United Trade: For the ultimate treatment of your concrete cancer


As time goes on, you may start to notice that your building or other structure is beginning to show signs of wear and tear. This is known as concrete cancer, the term used to refer to the rusting of steel reinforcements that are contained within a concrete slab.

As this steel starts to rust, it expands and this causes displacement of the surrounding concrete. This in turn becomes brittle and will begin to crack, which will accelerate the process of disrepair. Look out for signs like concrete spalling (cracks and so on), rust stains that look like they’re seeping out from inside the concrete, bubbling of concrete render, or leaks that crop up in overhead concrete.

There could be various reasons for your concrete cancer. Typically, our engineers follow the following process

  • Determine what is causing concrete cancer.
  • Evaluate how severe concrete cancer and/or spalling is.
  • Develop a process to repair and/or rebuild the concrete structure.
  • An engineer may seek quotes or tender submissions from capable remedial contractors.
  • The spalling concrete around the reinforcing bar is removed.
  • A rust inhibitor is applied to the reinforcing steel.
  • An epoxy, mortar epoxy, and/or cementitious material is used to patch the area.
  • Cracks are repaired using a technique called ‘crack injection’ where suitable epoxy resins or special mortars are injected.
  • Treatment of concrete cancer may include waterproofing.
  • The area should be re-painted/re-coated.

When it comes to concrete cancer, there’s no one-size-fits-all solution. The best repair option depends on your building materials and the extent of the damage. Regardless of whether the damage is severe or moderate, waterproofing and comprehensive sealing after the repair are important to minimize the risk of concrete cancer in the building.
