What Is Concrete Cancer?

Concrete cancer is a common term used to describe serious concrete deterioration caused by rusting steel reinforcement inside concrete structures.

Concrete itself contains embedded steel reinforcement bars that help strengthen the structure. Over time, moisture, oxygen, and contaminants can penetrate the concrete and reach the internal steel.

As the steel begins to rust, it expands. This expansion creates pressure inside the concrete, eventually causing the concrete to crack, lift, break apart, and deteriorate.

The term “concrete cancer” is commonly used because the deterioration can continue spreading through the concrete structure if left untreated.

Concrete cancer may appear as:

– Cracked concrete
– Rust stains
– Bubbling concrete surfaces
– Loose concrete
– Flaking or chipping concrete
– Exposed reinforcement steel
– Concrete breaking away from walls, slabs, or ceilings

In many cases, the damage begins internally before becoming visible on the surface.

Concrete cancer is commonly found in:

– Balconies
– Apartment buildings
– Car parks
– Rooftops
– Suspended slabs
– Concrete walls
– Basements
– Staircases
– Structural concrete areas

Buildings exposed to moisture, salt air, weather conditions, and ageing concrete are often more vulnerable to concrete cancer deterioration.

Concrete cancer can range from minor localised deterioration through to severe structural concrete damage depending on how advanced the deterioration becomes.
