Crack-Pac® Injection Epoxy - Ace Building Materials

Crack-Pac® Injection Epoxy

Crack-Pac injection epoxy is designed to repair cracks in concrete ranging from 1/64" to 1/4" wide in concrete 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.  
Key Features
  • Dispenses with a standard caulking tool, no special dispensing tool needed
  • Clean and easy to mix
  • Seals out moisture, protecting rebar in the concrete from corrosion and flooring from moisture damage
  • Chemically bonds with the concrete to restore strength
  • Non-shrink material resistant to oils, salts and mild chemicals
  • Meets the requirements of AASHTO M-235 and ASTM C881, Type I, Grade 1, Class C
  • Freeze-thaw resistant
Applications
  • Pressure injection
  • Gravity feed
  • Underwater pressure injection
Color
  • Resin — dark purple, hardener — clear/amber, mixed: light amber. The color of epoxy will change from amber to dark purple during the cure process and then fade back to light amber within a few weeks of installation.
Storage Conditions
  • For best results, store between 45°F (7°C) and 90°F (32°C)

Usage Temperature

  • 60°F (16°C) to 90°F (32°C)
