Concrete Repairs

Protecting Structures from Deterioration

Concrete deterioration, commonly known as concrete cancer or spalling, is one of the most serious issues facing multi-storey residential buildings. Left untreated, it can compromise structural safety, allow water ingress, and escalate repair costs. At Act Now, we provide tailored concrete repair solutions that go beyond surface patching to address the root cause of damage. Our methodology combines detailed condition assessments, steel reinforcement treatment, and reinstatement using high-strength repair mortars. Where required, we apply protective coatings and waterproof membranes to prevent recurrence.

How We Repair & Protect Concrete

We provide targeted concrete repair services that address both visible damage and underlying causes such as reinforcement corrosion and water ingress. Our approach ensures structural safety, compliance, and long-term durability for multi-storey residential, commercial, and strata properties.

Our expertise includes:

  • Investigation & diagnosis of concrete cancer (spalling)
  • Breakout, cleaning & treatment of corroded reinforcement
  • High-strength reinstatement with structural repair mortars
  • Crack injection & expansion joint sealing
  • Protective coatings & waterproofing for exposed concrete
  • Rope-access repair methods for high or difficult façades

Every project is carried out to Australian Standards, ensuring quality outcomes, safety, and peace of mind for our clients.

The Importance of Timely Concrete Repairs

Water damage is one of the most expensive and disruptive issues for strata properties and new developments. Effective waterproofing is not just a requirement — it’s an investment in the long-term performance of your building.

  • Arrests concrete cancer before it spreads through the structure
  • Restores the strength and stability of affected elements
  • Protects steel reinforcement against future corrosion
  • Maintains the building’s asset value and compliance with safety standards
  • Enables access to hard-to-reach façades without costly scaffolding

At ACT NOW, we help strata managers and developers safeguard their buildings with tailored, future-proof waterproofing solutions.

Frequently asked questions

What exactly is concrete cancer?

Concrete cancer, or spalling, occurs when steel reinforcement inside concrete begins to corrode. As the steel rusts, it expands, causing cracking, delamination, and chunks of concrete to break away.

Why is concrete cancer a serious issue for strata buildings?

Beyond being a safety hazard for residents, untreated spalling weakens structural elements and can spread rapidly. It also increases repair costs the longer it is left unaddressed.

How can we detect concrete cancer early?

Warning signs include cracks, rust stains, bubbling concrete, and exposed reinforcement. Regular building inspections are the best way to identify issues before they escalate.
