It's meant to provide structural support to the soil above a casket and to help prevent the ground from sinking or collapsing over time.
The use of grave liners is a common practice in many Cemeteries because they contribute to the long-term preservation of the Gravesite and help maintain the overall appearance of the cemetery grounds.
Though similar in concept, grave liners are distinct from Burial Vaults. Grave liners provide basic protection for a casket, but burial vaults offer enhanced protection and sealing capabilities, helping to prevent moisture, soil, and other elements from entering a casket.
Vaults are typically more robust and may include additional features such as a sealed top, decorative finishes, or interior linings.
Additional key points about grave liners include:
Construction: Grave liners are typically made of concrete, plastic, fiberglass, or other durable materials. They are usually rectangular or box-shaped, with an open bottom and a tightly sealed or latched top.
Placement: A grave liner is placed in the ground before a casket is lowered into a grave. It sits inside the prepared burial hole and surrounds the casket, effectively creating a protective barrier between the casket and the surrounding earth.
Regulatory Requirements: In some cemeteries and regions, the use of grave liners is mandated by local regulations or cemetery rules. These requirements are intended to ensure the long-term stability and maintenance of the cemetery grounds.
Options: There are different types of grave liners available, including basic concrete liners and more elaborate vaults that may have sealed tops and additional protective features. The choice of liner often depends on personal preference and budget.
