Patent ID: 8153046

Claim:
A method of forming a wall, consisting of the steps of: a) assembling a plurality of wall forming modular units to create a free standing structure, wherein each modular unit consists of a first lattice framework panel having a plurality of openings therethrough, a second solid panel, and a plurality of connecting members securing said first panel to said second panel in a spaced, parallel relationship such that a cavity is formed between said first and second panels for receiving flowable concrete therein; b) introducing said flowable concrete into said cavity, wherein said flowable concrete fills said cavity and extends through said openings through said first panel such that said flowable concrete extends beyond an external surface of said first panel; c) troweling said flowable concrete that extends beyond said external surface of said first panel to form an exterior surface layer; and d) allowing said flowable concrete to set, wherein said first panel, said connecting members, and said flowable concrete become a substantially monolithic structure when said flowable concrete is set.
