How to Identify and Treat Concrete Cancer

Concrete cancer, also known as concrete corrosion, is a serious problem that can affect the structural integrity of a building if left undiagnosed and untreated. It is caused by the oxidation of embedded metals, such as reinforcing steel, due to exposure to air and water. The process of corrosion leads to expansion of the metal structure, which in turn causes chipping and further exposure of the reinforcing structure. This creates a vicious cycle that can cause extensive and costly property damage.

It is important to be proactive in evaluating and repairing concrete cancer before it worsens. Regular maintenance checks can help identify any problems in the early stages of repair, which will improve the service life and reduce the lifecycle cost of concrete structures. Signs of concrete deterioration include bubbling concrete plaster, roof leaks, internal wall leaks, or concrete that expands outward. If it is a case of chloride contamination in a building near the ocean, specialized repair work may be necessary to treat concrete cancer.

For situations where carbonation of concrete and low concrete coverage are the problem, an engineer might recommend the use of a polymer-modified repair system. Waterproofing is also an important remedy to stop concrete shedding and Projex Group supplies high-end PVC sheet membranes for this purpose. Once you find evidence of concrete shedding or concrete cancer, it is essential to act quickly to prevent further damage. Flat concrete roofs are particularly vulnerable to leaks and water-driven concrete cancer if they are not properly waterproofed.
