In the bustling urban landscapes of Sydney, Melbourne, and beyond, a silent menace is eroding the structural integrity of buildings. Known as magnesite concrete cancer, this issue often goes unnoticed until it’s too late. As experts in building inspection and remediation, we at Elyment Group are shining a light on this critical problem, helping property owners and strata managers understand and address the risks.

Magnesite concrete cancer is a serious issue that can compromise a building’s structure.
What Exactly is Magnesite Concrete Cancer?
Magnesite flooring, a common choice in the mid-20th century for its soundproofing and levelling properties, is the culprit. When exposed to moisture—a common occurrence in bathrooms, kitchens, and laundries—the magnesite flooring absorbs the water and swells. This expansion puts immense pressure on the underlying concrete slab, leading to cracks and the eventual rusting of steel reinforcement bars. This process is what we call concrete cancer.
The Early Warning Signs You Can’t Afford to Miss
Recognising the symptoms early is crucial. Keep an eye out for these tell-tale signs:
- Visible cracks and bulges: Look for hairline cracks or larger fissures in concrete slabs and render.
- Chalky residue or white powder: This is a key indicator of magnesite breaking down.
- Rust stains: Brown or orange streaks seeping through the concrete signal that the steel reinforcement is rusting.
- Lifting tiles or flooring: As the magnesite swells, it can cause floor coverings to lift, bubble, or crack.
- Hollow sounds: Tapping on the floor and hearing a hollow sound can indicate delamination of the concrete.
How Does Magnesite Removal Protect Your Property?
Proper magnesite removal is not just about aesthetics; it’s a vital step in preserving your building’s structural health. Our process involves carefully removing the damaged magnesite and concrete, treating the corroded steel reinforcement, and then re-instating the area with a durable, modern material. This remediation not only fixes the existing problem but also prevents it from returning.
