Drill a 10mm hole for the 6.0mm tie using a rotary percussion drill. The hole should be 25mm from the end of any brick and on its horizontal centre line and penetrate 55mm into the far leaf. Thoroughly clean the holes in the near and far leaf using a hand pump to blow out debris. Using a resin nozzle extension inject Target Fixings Polyester Resin across the cavity and into the far leaf hole until it is full. Insert the Resi Flex tie through the near leaf hole and into the far leaf hole allowing it to rotate as it is installed. After leaving to gel for about 20 minutes the holding capability can be checked using a Target Fixings Load Test Unit. As a general rule a proof test load of about 1kN in tension is an adequate bond. After an acceptable proof test is performed the near leaf connection is made using Target Fixings Polyester Resin. The brick may then be colour matched for a near invisible finish.
