A prefabricated construction for building walls, comprising a pair of panel elements each having a wall portion and a plurality of stiffening rib portions extending along the wall portion. At least some of the rib portions on each panel element include recesses on edges thereof which are spaced from the wall portions. The pair of panel elements face each other with substantial juxtaposition between the rib portions of one of the pairs of elements with those of the other of the pair of elements, and with the wall portions spaced from each other. The space between the wall portions and juxtaposed rib portions are substantially filled with expanded synthetic material to form a wall element and conduit passages are defined in the synthetic material between the pair of panel elements and adjacent the recesses in the rib portions.

A prefabricated construction for building walls, comprising: a pair of substantially flat, rectangular, cement wall elements; a plurality of integral, spaced, transverse, stiffening rib portions extending from one surface of each of said elements; a plurality of integral, spaced, longitudinal stiffening rib portions intersecting said transverse stiffening rib portions and extending from the same surface of each of said elements, at least some of said transverse rib portions on at least one of said wall elements including recesses on edges thereof away from said one surface, at least one of said recesses in one of said transverse rib portions being aligned with one of said recesses in each of a plurality of said transverse rib portions, and the depth of said recesses being less than the height of the respective transverse rear portions, said wall elements facing and spaced from each other with said stiffening rib portions of one wall element facing said stiffening rib portions of the other of said wall elements, and at least some of said stiffening rib portions of one wall element aligned with at least some of said stiffening rib portions of the other of said wall elements; and expanded synthetic material substantially filling the space between the said wall elements with at leaast one conduit passage defined in said expanded synthetic material adjacent at least some of said aligned recess of said transverse rib portions.
