Concrete Cancer / Spalling Repair Solutions
Concrete cancer and concrete spalling need more than a surface fix. Antoun provides specialist concrete repair solutions for compromised concrete structures. Since 1979, we support industrial, commercial and infrastructure projects across Australia with proven repair methods, high-performance products and the experience needed to protect structural integrity.
Repairs That Go Beyond the Surface
Concrete spalling is often a sign of active corrosion from deep within the slab. When moisture or air reach the internal steel reinforcement, it rusts. This chemical reaction expands the steel inside the concrete, creating internal pressure that causes cracking, spalling, rust staining and loss of concrete cover.
Antoun helps identify the full extent of the affected area before recommending repair options. This ensures the approach is appropriate for the structure, site conditions, reinforcing steel condition and long-term performance requirements.
When to Use Antoun’s Concrete Cancer Repair Solutions
Antoun’s concrete cancer and spalling repair solutions are suited to commercial, industrial and infrastructure
settings. Suitable applications include:
Spalling concrete on slabs, walls, columns and concrete structures
Affected concrete around steel bars, exposed steel or compromised concrete cover
Trip hazards caused by broken, lifted or deteriorating concrete
Concrete repair in marine environments or areas exposed to moisture
Structural repair where steel reinforcement requires cleaning, protection or replacement
Repair work where new concrete or polymer-modified material is required for reinstatement
Left untreated, concrete cancer continues the corrosion process and affects the durability and long-term performance of the
structure. Early diagnosis produces better repair outcomes and avoids unnecessary cost.

Additional Antoun Solutions
Concrete cancer and spalling repair often involve more than one scope of work. Antoun’s related services support the wider
repair process with solutions tailored to the structure, site conditions and program requirements.
Concrete Delivery
Concrete cancer and spalling repairs require the right preparation and strength delivered in the right quantity, particularly where access, timing or repair volume changes on site. Our concrete delivery service supports managed supply for reinstatement, patch repairs, slab repairs and larger replacement works.
Learn MoreBridge Decks
Bridge decks are highly exposed to moisture, vibration and traffic loads. We perform repair works that address damaged concrete, exposed reinforcement and reinstatement requirements in these demanding environments.
Concrete Slabs
Slabs with spalling can be dangerous and unusable. We provide concrete slab services for repairing, reinstating and replacing damaged concrete.
Specialist Equipment for Spalling Concrete Repairs
Concrete cancer repairs require controlled removal, accurate drilling, careful reinstatement and efficient material placement. Antoun's specialised equipment supports cleaner, faster and more precise work on demanding sites.
Why Choose Antoun
- Experience across complex concrete environments – Antoun has supported concrete repair and construction projects across Australia and internationally for over 45 years, with a track record spanning road authorities, airports, industrial sites, commercial projects and major infrastructure assets.
- Practical diagnosis before repair – Concrete cancer cannot be resolved by treating the surface alone. Our team considers the underlying causes, including corrosion, moisture ingress, poor waterproofing, inadequate cover and exposure, before recommending a repair approach.
- Product knowledge and installation capability – Our team combines high-performance repair materials, application expertise, specialised equipment and project coordination to deliver durable repair outcomes.
- Reduced downtime where access is limited – Where repair windows are restricted, Antoun plans the program, providing the materials along with the equipment to support efficient completion without compromising preparation quality or long-term performance.
Frequently Asked Questions
How long does a concrete cancer or spalling repair take?
Timing depends on the size of the affected area, access conditions, preparation requirements and the repair material selected. Our team can advise on expected duration once the site conditions and repair scope have been reviewed.
Can repair work be completed while the site remains operational?
In many cases, yes. Our team can help plan works around access limits, staging requirements and operational constraints to reduce disruption where possible.
Do you handle both small repairs and larger remediation projects?
Yes. Antoun can support localised concrete spalling repairs as well as broader remediation works across commercial, industrial and infrastructure environments.
How fast do Antoun's repair materials set?
Set and return-to-service times vary by product. CEMENT ALL™ dries in 15 minutes and can be painted over or driven on by a heavy vehicle within two hours. Rapid Set® Concrete Mix also sets in 15 minutes and is ready for traffic within one hour. Our team will confirm expected timing for MORTAR MIX™ and for your specific repair scope once site conditions have been reviewed.
What information should I provide when enquiring?
Useful details include the location of the damage, photos where available, approximate size of the affected area, site access conditions, exposure to moisture or salts and any structural reports already acquired.
