Effective Concrete Cancer Repair In Progress – Gold Coast Car Park

Here is one of our accomplished senior technicians with extensive concrete repair and remedial waterproofing experience – Pumping out quality work in an underground carpark at the Gold Coast.


“Concrete cancer” is rust – specifically within reinforcing steel. Unfortunately, the problem is likely to be much more extensive than symptoms on the concrete surface suggest. Once established, the rusting will spread along the reinforcing in each direction. It is impossible to know the full extent of the damage until the concrete is chiselled away.

Steel reinforcing in concrete rusts because of either chloride ions or carbonation. When steel rusts it expands up to eight times its volume, which can then cause rigid concrete to spall (break into smaller pieces). This can accelerate the rusting of adjacent reinforcing by exposing it directly to the environment.

Several factors predetermine the risk of concrete cancer, including proximity to the coastline and a built-up environment; the degree of concrete cover to steel reinforcing; the presence of differential metals; the quality and density of coating systems; cracking, joint and penetration detailing; and the level of preventative maintenance.

The treatment of concrete cancer must consider appropriate weatherproofing and/or waterproofing as part of a complete solution. Otherwise, the repair work may remain a temporary fix as the underlying cause is likely to continue to affect the structure, depending on the situation.

It is recommended that a suitable protective coating is applied to the treatment area upon completion of the repair work, depending on the application requirements.

Occasionally, concrete repair scenarios call for us to consult with specialist remedial engineers within our network, depending on the complexity of the work and how it may interact with a building.

Our extensive experience on major civil projects has afforded Waterstop Solutions opportunities to design with industry-leading engineers and tackle some of the most complex concrete repair challenges imaginable in the built environment. Using this knowledge, we can provide you with a range of options to best meet your project criteria.
