Concrete cancer, also known as concrete spalling, is a common problem that occurs when the steel reinforcement within concrete structures becomes corroded due to exposure to the elements. This corrosion causes the steel to expand, creating cracks and spalling in the surrounding concrete. These cracks and spalling not only weaken the structure, but they also provide a pathway for further corrosion, ultimately reducing the life of the structure. This is when you need to consider concrete cancer repairs.
Concrete cancer is particularly prevalent in coastal areas where water entry or lack of concrete cover in the initial construction can lead to corrosion. However, it can also occur in other environments due to exposure to chemicals and other aggressive elements.
At Binet Constructions, we understand the importance of addressing concrete cancer as soon as it is identified. Our team of experts works closely with consulting engineers to diagnose and repair the problem using the most appropriate method based on the cause and severity of the deterioration. We take into account technical and economic factors, such as ease of application, material costs, finish product appearance requirements and maintenance, to ensure that the concrete cancer repair work is of the highest quality and structural requirements.
Our concrete cancer repair process includes removing all damaged concrete and repairing or replacing all affected reinforcing. We then patch using highly specialised concrete repair products. We have a long-standing relationship with the manufacturers of these products, which enables us to provide the best possible product for the particular application.
An example of a recent project involving a multi-residential complex with an intricate concrete cancer issue can be found here. We have the experience and expertise necessary to address concrete cancer in all types of structures, and we work closely with our clients to ensure that their repair needs are met.
