Why Urn Vaults Are Essential for Safe Ground Burial
An urn vault for ground burial is a protective outer container that shields cremation urns from soil pressure, moisture, and cemetery maintenance equipment. Most cemeteries require these vaults to prevent ground settling and maintain burial plot integrity.
Quick Facts About Urn Vaults:
- Purpose: Protect cremation urns from earth weight and environmental damage
- Materials: Polymer, concrete, steel, cultured marble, or bronze
- Standard Size: 15" L × 15" W × 18" H (low-profile: 14" H)
- Cost Range: $49.95 to over $1,000 depending on material and features
- Requirements: Most U.S. cemeteries mandate vault use for ground burial
Without proper protection, wooden, ceramic, or thin metal urns can collapse under soil pressure and moisture. This creates sunken graves that are distressing for families and costly for cemetery maintenance.
Polymer urn vaults are accepted by most cemeteries and cost significantly less than steel or concrete alternatives, while providing 1000 psi strength - stronger than traditional concrete vaults. Some durable urns made of cultured marble or cast bronze can serve as their own vault if they meet compression testing requirements.

What Is an Urn Vault & Why Cemeteries Require One
An urn vault for ground burial is a protective outer container that creates a safe barrier between the urn and underground conditions - from shifting soil to heavy maintenance equipment.
The purpose is protection. Without a vault, cremation urns face serious challenges underground. Wooden urns absorb moisture and decay. Ceramic urns crack under soil weight. Metal urns can corrode or get crushed over time.
When urns fail underground, you get "ground settling" - the grave sinks in. It's heartbreaking for families and creates maintenance headaches for cemetery crews.
Understand the difference: Your urn holds cremated remains. The urn vault is the protective outer container. A combination urn-vault does both jobs in one piece.
Most cemeteries require vaults for ground burial because they've learned from experience. Cemetery superintendents have seen problems when urns go into the ground without protection.
Urn vaults for ground burial come in materials from affordable polymer to premium bronze, so there's usually an option that fits your budget and cemetery requirements.
Key Functions of an Urn Vault
A quality urn vault for ground burial handles four main protection jobs:
Soil pressure creates tremendous downward force - 1000+ PSI in many cases. Good vaults are engineered to handle this pressure, spreading the load across their reinforced structure.
Equipment protection is crucial. Cemetery maintenance means heavy machinery - mowers, utility vehicles, construction equipment. When these roll over burial sites, extra weight transfers through soil. A vault with a strong lid protects against this dynamic loading.
Moisture barriers keep groundwater from reaching wooden urns (which would rot), metal urns (which could corrode), or creating conditions where remains might be disturbed.
Long-term integrity keeps burial sites stable and accessible for decades. Families can visit well-maintained gravesites, and cemeteries maintain their appearance and safety.
When Is an Urn Vault Mandatory?
Most U.S. cemeteries require some form of outer burial container for ground burial of cremation urns. Requirements vary, so always check with your specific cemetery before purchasing.
Some cemeteries accept polymer vaults, while others insist on concrete vaults from approved suppliers. A few allow durable urns made of cultured marble, cast bronze, or stone without separate vaults - but only if they meet strict compression testing standards.
State regulations generally let individual cemeteries set policies, though burial permits often specify vault requirements. Your plot contract will typically spell out vault mandates.
From the cemetery's perspective, vault requirements protect them from future costs and liability issues. It's easier to prevent problems with proper vaults than deal with sunken graves and equipment damage later.
Choosing the Right Urn Vault for Ground Burial
When selecting an urn vault for ground burial, understand your material options and what each brings to the table.
Polymer vaults have become the go-to choice for most families. These high-impact plastic containers are lightweight at 8.2 pounds, yet incredibly strong - often rated at 1000 PSI or higher. They're budget-friendly, typically $49.95 to $200, and most cemeteries accept them.
Concrete vaults represent the traditional standard many cemeteries have relied on for decades. They're built to last but are heavy - often over 100 pounds - requiring more labor and equipment for installation. They also cost more than polymer options.
Steel vaults offer excellent durability with various grades available. Basic steel provides solid protection, while stainless steel offers maximum corrosion resistance. These typically range $300-$600+ with longer warranty periods.
Cultured marble vaults bring beauty and strength. Available in over 40 colors, they can serve as both urn and vault in one package, eliminating separate components while creating personalized memorials.
