Composite foam and concrete foundation, composite foam and concrete wall and method of mounting composite foam and cement wall to the foundation

A method of constructing a composite foam and concrete wall, the method comprising:

• positioning a plurality of foam panels proximate each other to form a foam layer of a selected height and width;
• forming a plurality of spaced apart channels in the foam layer extending from proximate a bottom end to proximate a top end;
• positioning rebar within the spaced apart channels;
• positioning a form about a perimeter of the foam layer wherein the form extends above an upper edge of the foam layer a selected distance;
• and
• placing concrete on the foam panel and within the form to form a concrete layer with a plurality of pilasters extending into the foam layer and within the plurality of spaced apart channels.

A composite foam and concrete wall comprising;

• a foam layer having a top surface, a bottom surface, a left wall surface and a right wall surface wherein the foam layer comprises at least two foam panels that define a seam that is substantially parallel to the top surface and the bottom surface;
• a form secured to a top surface of the foam layer and extending from a perimeter of the foam layer;
• and
• a concrete layer placed onto a surface of the foam layer wherein the form is retained to the foam layer and provides a finished surface to the concrete layer.
