Conventionally Cast Concrete

Conventionally cast concrete structures are built with re-usable aluminum or plywood forms to form walls and foundations.

The process is very quick, as all walls can be poured at the same time, with door and window openings cast at the time the walls are poured. Steel reinforcing bar is typically used to strengthen the wall. Some systems even use cast-in-place floors and ceilings. These saferooms may be built in existing homes, new homes or as stand-alone rooms.

Basic saferoom design with concrete blocks, traditionally cast concrete, and for 4- and 6-inch flat ICF walls and 6-inch waffle grid ICF walls may be found in the FEMA publication Taking Shelter From the Storm: Building A Safe Room Inside Your House, which includes construction plans, materials, and construction cost estimates.

It's available from FEMA at no charge by calling toll free (800) 480-2520.
