Burial vault: – Large box enclosing casket completely – Placed in grave before casket lowered – Casket set inside vault – Vault lid placed on top – Protects casket from earth and weight above
Purpose
Why vaults exist:
Prevents grave collapse: – Caskets eventually break down underground – Soil falls into space, creating depression – Grave sinks creating hazard – Vault maintains ground level
Cemetery maintenance: – Level grounds simplify mowing – Prevents equipment damage – Maintains aesthetic appearance – Reduces ongoing maintenance costs
Casket protection: – Shields from soil pressure – Prevents casket crushing – Keeps dirt and water away from casket – Marketed as “protective” feature
Materials
Common vault materials: – Concrete (most common) – Metal-lined concrete – Reinforced polymer plastic – Stainless steel or bronze (rare, expensive)
Installation
How vaults are placed: – Vault bottom lowered into grave – Casket placed inside vault – Vault lid positioned on top – May be sealed with caulk/sealant – Grave filled with dirt
Vault vs. Grave Liner
Two types of outer burial containers.
Grave Liner
Basic protection: – Concrete box covering top and sides only – No bottom piece – Casket rests on earth – Simplest outer container – $700-$1,500 – Satisfies cemetery requirement at minimum cost
Purpose: – Prevents ground collapse – Minimum cemetery requirement – No frills protection
Burial Vault
Complete enclosure: – Top, bottom, and all four sides – Fully enclosed container – Casket completely surrounded – May have reinforcement, lining, sealing – $1,200-$10,000+
Purpose: – Prevents collapse AND protects casket – May resist water entry – Various quality levels available – Marketed as superior protection
Which Do You Need?
Cemetery requirements: – Some require “vault or grave liner” – Either satisfies requirement – Grave liner is less expensive option – Vault offers more protection but costs more – Check specific cemetery policy
Types of Burial Vaults
Various vault styles and protection levels.
Basic Concrete Grave Liner
Minimum option: – Plain concrete, no lining – Covers top and sides – No bottom – $700-$1,500 – Satisfies cemetery requirements – Basic functionality
Unlined Concrete Vault
Complete box: – Concrete bottom, sides, top – Fully enclosed – No interior lining – $1,200-$2,000 – Better than liner but still basic – Adequate protection
Lined Concrete Vaults
Plastic or polymer lined:
Features: – Concrete outer shell – Plastic/polymer liner inside – Resistant to water seepage – Protects against elements – $2,000-$4,000 – Mid-range quality
Metal-lined vaults: – Concrete with metal (copper, stainless steel) lining – Better water resistance – More durable – $3,000-$6,000 – Premium protection level
Reinforced Vaults
Heavy-duty construction: – Extra-thick concrete – Steel reinforcement bars – Designed for heavy loads – $2,500-$5,000 – Maximum strength
Premium Sealed Vaults
Highest protection: – Reinforced concrete – Premium metal lining (bronze, stainless steel) – Gasketed seal between lid and base – Butyl sealant – $4,000-$10,000+ – Top-of-line option – Marketed as “permanent protection”
All-Metal Vaults
Rare specialty: – Solid stainless steel or bronze – No concrete – Extremely durable – $7,000-$15,000+ – Uncommon due to cost – Used rarely for prestigious burials
Costs and Pricing
Vault expenses vary significantly.
Price Ranges
By type: – Basic grave liner: $700-$1,500 – Unlined concrete vault: $1,200-$2,000 – Plastic-lined vault: $2,000-$4,000 – Metal-lined vault: $3,000-$6,000 – Premium sealed vault: $4,000-$10,000 – Luxury vaults: $10,000-$15,000+
Additional Costs
Installation: – Vault installation/sealing: $100-$400 – Often included in cemetery fees – Labor for placing and sealing – Equipment rental
Delivery: – Delivery to cemetery: $50-$150 – May be included in vault price – Distance affects cost
What Affects Price
Cost factors: – Materials (concrete vs. metal-lined) – Thickness and reinforcement – Interior lining quality – Sealing features (gaskets, sealant) – Brand/manufacturer – Weight and size – Warranty offered
Most Common Purchase
Typical family: – Mid-range lined vault: $2,000-$4,000 – Balances cost and protection – Satisfies cemetery requirements – Adequate quality – Most popular choice
Are Burial Vaults Required?
Understanding legal vs. cemetery requirements.
Not Required by California Law
State law: – California does NOT require burial vaults – No legal mandate – State allows direct earth burial – Caskets can be buried without vaults legally
Required by Most Cemeteries
Cemetery policies: – Individual cemeteries set own rules – Most require vault or grave liner – Private cemetery prerogative – Not a legal requirement but cemetery rule
Why cemeteries require vaults: – Prevents ground settling – Maintains level lawn – Easier grounds maintenance – Protects mowing equipment – Aesthetic appearance – Reduces labor costs
Exceptions
Cemeteries NOT requiring vaults: – Green burial grounds (typically) – Some religious cemeteries – Natural burial sections – Private family cemeteries – Some rural cemeteries
Check before purchasing: – Ask cemetery about requirements – Get policy in writing – Some have vault-free sections – May allow direct burial with signed waiver
What Vaults Do and Don’t Do
Realistic expectations about vault protection.
What Vaults DO
Actual benefits:
Prevent ground settling: – Main purpose achieved – Maintains level cemetery grounds – Prevents depression over grave – Long-term structural support
Protect casket from soil weight: – Thousands of pounds of soil above – Vault bears weight instead of casket – Prevents casket crushing – Structural integrity maintained
Slow water entry: – Quality vaults resist ground water – Sealed vaults especially effective – Delays water reaching casket – Keeps casket cleaner longer
Peace of mind: – Families feel better knowing casket protected – Psychological comfort – Shows respect and care
What Vaults DON’T Do
Common misconceptions:
Do NOT prevent decomposition: – Bodies decompose naturally regardless – Vaults don’t stop biological process – Even sealed vaults only slow, not prevent – Marketing implies more than reality
Do NOT provide permanent protection: – Concrete cracks over decades/centuries – Seals deteriorate – Water eventually enters – “Permanent” is misleading – No container lasts forever
Do NOT preserve body: – Preservation requires embalming – Even then, not permanent – Vault alone doesn’t preserve – Combined with embalming, slows but doesn’t stop decay
Do NOT prevent all water: – Ground water eventually seeps through – Even sealed vaults leak eventually – Can slow water significantly – But not permanent barrier
Marketing vs. Reality
Industry claims: – Vault companies market “eternal protection” – Imply permanent preservation – Create emotional appeal – Reality: Vaults delay processes, don’t prevent them
Alternatives to Vaults
Options when vaults aren’t required.
Direct Earth Burial
No vault: – Casket buried directly in earth – Traditional burial method for millennia – Natural decomposition – Least expensive option (no vault cost)
Where allowed: – Green burial grounds – Natural cemeteries – Some rural cemeteries – Private property (with permits)
Benefits: – Saves $700-$4,000 – More environmentally natural – Simpler process – Aligns with green burial values
Green Burial Containers
Biodegradable options: – Shrouds or burial blankets – Simple pine boxes – Wicker or willow caskets – Cardboard containers
Purpose: – Return to earth naturally – No barriers to decomposition – Environmentally friendly – Usually cheaper than vaults
Cremation
Avoiding burial entirely: – Cremation eliminates need for vaults – Ashes in urn buried (no vault needed) – Or ashes scattered – Much less expensive overall
Mausoleum Entombment
Above-ground burial: – No need for vaults – Casket in above-ground crypt – Sealed in mausoleum – Different protection method
