Product Name: Concrete Crack Lock®
The Concrete Crack Lock® (CCL) is a patent pending revolutionary new product that was developed to improve concrete crack bridging, stitching
repair. The CCL is installed by making a single blades 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 High Strength Anchoring Epoxy Paste and the CCL is inserted. 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.
03: WHERE TO USE:
The Concrete Crack Lock™ has been engineered to stop cracks in concrete slabs, poured walls, masonry, concrete block foundations,
columns, industrial buildings, bridges, and foundations. The Concrete Crack Lock™ system is designed for cracks of various sizes under
virtually any circumstance. It can also be used to increase seismic strength to repairs after an earthquake.

06: LAYOUT: SURFACE PREP
The surface of the concrete must be clean and free of loose debris. Lay out the individual crack locks by marking the crack every 8” to 12”. Then trace the
crack locks at each location and orient them at roughly 90 degrees to the crack (a simple template may also be used). Vary the angle at each location
slightly to reinforce the crack from moving in all directions.
Once the layout is complete, make the cuts across the crack using a .08 (2mm) thick cutting wheel and ensure that you are cutting to a minimum depth
of 5/8” (16mm) for the entire length. This will allow sufficient epoxy cover over the CCL’s. Once the cuts are made, drill 1/2″ (13mm) diameter holes at
the appropriate locations on the ends of the cuts to accept the CCL.
Hint: Once one end is drilled, re-check the spacing prior to drilling the second end. Also, 5/8″ (16mm) diameter holes may be drilled to help ensure
proper fit even with a slight misalignment but this will use slightly more epoxy.
Clean all loose debris from the preparation and fill with High Strength Anchoring Epoxy Paste. Once the preparation is filled with epoxy, work the
CCL into the preparation, ensuring that all voids around it are filled. Scrape any excess epoxy off of the surface. This material can be worked into the
crack between the CCL. The crack needs to be filled by this method or by injection to stop any movement between the opposite sides of the crack.
08: TOOLING & FINISHING
Any tool that will accept a diamond saw blade suitable for cutting concrete will work to make the cuts across the crack. A tuck point grinder or
slotting tool with dust shroud works best to minimize dust while allowing you to set the depth of the cut. Use any hammer drill with a ½” (13mm)
diameter masonry drill bit to drill the holes. Larger bits can be used but will require additional epoxy to fill the larger holes.
