Simpson CRACK-PAC Injection Epoxy Kit by Simpson Strong-Tie is engineered to structurally repair cracks in concrete ranging from 1/64-in. to 1/4-in. wide in walls, floors, slabs, columns, and beams. The mixed adhesive has the viscosity of a light oil and a low surface tension, allowing it to penetrate fine to medium-width cracks in dry, damp, or wet conditions with excellent results. Resin is contained in the cartridge and hardener is contained in the nozzle, keeping preparation clean and straightforward from start to finish.

Key Features

• Dispenses with a standard caulking tool - no special dispensing equipment required, so you can get to work immediately without additional tool investment.
• Clean and easy to mix - the self-contained cartridge-and-nozzle design simplifies mixing and reduces mess, saving time on the job.
• Seals out moisture - protects embedded rebar from corrosion and shields flooring from moisture intrusion, helping extend the service life of the repaired structure.
• Chemically bonds with concrete to restore strength - the epoxy becomes part of the concrete itself, returning structural integrity rather than just filling the surface.
• Non-shrink formula resistant to oils, salts, and mild chemicals - the cured repair holds its shape and stands up to harsh environmental exposure without degrading.
• Meets AASHTO M-235 and ASTM C881, Type I, Grade 1, Class C requirements - compliance with recognized industry standards gives contractors and engineers confidence in the repair's performance and suitability for regulated projects.
• Freeze-thaw resistant - the cured epoxy withstands repeated freeze-thaw cycles, making it a reliable choice for exterior and below-grade concrete repairs in cold climates.

Why This Product

• A complete repair system in one kit - each kit includes cartridge/nozzle sets, E-Z-Click injection ports, injection fittings with tubing, paste-over epoxy, applicators, and gloves, giving you everything needed to complete a professional concrete crack repair without sourcing additional components separately.
• Works in conditions other products cannot - the low-viscosity, light-oil consistency allows this injection epoxy to penetrate fine to medium-width cracks even in damp or wet concrete, making it practical for real-world job site conditions where surfaces are rarely perfectly dry.
• Dual-purpose protection - beyond simply filling a crack, this epoxy seals out moisture to prevent rebar corrosion and floor damage while chemically bonding with the concrete to restore load-bearing strength, addressing both structural and long-term durability concerns in a single application.
• No special tools or complicated setup - compatibility with a standard caulking gun means crews already have the equipment on hand, reducing downtime and making this kit a practical choice for concrete crack repair on walls, floors, slabs, columns, and beams alike.
