Materials Used In Burial Vault Construction:
Concrete
Plastic
Metals
Why Concrete?
* Minimum compressive strength of 5,000lbs per square inch.
* Loves moisture
* Continues to cure and gain strength underground
Why Plastic?
* Tensile strength of 3,500 to 4,500 lbs per square inch.
* Tensile strength is the ability to stretch
* Permeability - Impervious to water
* Durability - Highly durable in a sub-soil environment
Types Of Plastics Used:
* Strentex - a high impact and high tensile strength
* ABS (Acrylonitrile Butadiene Styrene)
* 400% higher impact strength
* 50% higher tensile strength
* Same plastic used in telephone casings, refrigerator freezers and Football Helmets
Why Metals?
* Tensile Strength - 35,000 to 75,000 lbs per square inch
* Permeability - Impervious to water
* Durability - Moderate to high durability in a sub-soil environment
Types Of Metals Used:
* Stainless Steel - Tensile strength of 75,000 lbs per square inch
* Copper - Tensile strength of 35,000 lbs per square inch
* Bronze - Tensile strength of 40,000lbs per square inch
Unidex Structural Adhesive:
* Especially formulated, in a two part mixture. Unidex offsets the weakness of concrete by
chemically bonding the plastic & metals to the concrete.

Why do you need a burial receptacle?
An outer burial containers are required by most all cemeteries to preserve the
beauty and to help reduce the maintenance cost by supporting the weight of the
ground and equipment that pass over the grave.
How to choose a burial receptacle:
An outer burial container is defined as a burial receptacle placed in the ground, in
either a sectional, dome or box form, that helps support the weight of the earth to
prevent the grave from collapsing. An concrete burial vault is defined as a lined
and sealed concrete burial receptacle which performs all the functions of a grave
liner, but in addition, it is constructed using lining and sealing materials to
increase the overall tensile strength and to reduce or eliminate the intrusion
of exterior elements.
(National Concrete Burial Vault Association)
There are three basic types of burial receptacles:
The dome container, the grave box and the reinforced burial vaults. The dome
container, a lightweight product commonly made of fiberglass or plastic, is
designed to be stacked and stored above ground for a long period of time before
burial.
The grave box, an unlined concrete box with drain holes, allows ground water to
escape.
For the most protection you'll want to consider a high-strength concrete reinforced
burial vault. This receptacle is long-lasting, with a coated exterior and a
reinforced interior.
