Abstract: A method for fastening cementitious components together or for fastening a cementitious component to a non-cementitious component to form a structure. In a preferred embodiment, the apparatus is a screw having a hollow shaft from which threads protrude and a tip comprising a plurality of drilling teeth or a plurality of thread members that surround said central space, each of said thread members forming a two-dimensional spiral. In use, the invention is operated by screwing it into the cementitious components and then injecting an adhesive into the void created by the screwing step.

Abstract: Cementitious construction system that employs beams with utility voids, special screws coordinated with AAC anchoring inserts, and interlocking fastening systems that make possible a precast building requiring no welding and having all the structural advantages of a poured in place structure but which is constructed in less time and cost than existing precast systems.

Abstract: A cementitious building having a predetermined measured grid system using structural trim members for doors and windows that are sized so that when installed in openings no further trim is necessary.

Abstract: Processes, machines, articles of manufacture and compositions of matter required to construct a habitable structure comprised of a cementitious product, preferably autoclaved aerated concrete (“AAC”), formed in unique blocks, panels and beams. This results in an extremely environmentally friendly habitable dwelling, residential or commercial, which, due to the resultant synergy of embodiments, when compared to a similar structure employing prior art and/or current industry's standard materials and methods of construction, is structurally superior and simultaneously yields substantial savings in labor, time and costs.

Abstract: A roof panel, roof or structure comprising a roof panel body having an edge comprising a fascia water deflection system, said fascia water deflection system comprising a chamfer having at least one sharply angled ridge. In some embodiments, said roof panel body is provided with a trough adjacent to said edge, so that when said roof panel body is installed on a structure, said trough runs at a downward angle and water entering said trough flows by force of gravity through said trough. In other embodiments, the roof panel body is coated with a waterproof roofing material.
