RESTORE STRENGTH. EXTEND LIFE.

Concrete cancer occurs when water, carbon dioxide and chlorides penetrate concrete and reach the steel reinforcement, causing it to rust, expand and crack the surrounding concrete.

Our proven repair systems remove the damaged concrete, treat the reinforcement and restore the structure using high-performance materials designed to protect and extend the life of your concrete.

We combine technical expertise with premium materials to deliver repairs that are built to last.

WHAT IS
CONCRETE CANCER?

Concrete cancer is the corrosion of steel reinforcement caused by moisture, salts and carbon dioxide penetrating the concrete. As the steel rusts, it expands, causing cracking, spalling and loss of structural integrity.

MORE THAN A
SURFACE DEFECT.

Visible cracking and spalling can be signs of damage beneath the surface. Corrosion may extend beyond the exposed area, so the condition of both the concrete and the embedded steel needs to be assessed.

COMMON SIGNS & CAUSES
OF CONCRETE CANCER

Concrete cancer is a progressive deterioration caused by environmental factors. Identifying the signs early and understanding the causes is critical to preventing structural damage and costly repairs.

Rust Stains

Orange-brown staining from steel corrosion bleeding through the concrete.

Cracking

Surface cracks allow moisture and harmful agents to penetrate deeper.

Drummy Concrete

Hollow sounds indicate voids or delamination beneath the surface.

Delamination

Layers of concrete separate, reducing bond and strength.

Spalling

Flaking or chipping exposes reinforcement to moisture and salts.

Water Ingress

Moisture drives corrosion and accelerates deterioration.

Chloride Attack

Chlorides from saltwater penetrate and break down steel protection.

Carbonation

CO₂ in the air lowers pH, weakening concrete and enabling corrosion.

EARLY INTERVENTION PREVENTS ESCALATION.

Timely inspection and remediation can extend the life of your structure and save on future repair costs.

WHAT CAUSES CONCRETE CANCER &
CONCRETE SPALLING?

Deterioration is often accelerated by a combination of environmental, material and construction factors that lead to corrosion of steel reinforcement.

Magnesite Flooring

High-magnesium trowelled floors can react with moisture, causing expansion and cracking.

Proximity to the Coast

Salt-laden coastal air accelerates corrosion, especially in exposed concrete structures.

Water Penetration

Moisture ingress weakens concrete and promotes steel reinforcement corrosion.

High Salt Exposure

Salt spray and chlorides penetrate concrete, attacking reinforcement over time.

Carbonation

CO₂ reduces concrete alkalinity, breaking down its natural protection for steel.

Age & Environmental Conditions

Time, UV, rain, heat and weather cycles gradually break down concrete integrity.

Insufficient Concrete Cover

Inadequate cover leaves steel vulnerable to moisture, salts and carbonation.

Substandard Construction Techniques

Poor design, mixing, placement and curing compromise concrete strength and durability.

Failed Waterproofing

Compromised membranes and sealants allow water ingress and internal damage.

Movement & Cracking

Structural movement and cracks create pathways for water, chlorides and CO₂.

WHY CAN’T WE JUST
PATCH REPAIR
CONCRETE CANCER?

Because concrete cancer isn’t just a surface issue. Patching only treats what’s visible. The corrosion continues underneath, leading to recurring damage, rust stains, and costly repairs.

CORROSION CONTINUES UNDERNEATH

Patches can’t stop rust from spreading to untouched steel.

PATCHES DON’T BOND LONG TERM

Moisture, salts and movement can cause patched areas to fail.

DAMAGE RETURNS

The underlying issue resurfaces, often worse than before.

MORE COSTLY OVER TIME

Temporary fixes lead to repeated repairs and higher costs.

PATCH THE CAUSE — NOT JUST THE DAMAGE.

Proper remediation identifies the extent of corrosion, removes unsound concrete, treats the reinforcement and rebuilds the affected area correctly.

WATER INGRESS

Water can enter through cracks, failed membranes, joints, drainage defects and porous concrete. When moisture repeatedly reaches embedded reinforcement, corrosion can continue even after the obvious surface defect appears.

Where water ingress is contributing to the damage, the source should be considered as part of the wider remediation strategy.

No, concrete cancer and concrete spalling are related, but they do not mean exactly the same thing.

Concrete cancer commonly refers to deterioration associated with reinforcement corrosion. Concrete spalling describes concrete that is cracking, flaking, chipping or breaking away from the surface.

Reinforcement corrosion is a common cause of concrete spalling, but not every spalled area is necessarily caused by concrete cancer.

Concrete cancer develops when moisture, oxygen or contaminants reach embedded steel reinforcement and cause corrosion.

Contributing factors may include failed waterproofing, leaking joints, cracking, carbonation, chloride or salt exposure, inadequate concrete cover, poor drainage, damaged coatings and construction defects.

The cause should be assessed in relation to the affected structure, surrounding finishes and possible sources of moisture before the repair method is selected.

Concrete cancer may become urgent when loose concrete could fall or when deterioration affects an important structural element.

Warning signs requiring prompt professional assessment include falling concrete, exposed reinforcement, bulging or displaced sections, significant cracking, rapidly worsening damage or deterioration affecting beams, columns and suspended slabs.

Access beneath loose concrete should be restricted where there is a risk to people, vehicles or surrounding property. Engineering advice may also be required where structural capacity or stability could be affected.

The repair method depends on the condition of the concrete, reinforcement, affected structure and agreed project scope.

A typical repair may involve removing loose and unsound concrete, exposing and cleaning affected reinforcement, treating corrosion, preparing the remaining concrete and reinstating the area with a compatible concrete repair material.

Additional reinforcement, waterproofing, protective coatings or engineering requirements may also form part of the repair where necessary.

Small, accessible repairs may take several days.

Projects involving multiple repair areas, difficult access, structural elements, curing requirements, waterproofing or occupied buildings may require staged work over several weeks.

A more accurate timeframe can be provided after the affected areas have been inspected and the repair scope has been prepared.

Our minimum job charge is $2,900 including GST where a minimum charge applies.

The final cost depends on the number and depth of the repair areas, reinforcement condition, access requirements, structural complexity, waterproofing and any surrounding finishes that require reinstatement.

An on-site inspection is normally required before an accurate, project-specific quotation can be prepared.

Concrete deterioration can return if active corrosion, unsound concrete or the source of moisture and contaminant ingress is not adequately addressed.

A properly planned repair aims to remove affected material, prepare the reinforcement and concrete correctly, install a compatible repair system and address contributing defects where included in the project scope.

The long-term performance of the repair also depends on exposure conditions, maintenance, waterproofing and the condition of surrounding concrete.

Strata approval may be required where the affected concrete forms part of common property or the work affects structural or shared building elements.

Responsibility depends on the registered strata plan, property boundaries, applicable by-laws, previous alterations and the location of the deterioration.

Owners should notify their strata manager or owners corporation before arranging repairs to balconies, suspended slabs, beams, columns, façades or other potentially common-property concrete.

Insurance coverage depends on the cause of the damage and the wording of the relevant policy.

Gradual corrosion, ageing, maintenance problems, construction defects or long-term water ingress may be treated differently from damage caused by a sudden insured event.

Property owners, strata committees and building managers should confirm their individual coverage directly with their insurer or insurance adviser.
