Common Mistakes In PU Injection Grouting

    PU injection grouting is a popular method for repairing cracks in concrete structures.

  • Improper surface preparation: Failing to clean and dry the concrete surface thoroughly can prevent the grout from bonding properly.
  • Incorrect injection pressure: Using too much pressure can cause the grout to leak out of the crack and result in an uneven repair.
  • Inadequate injection time: Not allowing enough time for the grout to fully penetrate and fill the crack can leave gaps and voids.
  • Using the wrong type of grout: Using a grout that is too rigid or too flexible can lead to cracking or separation from the concrete.

  • Identify the problem area: First, the damaged or cracked area in the concrete is identified.
  • Drill holes: Small holes are drilled into the concrete, typically spaced a few inches apart, to allow for the injection of the grout.
  • Inject the grout: A specially formulated polyurethane grout is injected into the holes using a high-pressure pump. The grout fills any voids or gaps in the concrete, effectively repairing the structure.
  • Monitor the repair: Once the grout has been injected, the repair area should be monitored for any further movement or cracking
  • Finish the repair: After the grout has cured, any excess material can be removed and the surface can be finished to match the surrounding concrete.
