A grave liner is typically made of which material?

• A. Wood.
• B. Concrete.
• C. Metal.
• D. Plastic.

Answer: (B)

In burial practice, the grave liner serves to provide structural support for the grave and help prevent soil from caving in around the casket. It is typically made of concrete because concrete offers the right combination of strength, durability, and cost-effectiveness. It resists moisture and soil pressure over many years and can be manufactured in standardized shapes to fit graves securely. Wood would rot and weaken the structure over time, metal can be expensive and prone to corrosion, and plastic generally doesn’t provide the rigidity and long-term stability needed for a liner. So concrete is the standard material used for grave liners.
