At Flooring And Grinding We Offer FREE Concrete Cancer Inspections Throughout Australia

At Flooring and Grinding, we provide no-obligation concrete cancer inspections across Australia to help property owners address this serious structural issue early. Our qualified technicians carry out comprehensive assessments to pinpoint the root cause of concrete deterioration affecting your structure.

Pinpointing the origin of the problem is critical to halting the progression of concrete cancer. Once we’ve identified the underlying issue—whether it’s due to water ingress, poor concrete coverage, or corroded reinforcement—we recommend the most effective repair solution tailored to your building’s needs.

If you suspect signs of concrete cancer in your home or commercial property, get in touch with us today to arrange a FREE site inspection. Our expert team will assess the damage, explain your options, and provide a detailed quote outlining the most suitable and lasting treatment plan.

10 Warning Signs That May Indicate Concrete Cancer

1. Visible Rust Stains
Reddish-brown streaks or rust marks on concrete surfaces are often early signs that steel reinforcement within the structure has started to corrode — a common trigger for concrete cancer.

2. Eroded or Worn Concrete Surfaces
When concrete lacks a proper protective seal, its porous surface absorbs moisture more readily. This accelerates deterioration and increases the risk of concrete cancer forming beneath the surface.

3. Cracks and Fractures
Cracks, whether hairline or large, allow water to seep through and reach the internal steel reinforcement. This water exposure causes rusting, which expands and leads to further cracking and structural damage.

4. Water Stains Or Pooling Water
Persistent damp patches, moisture marks, or water pooling on horizontal surfaces often point to drainage issues. These conditions increase the chance of water penetrating the concrete and causing rusting of the internal steel.

5. Damaged Or Ineffective Joints
Expansion or control joints are designed to accommodate concrete movement. If these joints are broken, missing, or poorly installed, stress fractures can occur, giving water a direct path to the steel below.

6. Insufficient Concrete Coverage Over Steel
If the reinforcement is placed too close to the concrete surface, it becomes vulnerable to environmental moisture. This minimal protective layer allows quicker water penetration and promotes early-stage corrosion.

7. Rusting Fixtures (e.g., Balustrade Anchors)
Steel fixings or connectors such as balustrade posts can rust and transfer that corrosion into the surrounding concrete. This process often initiates deeper internal damage and early concrete cancer symptoms.

8. Bubbling Or Peeling Paint
Paint that lifts, blisters, or bubbles — particularly on ceilings or balcony undersides — often indicates moisture is trapped behind the surface. This moisture may be tied to underlying concrete cancer.

9. Hollow-Sounding Concrete
When tapped, certain sections of concrete may produce a hollow sound. This typically suggests delamination or separation between surface layers and internal steel, a condition often associated with advanced concrete cancer.

10. Steel Reinforcement Becoming Visible
In severe cases, portions of the concrete may chip or fall away, leaving reinforcing bars visibly exposed. This is one of the most obvious and urgent signs that concrete cancer is actively deteriorating the structure.

Step 1: Free On-Site Assessment
We begin by visiting your property to conduct a thorough site evaluation. After the inspection, we provide a no-obligation quote tailored to the scope and complexity of your concrete cancer issues.

Step 2: Problem Diagnosis
Our experts investigate the source of the concrete spalling or delamination. We pinpoint the damaged areas, assess the severity, and determine the most effective repair method.

Step 3: Precise Cutting & Edge Preparation
The deteriorated concrete around the affected zone is carefully cut back. We trim the edges to create a clean, structurally sound area for repair, removing any compromised material.

Step 4: Controlled Jackhammering
Using dust-minimising jackhammering tools, our team removes all loose and damaged concrete near the exposed reinforcing steel, ensuring we don’t cause further damage to the surrounding surface.

Step 5: Rust Removal from Reinforcement
We use an angle grinder fitted with a wire brush to remove all surface rust and corrosion from the steel reinforcement, preparing it for proper treatment.

Step 6: Surface Cleaning
All exposed concrete and reinforcement are thoroughly cleaned to remove dust, debris, and contaminants. This ensures proper adhesion of protective coatings and repair materials.

Step 7: Application of Anti-Corrosion Primers
An industrial-grade rust inhibitor and epoxy primer are applied to the cleaned reinforcement bars to halt corrosion and extend the structural lifespan.

Step 8: Steel Reinforcement Replacement (If Needed)
Where necessary, we install new reinforcing steel bars to restore the structural integrity of the affected concrete area.

Step 9: Protective Coating
A waterproof and anti-corrosive coating is applied over the reinforcement to shield it from future moisture infiltration and corrosion.

Step 10: Concrete Reinstatement
We restore the area with a high-strength repair mortar or concrete mix, applied at the correct thickness and left to cure properly for a seamless and long-lasting finish.
