HexaBlock™ is a revolutionary lift and insert snap together building block REPLACING 2x4’s, PLYWOOD, AND INSULATION. 3-triangle fasteners lock together two hexagons (and 2-derivative halves) into layers that “predictably” distribute forces in three directions. A single computer formula can then rapidly analyze HexaBlock assembly-designs, converting non-technical “ideas” into engineered structures equal to those of aircraft engineering. HexaBlock can be decorated just like conventional buildings with siding, sheetrock, flooring, etc. Validate engineering at the same relative ease that HexaBlocks snap together.
