Rebar was placed in the butterfly notches, which were then grouted with waterproof, expanding grout to bind the panels into a single solid structure.
The two openings eventually provided access into the upstairs bedrooms over the garage, and the downstairs spa room.
Bolted together at the corners, they all came together into an extremely solid structure. Here the positioning of the pentagons, hexagons and half hexes can be seen. Special butterfly style edge connectors tie the entire structure together into a single unified whole. These connections were designed by Hait to stitch the pieces together using steel rebar and fiber reinforced grout to form a solid connection.
