Concrete Cancer

Article Summary: 

This blog discusses the concept of concrete cancer, which is the deterioration of steel reinforced concrete structures due to rust and corrosion of the steel reinforcement. Moisture entering through tiny cracks in concrete creates an electrochemical reaction, which causes the metal bars within the concrete to rust and expand, leading to cracks and spalling of the concrete. Proper maintenance and early detection of damage are essential to prevent expensive repairs and disruption to residents. Prevention methods include preventing water from penetrating concrete and cleaning garage floors to prevent salt build-up. A Building Science specialist can advise on identifying and addressing concerns.
