Technical and product guidance for the item you’re viewing.
  • Mechanical injection points for compatible resin injection
  • Multiple diameters and lengths for packer selection
  • Mechanical seal within a correctly prepared drill hole
  • Suitable for concrete and masonry injection work
  • 1. Identify and map the crack, joint or water ingress pathway.
  • 2. Drill injection holes at the specified angle, spacing and depth to intercept the target pathway.
  • 3. Clean drill holes thoroughly.
  • 4. Insert the selected mechanical packer.
  • 5. Tighten sufficiently to achieve a secure mechanical seal without damaging the substrate.
  • 6. Connect a compatible injection pump coupler.
  • 7. Inject the nominated resin under controlled pressure.
  • 8. Monitor adjacent packers and surrounding substrate for resin travel, leakage or distress.
  • 9. Progress sequentially through the injection points.
  • 10. Remove packers after curing where required.
  • 11. Reinstate injection holes using a suitable repair material.
  • Determine drilling angle, spacing, depth and injection pressure from the substrate condition, crack geometry and injection system. Follow the selected resin manufacturer's application and curing instructions.

Crack Injection Packer FAQs

What are Crack Injection Packers used for?
They provide mechanical injection points for pressure injection of compatible PU resins and other approved injection materials into cracks, joints and voids in concrete and masonry.
Which sizes and pack quantities are available?
All four physical sizes are available singly. The 10mm diameter sizes are also available in 100 Packs, and the 13mm × 70mm size is also available in a 50 Pack. Select Size, then Pack, using the product options.
How do I select a packer size?
Select packer diameter and length to suit substrate thickness, drilling depth, crack or joint geometry, injection angle, resin type and the required injection depth and pressure. Longer packers may suit deeper installation where the drilling geometry requires it; packer length alone does not determine crack interception. Confirm compatibility with the pump, coupler and selected resin before use.
Which pumps and injection materials are compatible?
Confirm the packer connection, coupler fit and operating limits with the selected pump and resin system before use. Use compatible PU injection resins or other injection materials approved for the system. A universal connection or maximum pressure rating is not specified.
