<p>This modular building wall unit comprises a hard foam layer and a concrete layer intimately bonded to each other along an interface between the layers. A reinforcing wire mesh matt is embedded in the hard foam layer and reaches with anchoring elements into the concrete layer which may also have embedded therein a further wire mesh matt. The present units are cast in a mold by first keeping the mold horizontally and filling it partially with the hard foam. When the hard foam is sufficiently cured, the mold is brought into a substantially upright position, closed and filled with the concrete mix. Of course, a top portion is left open for the filling.</p> |
