ABSTRACT:
A building structure and method of making the same are disclosed wherein an inflatable form is inflated and an insulation layer of urethane form is applied to the undersurface of the foam. Hanger members are secured to the foam layer by adhesively affixing planar base portions of the hangers to the foam layer whereafter additional foam is applied to embed the hanger bases. Reinforcing mesh is secured to and supported by the hangers followed by the application of one or more layers of a cementitious material which is allowed to cure. Air pressure beneath the form is progressively increased to maintain a substantially constant uplift force on the foam. The inflatable form may be removed after curing and a protective coating applied to the outer exposed surface of urethane foam to protect it from ultraviolet degradation.
