Tunnel Modules

Precast concrete tunnel modules for underground access between structures, hidden rifle ranges, shelter rooms, and safe rooms.

Superior Precast tunnel modules provide secure underground access between structures, concealed shooting ranges, and protected shelter or safe rooms. Modular precast sections are manufactured at our plant and assembled on site... allowing tunnel systems of virtually any length and configuration.

Tunnel modules are engineered for underground installation with watertight joints between sections to prevent water infiltration. Interior dimensions, entry points, and overall layout are configurable to match your specific application... whether that's a walkway between buildings, a below-grade rifle range, or a residential safe room.
