Reinforcing the RECESS Ceiling

The steel roofing material (B Formlock from Con-Dek) required wooden under-bracing to ensure that it would not collapse during the initial concrete pour and set-up. This pour would produce a 4" roof, which on it's own was inadequate for my needs. The final deck pour would add an additional 6" of concrete reinforcement, with a layer of foam insulation and waterproofing between them.
