Spalling & Flaking Concrete Treatment

Concrete cancer occurs when water reaches the steel reinforcement inside the slab, causing it to rust, expand, and break the surrounding concrete.We remove the damaged areas, treat the steel, and rebuild the structure to prevent the issue from returning.

Structural Crack Repair

Cracks in ceilings, walls, balconies or columns are often a sign of deeper structural movement.
We assess the cause, stabilise the section, and apply professional epoxy or mortar repair systems.

Steel Reinforcement Treatment

Exposed or rusted steel bars (rebar) are a major warning sign.We clean, treat, prime, and encapsulate the steel using industry-standard protective systems.

Epoxy Injection & Bonding

For structural cracks, we inject high-strength epoxy or polyurethane materials to restore strength and prevent moisture from re-entering.

Waterproofing Around Concrete Repairs

Many concrete failures begin with poor waterproofing.We provide membranes, coating systems, and sealing work to protect your building long-term.

What Is Concrete Cancer?
Signs You Need Concrete Repair
Progress report & Record

Concrete cancer (also called concrete spalling) happens when cracks allow water to reach the internal steel reinforcement.Once the steel rusts, it expands — breaking the concrete from the inside.

Common causes include:

  • Balcony or rooftop water leaks
  • Poor waterproofing
  • Cracks left untreated
  • Age of the building
  • Coastal exposure
  • Incorrect original construction

If you see any of the following, book an inspection:

  • Cracks in concrete walls or ceilings
  • Flaking, bubbling, or crumbling concrete
  • Rust stains leaking down walls
  • Bulging or lifting concrete patches
  • Concrete falling off balconies or ceilings
  • Damp marks, leaks or water ingress
  • Exposed or rusted steel reinforcement

‍Report: If you’re unsure, send us a photo — we’ll advise you for free.

Report update to homeowners

  • Filled repaired areas using high-strength structural grout
  • Rebuilt missing concrete sections
  • Ensured correct bonding between new grout and old concrete
  • Restored the original slab profile

Key point: Structural grout reinstates the strength of the slab and prevents future delamination.
‍Report: Progress photos showing patch reinstatement and bonding.
