RHINO CARBON FIBER CONCRETE CRACK LOCK (CCL) is a revolutionary crack bridging system developed to improve concrete crack repair. The CCL is installed by making a single blade-width cut across the crack and drilling two holes along the cut at the appropriate locations. Once the preparation is complete and free of dust, it is filled with DUNLOP BUILDER’S BOND and the CCL is inserted and covered with DUNLOP BUILDERS BOND. Once installed, the CCL permanently bonds both sides of the crack together. Due to the unique shape of the CCL and the preparation in the concrete, the tensile strength of the carbon fiber is relied upon as well as the epoxy bond strength along its length.
