Radius Engineering International - C-60

The C-60 is an American-made underground bunker constructed entirely from high-grade fiberglass. Radius Engineering International chose this material because it prevents the rust and corrosion common in steel underground shelters.

The C-60 is an underground disaster bunker designed to sustain dozens of occupants. Its size and fiberglass construction make it one of the larger community-oriented models offered by Radius Engineering International.

Radius Engineering International uses fiberglass because it creates an impermeable underground structure that will not rust or degrade over time. This ensures the C-60 remains structurally sound and watertight for decades while buried underground.

The C-60 and other disaster bunkers designed by Radius Engineering International are American-made. They are manufactured in the United States to strict engineering standards before being buried underground.
