Sikadur® Crack Fix is a 2-component, 100% solids, moisture-tolerant, low-viscosity, high-strength, multi-purpose, epoxy resin adhesive. It conforms to the current ASTM C-881 and AASHTO M-235 specifications.

Where to use

  • Gravity-feed of cracks in horizontal concrete and masonry.
  • Low pressure injection of cracks in structural concrete, masonry, wood, etc.
  • Grouting bolts, dowels, pins, etc. into horizontal concrete surfaces.

Advantages

  • Formulation identical to popular, high strength adhesive Sikadur® 35, Hi-Mod LV.
  • Five times stronger than concrete.
  • Convenient easy to use, single tube cartridge - fits standard caulk guns.
  • Deep, penetrating and tenacious bonding of cracks in structural concrete.
  • No mess - self-mixing.

Preparation:

Mixing

Cartridge Set-Up: Remove twist-cap and port plug from top of cartridge. Press one of enclosed “flow restrictors into opening. Insert one of the enclosed static mixers through twist-cap and attach to threading. Insert Sikadur® Crack Fix cartridge into good quality caulking gun. Point upward during initial squeeze of gun trigger to purge any entrapped air. As mixed resin approaches end of mixer, discard rest of initial squeeze and portion of next squeeze to ensure uniform blend of adhesive components.

Application

To gravity feed cracks - Blow vee-notched crack clean with oil-free compressed air. Dispense Sikadur® Crack Fix slowly into vee-notched crack. Continue placement until completely filled. Seal underside of slab prior to filling if cracks reflect through. To inject cracks - Set appropriate injection ports. Seal ports and surface of crack with Sikadur® 31, Hi-Mod Gel or Sikadur® 33. When the epoxy adhesive seal has cured, inject Sikadur® Crack Fix with slow steady pressure. Consult Technical Service for additional information.

Coverage:

1 cartridge yields approximately 10.7-11.0 cu. in. (175-180 ml) of usable epoxy resin.
