  • Patent number: 5839251
    Abstract: A masonry construction aid that enables novice and professional masons to easily construct a masonry structure such as a sidewalk, patio, driveway or vertical wall. The aid allows its user to insert masonry into a pre-determined, pre-formed, soluble pattern that contains within it a bonding material. After applying a catalyst such as water to the pattern, the pattern will disintegrate, the bonding agent will activate and bond the masonry together and harden into a permanent structure. This will result in a masonry structure that does not require any special skills to construct. The user will not be required to prepare or apply mortar, or manually align the masonry.
