Concrete Cancer Repairs on the Gold Coast
One of the most common problems in all coastal regions like the Gold Coast is Concrete Cancer or Concrete Spalling. Concrete cancer is a sign of wear and tear and is caused when the steel reinforcing the slab begins to rust. As the steel starts to rust, it expands to eight times its volume, causing the surrounding concrete to become brittle and crack – this is known as spalling or breaking into smaller pieces. Spalling, in turn, worsens the issue by further exposing the steel and adjacent reinforcements to the elements, accelerating the level of corrosion and the process of disrepair. This highly impacts the building and compromises the integrity of the structure. It is therefore important to note that concrete cancer can be dangerous if left untreated.
Here are some common signs to look for that indicate concrete cancer:
- Concrete cracks
- Rust stains that seem to leak out from the concrete
- Bubbling of concrete render
- Roof leaks or any other leaks visible in internal walls
- Concrete expanding outwards
So what can we do about concrete cancer and how can prevent it from happening? The best way to prevent Concrete Cancer is waterproofing so make sure you invest in good quality waterproofing membranes to help keep water leakage to a minimum. Another preventative measure is to ensure that any standing water issues (internal leaks and drips) is fixed straight away. Same goes with cracks. As soon as you spot a crack, make sure to deal with it right away to avoid further exposing the steel to the elements. Painting the concrete is also another way to prevent concrete cancer as most paints are specifically designed to resist corrosion. Lastly, just like humans, buildings need regular check-ups too. Make sure to find someone who can check on the building regularly and help maintain the integrity of the structure.
And while indeed prevention is better than cure, sometimes concrete cancer cannot be helped from happening.
