Restoring your property after a fire can be a daunting task. The damage caused by fire can significantly alter the structural integrity of your building, causing cracks, discolouration, and spalling, and requires immediate attention.

Here at ICE Cleaning, we offer our comprehensive fire cleaning solutions nationwide. Our technicians can restore the affected areas to their original condition while ensuring safety standards are met throughout the process. We can handle fire damage on various types of brick and stone, too, ensuring complete restoration.

Read on to learn more about fire-damaged concrete and the potential health hazards involved.

How fire affects concrete

A fire-damaged house can leave behind significant structural damage, especially to concrete structures. The heat from a fire uniquely interacts with the material, setting various reactions into motion within minutes.

Intense temperatures cause evaporation of water within the concrete, leading to cracking and spalling, where parts of the concrete break off due to thermal stress. This is why the fire damage repair process for concrete can be so complex.

If temperatures reach high enough levels for long periods, it could trigger chemical reactions within the cement paste, causing further degradation and compromising its strength.

Can concrete be restored?

Despite the difficulty of restoring fire-damaged concrete, with the right knowledge and tools it's possible to bring concrete surfaces back to their original state.

To repair fire damage on concrete surfaces effectively, professionals follow a meticulous process. This includes assessing structural damage caused by fire and water from firefighters' extinguishing efforts, targeting soot or smoke damage left behind, and drying out water damage.

Because of concrete's sustainability, it can easily be replaced with either a surface repair or a new slab entirely. Although this process can be extensive and costly, the results ensure a stable structure again.

Why you should not clean fire damage yourself

The results of a fire in your home can be overwhelming and it is natural to feel the need to start fixing things straight away. However, attempting to clean up after a fire yourself is not recommended for several reasons.

Cleaning fire-damaged concrete is not simple as it requires removing visible soot and debris, and scrubbing the air of any smoke particles left behind. Attempting this yourself could be dangerous due to toxic chemicals released during the fire. 

Fires often cause water damage from firefighters extinguishing the flames, too. This, combined with smoke damage, creates an unpleasant smell that permeates your property. The lingering odour is not just inconvenient, but the tiny smoke particles left behind pose health risks if inhaled.

Fire also damages the structural integrity of your property, making it incredibly unsafe to clean or interact with. Concrete that is cracked and coming away should be a cause for alarm as it may lead to the collapse of heavy debris that can cause injury.
