Concrete Cancer: How to Identify and Treat It

Concrete cancer is a destructive building maintenance problem that, if left untreated, can not only cost you more economically as a homeowner, but can also pose a significant safety and liability risk. It occurs when steel reinforcement inside a concrete slab begins to rust and expand, displacing the surrounding concrete and causing it to become brittle and crack. At Danrae Group, we understand the causes and remedies of concrete chipping and cancer. Common signs of concrete cancer include cracking, crumbling, or flaking of concrete, rust spots or bubbles on concrete or cement plaster, and leaks in the ceiling and walls. If left untreated, it can be a danger to people and other property if large chunks of concrete break down and fall from a building.

The best way to deal with concrete cancer effectively is with full project management. This includes visiting the site to provide a full assessment of the condition and design of the solution. Remedies may include site-specific electrochemical treatment for near-ocean properties, or simply removing damaged concrete, cleaning or removing affected steel, and replacing with new material. An anti-carbonation coating or other specialized coating can be applied to strengthen and preserve the concrete. Repairing and filling small cracks will help stop the spread of concrete cancer, but the key to a successful remedy is timely and professional identification and treatment.

Aspro spacers can also eliminate the threat of concrete cancer. If you find evidence of concrete shedding or concrete cancer, you must act quickly to prevent continued damage.
