Abstract
The present concrete crack repair device (CCRD) can be comprised of two nodules connected by an elongated strip wherein the elongated strip can be narrower than the nodules in at least one plane. Both the elongated strip and the nodules can comprise carbon fibers wherein most of the carbon fibers are located within the same plane maximizing the tensile strength of the device. Installation of the CCRD can be performed by drilling holes into the surface of the concrete on either side of the crack and cutting a slot in the surface of the concrete between the two holes, or adding the holes after the slot has been cut, wherein the slot and holes are located in a line that is roughly perpendicular to the crack. The CCRD can then be installed by placing each nodule in a hole and the elongated strip within the slot.
