Besides the fact that the damaged concrete looks messy, it is usually a sign of a much serious problem that can compromise the entire foundation of your property. 


Concrete spalling occurs for various reasons, but one of the most common is the natural process of carbonation. The cracks that might appear on your driveway or house are usually caused by water that seeped into concrete and began the corrosion process, but it is not rare that concrete deteriorates due to poor installation or mechanical stress. 


Therefore, it is important to do everything we can to avoid concrete spalling, and a few of the efficient ways include special injections, protective membranes and spalling remediations. If you are looking for a team of professional remedial building professionals to effectively protect your concrete from early deterioration and make your premises as safe as possible, give us a call now. In the meantime, let us tell you more about the causes and the adequate preventive measures of the concrete spalling. 


The Most Common Causes of Concrete Spalling


Besides the corrosion, concrete’s exposure to fire can also lead to its spalling due to the evaporation that creates internal pressure and weakens the bonding materials. The same rule applies for the water that freezes inside the concrete as the built-up pressure in its pores surpasses the concrete’s flexibility power causing it to crack. 


We mentioned that the poor installation is also responsible for the concrete spalling, and this relates to concrete mix preparation, joint construction and of course, its pouring process. If the ration in the mix is not suitable, concrete spalling is inevitable. On the other hand, insufficient depth of concrete over rebars will keep them exposed to moisture and lead to corrosion. 


There is also the inevitable weather factor that makes the concrete expand in the warm weather and contract in the cold. After some time, it is quite normal to expect concrete spalling and breaking. Another natural process is concrete aging as its efficiency and stability start to drop over time. And finally, let’s not forget to mention the usual problem of the residents of the Australian coastline – chloride ions concrete corrosion. As the coastal air is loaded with it and the concrete is porous, its surface will be eventually damaged by this essential substance of the sea salt. 


Is There a Way to Prevent Further Concrete Spalling?


First of all, spalling prevention begins even before the concrete is poured. For example, using the air-entrained concrete, letting it cure well and applying a water-repellent sealer on the slab is considered to be an adequate procedure for concrete slab prevention. 


But what to do if there are clear indications of the concrete damage on an already established property? This is where our concrete spalling remedial professionals can help you.
