ARDEX Concrete Crack Lock is a carbon-fibre crack-bridging stitch engineered for structural concrete repair and reinforcement. When installed with ARDEX RA Epoxy Paste (RA 88, RA 142, or RA 144), each lock permanently stabilises and bonds both sides of a crack, forming a durable composite that restores tensile strength and prevents further propagation.

Each pack contains 20 pre-cut carbon-fibre locks ready for installation. Once the slot and holes are prepared and filled with epoxy paste, the locks are inserted to restore structural integrity with minimal surface impact.

Ideal for repairing slabs, foundations, walls, and industrial flooring, the Crack Lock System provides long-term durability and full compatibility with ARDEX epoxy repair products.
