Metal vs Concrete Outer Burial Containers

Concrete outer burial containers are the most widely used type in the industry because of their availability and lower unit cost. They provide ground stability and basic casket protection through sheer mass. However, concrete is porous. Over time, moisture migrates through the walls and lid, and the joint between the lid and base is sealed by gravity and weight rather than by an engineered seal system.

Metal outer burial containers address both of those limitations. Steel and alloy walls are nonporous, and air-seal dome construction provides a mechanical moisture barrier at the lid joint. CMV Fabrication's metal OBCs deliver both structural ground support and active moisture resistance in a single unit. For funeral homes presenting outer burial container options to families, the metal OBC represents a measurable step up in protection from the concrete baseline.
