Concrete cancer, also known as concrete deterioration, is a common problem caused by low concrete cover or carbonation of concrete. It can be a danger to people and property if large chunks of concrete break down and fall from a building. Fortunately, there are several treatments available to solve this issue. In this article, we'll discuss the different methods of treating and preventing concrete cancer, as well as the importance of getting expert help. The most common treatment for concrete cancer is to remove all chipped and cracked concrete to reveal the steel inside.
This steel is then cleaned and corrosion-free using various techniques. When carbonation of concrete and concrete does not cover steel properly, polymer-modified repair is often used. This method starts by removing the concrete around the affected area and cleaning up the rusted steel. Then, a steel primer is applied and a polymer-modified material is placed on top.
Typically, an anti-carbonation sealant is also placed over the entire surface of the concrete to reinforce its strength. Chemical water repellency can be added to the concrete surface itself by applying Resistain, a waterproofing sealant for concrete. This material is immersed in concrete to a depth of 10 mm, binds to the concrete structure at the molecular level and forms a water repellent barrier. Periodic maintenance checks are essential for identifying any problems in the early stages of repairs. This will help improve the service life and reduce the lifecycle cost of concrete structures. Waterproofing coatings should be applied and inspected regularly for imperfections. Another treatment for concrete cancer is to remove all concrete contaminated with chloride.
This process is usually more tedious than the previous one. Flat concrete roofs are an example of a building structure that is particularly vulnerable to leaks and water-driven concrete cancer if not properly waterproofed. Waterstop Solutions teams are available for all your concrete repair and remedial waterproofing needs in Brisbane, Gold Coast, Sunshine Coast and Sydney. The individual professional will be able to more accurately identify the cause of the problem and recommend an appropriate solution. Regardless of whether the damage is severe or moderate, waterproofing and integral sealing after repair are important to minimize the risk of cancer recurrence in concrete.
