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.
