Abstract:

An improved wall system comprising a plurality of blocks formed at least partially of a masonry material, a layer of an insulative material, and a layer of a curable or settable material interposed between the blocks and the layer of insulative material. The blocks may provide the wall with a masonry external surface or an exterior surface that is substantially aesthetically completed upon arrangement of the blocks and prior to the pouring of the layer of curable or settable material. In an alternate embodiment, ties may extend between a pair of blocks to form a construction unit that can be assembled in a factory or other location and then transported to a work site. The construction unit may be configured to include a space between spaced apart blocks into which a layer of an insulative material and a layer of a curable or settable material may be received.
