How to cure concrete cancer

Concrete cancer and concrete spalling are two conditions that often occur together and adversely affect a variety of structures. Concrete cancer is caused when the steel reinforcements within a concrete slab begin to rust, and as the metal rusts, it slowly expands. This inevitably causes the concrete around it to crack, become brittle and ultimately degrade. This degradation is known as concrete spalling. These conditions are especially common in older buildings due to the effects of time and weathering and are a key trigger for the leading remedial building service offered by Murphy’s Remedial Builders.

If you are undertaking a renovation, construction or heritage restoration project, you need to ensure you treat any signs of concrete cancer correctly to ensure the safety and longevity of your building, before extensive spalling occurs.

So, what are the signs of concrete cancer?

You can usually tell if concrete cancer has seeped in if:

– You notice cracked concrete
– Rust stains are leaking out from within the concrete layer
– There is bubbling or plating of the concrete render
– Leaks appear in the overhead concrete surface

What causes concrete cancer?

Concrete cancer can be caused by a large number of things, most commonly:

– Substrate that is poorly poured and has allowed moisture to seep in
– An inadequate preparation of the steel reinforcements when the concrete was originally poured
– Water seeping in with rain causing oxidisation
– Chemical reactions caused between incompatible metals used in the build process
– Stress fractures from weight bearing, or general wear and tear that allows water to penetrate the concrete

What are the dangers of concrete cancer?

If you notice concrete cancer, remedial building services are imperative because over time, with increased exposure, untreated concrete will begin to spall and fall away from your structure. Not only will this cause structural damage to the property, but it can also cause human danger.

What should you do?

If you notice concrete cancer, it is important to act quickly to prevent further damage from taking place. If you delay, you might find the costs of repair escalating, and danger increasing. Contact a heritage restoration or remedial building specialist to have the situation diagnosed and treated promptly.
