ABSTRACT:
An internal metal stitching method for repairing cracks in concrete comprising the steps of cutting slots to facilitate metal stitching brackets installed in saw cuts every two feet and at alternating angles to the crack. The concrete is marked using a stitching bracket as a template for marking out the concrete saw cuts. The saw cuts are made in the concrete following the outline of the bracket. The first cut is made along the length of the large bracket and the second and third cuts are made near the ends of each large bracket to accommodate end brackets which when fitted resemble a double "t". The saw cuts are cleaned and dried, filled with a filler resin, and the metal brackets are inserted and are submerged to 1/4" below the concrete surface. The filler is smoothed out to a level flush with the concrete surface. Additional decorative surfaces may then be applied, such as ceramic tiles, carpeting, linoleum or paint. Various shaped metal stitching brackets and a bracket made of filler are also disclosed.
