Abstract
A mold core with a plurality of tension springs is placed in a mold box such that the top of the mold core is even with the top of the mold box when the plurality of tension springs have no tension. Block mix including a substantial amount of compressible material is poured into the mold and lightly vibrated. A movable bottom plate then moves downward at the same time as the mold core is moved downward a first distance to stretch the plurality of tension springs. After the mold core is moved downward the first distance, the movement of the mold core stops while the movement of the movable plate continues downward, thereby ejecting the partial block element from the mold. Block elements are cured, then glued together to form a complete block. One or both of the exterior surfaces of the block may have a wooden attachment layer attached.
