Does Heat Affect Your Flooring?- Summer Problems

Dealing with heat in the summer can be annoying for many people. We’re not used to such high temperatures, especially since England is used to rain and cloud pretty much all year round. Heat doesn’t just affect us though; it can also affect your flooring.

In your industrial buildings, concrete may very well be the main, if only, component covering your floors in seamlessly smooth shades of grey…unless you’ve opted for  industrial floor painting, in which case your floors may be many different colours. It’s important that concrete, one of the strongest and most durable substances, can withstand temperatures above ambient in order to retain its mechanical, functional and load-bearing capacity.

This is made possible due to its mixing components which give the concrete:

  • Low thermal conductivity
  • Slow strength degradation
  • High heat capacity

With these fantastic properties you’d expect it to be virtually impossible for concrete to be damaged due to heat right? Well the majority of the time it is, but it’s not impossible.

Though severe heat from our sun can cause changes in the concrete’s properties, the second main cause of heat affecting your flooring is fire. Fire is considered one of the harshest elements, melting plastics, warping metals and turning wood into charcoal, so it’s no surprise that it can also affect the state of concrete.

When heated up, concrete changes its properties, though the extent of damage is dependent on the strength of the heat and the length of exposure. There are a number of visual ways you can see heat damage in your flooring…


Cracks can occur in concrete for a number of elemental and environmental reasons. Perhaps the earth it is sitting on has shifted, such as with subsidence, perhaps your concrete flooring is old and worn through usage, in desperate need of repairing, or perhaps it’s the heat. Cracks in your flooring can sometimes seem like minor damages and not worth dealing with. Don’t be fooled. Cracks can be the first sign that the properties in your concrete flooring have changed due to heat damage, and if you’ve experienced a fire or a long, hot week, it’s always best to pay close attention to your concrete flooring. Catching any damage early can prevent you from having to deal with a particularly costly repair.

Spalled Areas

Spalling is the breaking and fragmentation of your concrete flooring. This can become a health and safety hazard if ignored, not only due to your employees tripping over, but also to the structure of your warehouse or building. If you have suspended concrete flooring, the floor’s load-bearing capacity could be compromised or significantly weaker than before.





A lot of the time concrete covers metal frames. In heat- be it fire or a scorching summer- these metal frames could potentially warp under the pressure, causing deformities to occur on the surface of your flooring. As with spalling, this could become potentially dangerous for your employees, as working on uneven flooring can affect both productivity in the workplace and become hazardous to the men and women working there.

Repairing your concrete and industrial flooring, if you notice any of these visual damages, is important for both the safety of your employees and for your budget. Leaving damaged surfaces too long can cause them to worsen, meaning what could have been a potentially harmless repair could turn into a costly resurface job.

How Can You Check For Heat Damage?

One way you can check for heat damage in concrete is by tapping the surface. When concrete is heated up, it becomes more porous meaning that it emits a duller tap than an undamaged floor. However, it’s always best to have a professional come out and check that your concrete flooring hasn’t been damaged in these cases, or to assess the best methods for fixing the damage.
