Abstract: A wall system having high vertical and lateral stability as well as vertical loading capacity is disclosed. The wall system includes blocks formed from two opposing plates. The plates have a spacer holding the plates at a predetermined distance from one another. Each plate includes tongues and grooves for fitting together with adjacent blocks in the wall system when the blocks are stacked with one another. Once the blocks are stacked, the space between the opposing plates of the blocks is filled with an spray insulation to lock the blocks in place.
