Safe Room Design with the Block Joist® System

Acknowledged as the most practical way to build a Safe Room, the NCMA publication states "forming for the cast-in-place roof is averted and the entire wall and roof structure are grouted in the same operation at the same time. Having to provide both a grout mix (for the walls) and a concrete mix (for the roof) is not necessary, saving construction, labor and equipment time."
