Structural Reinforcement with Carbon Fiber Staples - (optional)

Installing Carbon Fiber staples before injecting a crack with epoxy or foam will add structural integrity to your repair. The carbon fiber (graphite) material of these staples provides 40,000 pounds of tensile strength (equivalent to #4 rebar). When spaced along the crack at 18 - 24" intervals they effectively spread the crack causing loads beyond the glue line. Since the staple is flat it can be mounted with minimal concrete removal. Since the carbon does not corrode as steel will, it will not be prone to future discoloration or deterioration of the repair.
1. Mark staple location.  Staples should be positioned every 18 - 24" along the length of the crack. 2. Using 1-1/8" bit, core-drill holes through plaster into concrete where prongs of staple will set. 3. Score 1/4" to 1/2" into plaster  to create outline for staple bed.
4. Use chipping hammer to chip away plaster to create staple bed. 5. Fill holes and base of staple bed with Staple Epoxy. 6.  Imbed and cover staple in epoxy then smooth to a level below plaster surface.  After epoxy has cured proceed with crack injection steps.
