10 Possible Signs Of Concrete Cancer
1) Rust: Rust marks will appear and is a sign of Concrete Cancer.
2) Worn Surfaces: Unprotected, porous surfaces lead to water absorption and Concrete Cancer.
3) Cracked / Fractured Concrete: Cracks provide water access to the steel reinforcement instigating Concrete Cancer and fracturing the concrete enabling further water penetration.
4) Moisture Stains and Ponding: Inadequate drainage causes water to settle into concrete leading to Concrete Cancer. When water comes into contact with steel reinforcement, the steel rusts.
5) Failing Control and Expansion Joints: Joints that do not facilitate concrete movement can lead to concrete fracturing and Concrete Cancer.
6) inadequate Concrete Cover: Steel reinforcement too close to the surface makes it easier for water absorption resulting in Concrete Cancer.
7) Rusted Balustrade Fixings: Rust spreads to the embedded concrete starting the Concrete Cancer process.
8) Bubbling Paint: Paint that appears to be bubbling i.e. on soffits, often means Concrete Cancer is present.
9) Hollow Surfaces: Concrete surfaces that seem hollow usually have Concrete Cancer.
10) Exposed Steel Reinforcement: Concrete Cancer causes concrete to break away exposing the steel reinforcement.
Concrete Cancer Caused By Magnesite Flooring
When Magnesite Flooring is exposed to moisture over prolonged periods of time, chloride ions from the Magnesite Flooring diffuse into the pores of the underlying concrete slab eventually reaching the reinforcing steel.
As chloride levels in the slab reach the chloride threshold, corrosion of the steel reinforcement will begin to take place, the longer the exposure time to the moisture source, the more aggressive the corrosion of the steel reinforcement. Corrosion of this nature results in the pitting of the steel reinforcement where it loses its cross-sectional area and strength.
Iron oxide deposits also occur, causing expansive forces within the concrete. These forces cause cracking and Spalling Of Concrete around the corroding steel, a common name for this type of Concrete Spalling is Concrete Cancer.
Signs of Concrete Spalling were noted throughout various units in manly when Carpet Removal Sydney was on a commercial job site doing a strata Magnesite Flooring job. Concrete Cancer had been caused by water leaking from various sources, saturating the Magnesite Flooring for prolonged periods of time.
Magnesite Flooring can be removed with specialized equipment by our Magnesite Flooring removal specialist team. leaving the concrete slab in a condition that is ready to have new flooring installed on.
Although sometimes some Magnesite Flooring jobs will have Magnesite residue stuck to the floor even after the Magnesite Flooring has been jackhammered off. When this happens the remaining residue will need to be ground off using specialized equipment to restore your concrete slab back to a level, smooth state allowing a new flooring system to be installed or to allow the fresh concrete slab to be used as your new floor.
Concrete Cancer is often caused by Magnesite Flooring, Our team are Australia’s leading experts in the removal of Magnesite Flooring. Magnesite Flooring should always be removed for your safety as it can contain asbestos and often causes Concrete Cancer.

What Is Concrete Cancer?
Concrete Cancer is the term given to the process where rusting structural steel begins to rust and in doing so expands, creating stresses and fractures in the surrounding concrete. Because concrete is porous, it can absorb water and salt air very easily, which corrodes the steel inside.
This process is ongoing if not addressed according to structural engineer specifications. If left to develop, the fracturing concrete allows further areas of moisture penetration in turn leading to the development of larger and more numerous areas of Concrete Cancer.
This process is ongoing if the rusting steel is not correctly addressed and the surfaces are left with no waterproof coating. In time, initial small areas of Concrete Cancer become larger and more expensive to repair. In our experience this equates to growth in the damage of approximately 5% per year, directly impacting repair costs.
Concrete Cancer, cracked or damaged concrete is much more than just an eyesore. Left untreated, compromised concrete can quickly lead to serious structural problems requiring extensive remediation.
Concrete Cancer occurs when carbonation and high chloride levels in the environment (usually present in coastal locations) cause corrosion of concrete buildings. If it’s left untreated Concrete Cancer can lead to serious structural deterioration resulting in extensive and expensive repairs.
The expert Concrete Spalling Repair and waterproofing solutions from our team are an efficient and cost-efficient way of addressing Concrete Cancer and concrete cracks.
Concrete Cancer is a term used to describe the degradation of concrete structures often caused by interstitial contaminants in the concrete constituents, moisture ingress, and the alkali-silica reaction.
Chloride-contaminated constituents can find their way into concrete structures if sourced from a chloride-rich environment such as a coastal region. Chloride ingress can also be attributed to the structure’s surrounding environment, which is a particularly important issue in Australia.
The presence of free chloride ions in a reinforced concrete structure causes de-passivation of the steel reinforcement bars, allowing them to corrode. As the steel corrodes inside the structure, the reinforcement bars expand, inducing stress on the surrounding concrete and leading to Concrete Cancer.
Once initial cracks form in the Concrete Cancer processes, further degradation is accelerated as there is greater exposure to moisture ingress.
In the alkali-silica reaction, certain concrete constituents in the aggregate react with the alkali to form alkali-silica. This highly hygroscopic compound imbibes moisture from surrounding pores in the concrete structure.
This has the effect of creating a localised expansion in the alkali-silica-rich sites resulting in high internal localised stresses. When the concrete has become damaged by the alkali-silica reaction it can produce a characteristic cracking pattern on the surface with white alkali-silica gel emanating from this network of cracks.
The word Spall in engineering describes the chips or fragments of a material that is broken off a bigger object. The process of Spalling Of Concrete also known as spallation is the surface failure that occurs when a material such as concrete, brick, or limestone is subjected to excess moisture, corrosion, weathering, and much more. Concrete Spalling commonly known as (Concrete Cancer) is an eyesore and has the potential to be an extreme hazard.
What Is The Cause Of Concrete Cancer?
What Is The Cause Of Concrete Cancer? The large, glaringly obvious reason for Concrete Cancer is moisture in the concrete. Here are some more causes to be aware of for your concrete building or structure:
– Poor waterproofing that allows moisture into the concrete
– Salt air and chlorides if your building or structure is near the ocean or near a river
– Building defects can rapidly excel the growth of Concrete Cancer
– Humid or rainy weather and general wear and tear
– Poor quality concrete
– The earth foundation it is built on shifts and moves, promoting cracks
– Flooring systems such as Magnesite Flooring can cause Concrete Cancer.
