What is the name of the method in burial vaults that uses both an air seal and an epoxy for sealing?

The method that utilizes both an air seal and an epoxy for sealing burial vaults is known as the double seal. This approach enhances the protective qualities of the vault by providing an additional layer of security against water infiltration and environmental elements. The air seal works by creating a barrier that prevents air (and moisture) from entering the vault, while the epoxy further seals the joint areas to ensure a tight seal.

Using a double seal is especially important in regions with high water tables or where soil conditions may otherwise compromise the integrity of the burial vault. This method ensures that the casket remains protected and helps to maintain its condition over time. The combination of these two sealing mechanisms minimizes the risk of decay, thereby upholding the dignified presentation of the remains and the overall condition of the vault.

In the context of burial vaults, this reliable sealing method underscores both practical functionality and the emotional value placed on preserving the deceased's resting place.