Bronze and copper vaults offer maximum durability and prestige at $1,000+.
Lined vaults include additional moisture barriers - usually bronze, copper, stainless steel, or high-impact plastic inside the main shell for extra protection.
Single vaults accommodate one adult cremation urn, while companion vaults hold two urns for couples.
Advantages & Disadvantages of Materials for Urn Vaults for Ground Burial
Polymer vaults excel in several areas. Their lightweight design makes installation easy - often requiring simple auger holes rather than full excavation. They're cost-effective and offer excellent strength-to-weight ratios. Most cemeteries accept them without question.
Drawbacks include some traditional cemeteries specifically requiring concrete, and families preferring premium appearance. There's also long-term environmental consideration of non-biodegradable plastics.
Concrete vaults offer traditional cemetery standards trusted for generations. They're extremely durable and widely accepted, available with various lining options.
However, their weight creates installation challenges requiring more labor, specialized equipment, and careful handling. They cost more upfront and require square hole preparation rather than simple auger drilling.
Steel and metal options provide premium durability lasting generations. Stainless steel offers excellent corrosion resistance with extended warranties and professional appearance.
Trade-offs include higher costs and weight considerations during installation.
Combination Urn-Vaults: 2-in-1 Solutions
Some urns are built tough enough to serve as their own vault. These combination urn-vaults eliminate separate burial containers, potentially saving money while creating personalized memorials.
Cultured marble urns lead this category. The Mackenzie Cultured Marble Urn Vault, available in over 40 colors, doubles as both urn and vault while meeting compression standards.
Cast bronze urns offer another vault-free path. Their inherent strength and corrosion resistance make them suitable for direct burial in many cemeteries.
Stone urns from granite, marble, or natural stone can also meet compression standards for vault-free burial, offering timeless, natural appearance.
The key requirement is that combination units must pass compression testing to handle soil pressure and equipment loads without collapsing. Always verify with your cemetery that they accept vault-free burial for durable urns - policies vary significantly.
Meeting Cemetery Requirements: Regulations, Sizing & Installation
Understanding cemetery regulations before purchasing an urn vault for ground burial prevents headaches and unexpected costs. While most cemeteries follow similar standards, each facility has specific requirements.
Most urn vaults follow standard dimensions: 15" L × 15" W × 18" H, with low-profile models at 14" H for tighter space restrictions. These work well with most adult cremation urns while fitting cemetery plot layouts.
Expect cemeteries to require 18-24 inches of soil cover above the vault. Some have dedicated cremation sections with different depth rules than traditional casket areas.
Many cylindrical vaults can be installed using auger drilling, requiring only a 14-inch diameter hole. This is faster and cleaner than square hole excavation that traditional rectangular concrete vaults need.
How to Measure & Match Your Urn to a Vault
Getting sizing right prevents problems when your urn doesn't fit the purchased vault. Start by measuring your urn's actual dimensions - length, width, and height - including decorative elements.
While standard adult cremation urns need 200-220 cubic inches of capacity, vault selection depends on the urn's external size, not internal volume. Decorative urns might have right capacity but unusual proportions affecting vault fit.
Companion vaults require extra consideration. You're fitting two urns and need to consider positioning - side by side or vertically stacked affects required vault dimensions.
Pay attention to interior dome height. Some vaults offer 9 inches of interior clearance for taller decorative urns, while standard models provide 6.5 inches.
Step-by-Step Installation Guide for an Urn Vault for Ground Burial
While professional installation ensures cemetery standards compliance, understanding the process helps coordination.
Grave opening starts the process. Cylindrical vaults need precise 14+ inch diameter holes. Traditional rectangular vaults need square excavation with clean sides.
Site preparation involves leveling and clearing debris. In rocky conditions, crews add sand or gravel for stable, level foundations.
Vault lowering varies by weight. Lightweight polymer vaults often go in by hand, while heavier vaults require mechanical equipment.
Cremation urn placement follows, sometimes with padding to prevent shifting when the lid goes on.
Sealing the vault involves tongue-and-groove fitting, butyl tape seals, or adhesive applications, determining long-term moisture protection.
Backfilling requires gradual soil replacement with hand-tamping to prevent settling. Final grading should match surrounding cemetery levels.
Cemetery records are updated with vault specifications, installation date, and special considerations.
