Concrete Cancer Sydney
Concrete Cancer Sydney
What Is Concrete Cancer?
Concrete Cancer (also known as Concrete Spalling) is the aggressive rusting of steel reinforcement beams in the concrete slab.
As the steel rusts it expands, displacing the concrete around it, causing it to become brittle and crack thus accelerating the process. Which can be incredibly dangerous to the strength of the structure and flooring.
The alkali-silica reaction, more commonly known as “concrete cancer”, is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous silica found in many common aggregates, given sufficient moisture
Signs of Concrete Cancer include:
– Crazing and cracking concrete (Concrete Spalling)
– Rust stains which seem to leak out from within the concrete
– Bubbling (also called Plating) of concrete render
– Leaks that appear in overhead concrete surfaces
What Causes Concrete Cancer?
Concrete Cancer (also known as Concrete Spalling) is aggressive rusting of steel reinforcement beams in the concrete slab which can be incredibly dangerous to the strength of the structure and flooring.
Sydney’s older apartment developments have a topping of magnesite on concrete flooring that displays a smooth finish. Long-term exposure to moisture that occurs in household kitchens, bathrooms, laundries or balconies as well as windows, can lead to the magnesite releasing harmful chlorides.
Concrete Cancer is a serious problem that occurs within the concrete and it is caused by the steel reinforcing inside the concrete rusting. As the steel reinforcing rusts, it expands, causing the concrete around the steel to be displaced.
As the concrete becomes more displaced, more water gets into the steel, causing more Concrete Cancer (rusting) and the problem gets worse. The expansion of the steel causes the concrete to delaminate and results in Concrete Cancer. Concrete Cancer is where the concrete initially cracks and then starts to break away. While Concrete Cancer looks terrible, it can also be dangerous as pieces of concrete fall off and possibly hit people underneath. Concrete Cancer also weakens the strength of the concrete.

Can You Repair Concrete Cancer?
Concrete Cancer can start in a number of ways including using poorly treated reinforcing steel when the concrete is poured, having the ends of the reinforcing too close to the surface so that water can get to it, using incompatible metals (this causes a reaction), having fractures in the concrete as well as things such as Magnesite Flooring.
Dealing with Concrete Cancer is not a DIY job. Concrete Cancer will need to be removed via penetrating the concrete enough to reach the rusting steel reinforcement; thoroughly remove the rust; treat the steel, and waterproof the steel to ensure the problem does not occur again. Depending on the severity of the problem, the concrete repairers may use a technique called “crack” injection to create a water diverting membrane or, if the problem is serious, more invasive action may be required.
Just as a disease needs proper diagnosis and appropriate treatment, so does Concrete Cancer. However, there are several telltale signs of its presence that can alert you to the problem. Look for:
– Flaking concrete
– Cracking concrete
– Magnesite Flooring
– Rust stains that appear with no external cause
– Bubbles in concrete render (surface finishes)
– Leaks in a concrete roof or in internal walls
If you suspect Concrete Cancer is developing, call our Concrete Cancer specialist team immediately and let them diagnose and treat the problem. If you catch the problem early, the repair is usually much easier and cheaper than if you put it off and let the problem get worse.
If you suspect that you have Concrete Cancer in any form, it is important that you get treatment as soon as possible otherwise the problems will only get worse. Treatment needs to be done by qualified professionals as poor treatment will only hide and delay the problem.
It is not enough to just render over the concrete to hide the rusting steel, this is commonly done through layers of ardit by “home handymen” or “DIY” people to hide the issues and sell the property. The rusting process will just continue underneath, causing further displacement of the concrete and even necessitating the replacement of the reinforcing steel altogether. Rather, the cause of the Concrete Cancer needs to be appropriately identified before a fix can be applied once the cause is identified repairs can start
Concrete Cancer puts owners of the property at risk of negligence suits. Damage can occur through concrete pieces falling and injuring people, property, or even accidental death. Further, Concrete Cancer that is not attended to in a timely manner will only lead to further costs as the problem spreads.

Concrete Cancer Caused By Magnesite Flooring
When magnesite is exposed to moisture over prolonged periods of time, chloride ions from the magnesite 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 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 the 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 removal job. Concrete cancer had been caused by water leaking from various sources, saturating the magnesite 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.
