Crack-Pac® Injection Epoxy

Epoxy Injection

This product's information may differ depending on the category of use. You are currently viewing details related to Epoxy Injection. You can also view product information related to the category: Restoration Products

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

  • Pressure injection
  • Gravity feed
  • Underwater pressure injection


  • 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)

Shelf Life

  • 24 months from date of manufacture, unopened


  • Suitable 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.
  • In order for components to mix properly, the resin and hardener must be conditioned to 60°F (16°C) to 80°F (27°C) before mixing.

Clean Up

Wipe up with cotton cloths. If desired scrub area with abrasive, water-based cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), laquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material — Chip or grind off surface.
