The Crack-Pac® two-part, high solids, low-viscosity crack injection epoxy is designed to repair cracks in concrete. The mixed adhesive has the viscosity of a light oil and a low surface tension that enables it to penetrate fine to medium width cracks. Resin is contained in the cartridge and hardener is contained in the nozzle. Once the nozzle is threaded onto the cartridge, the hardener is released into the resin-filled cartridge by turning the knob at the base of the nozzle. The two components are mixed by shaking the cartridge.
Crack-Pac® injection epoxy is also available in the Crack-Pac Injection Kit. The kit includes everything needed to pressure inject approximately 8 lineal feet of cracks: - 2 Crack-Pac cartridge / nozzle sets
- 12 E-Z-Click Injection Ports
- 2 E-Z-Click Injection Fittings with 12" tubing
- 1 pint of paste-over epoxy (8 oz. of resin + 8 oz. of hardener)
- 4 disposable wood paste-over applicators
- 1 pair latex gloves
- Installation video
FEATURES - Dispenses with a standard caulking tool, no dedicated dispensing tool needed
- Low viscosity
- Clean and easy mixing; no additional tools required
- Chemically bonds with the concrete to restore strength
- Resistant to oils, salts and mild chemicals
- Non-shrink
- Conforms to of ASTM C-881 Type I & II, Grade 1, Classes B & C
APPLICATIONSuitable for repair of cracks ranging from 1/64" to 1/4" wide in concrete walls, floors, slabs, columns and beams. Can be used to inject cracks in dry, damp or wet conditions with excellent results. Not for use in actively leaking cracks. Apply to concrete 40°F or above.
