Residential Structures

70% of concrete repairs fail within 10 years, and the #1 cause of failure is corrosion of the reinforcement. By proactively targeting the root cause of the problem (corrosion) instead of reacting to the symptoms (cracks, spalls), we can help condo owners get ahead of the issue, and greatly reduce future repairs. This not only leads to significant financial savings over the life of the building, but also makes the building safer, proividing peace of mind to residents that corrosion is being addressed. 

Concrete is like a hard sponge, it absorbs particles from its surrounding environment. Reinforcing steel is well-protected in the high pH of fresh concrete, but over time this environment can change, primarily due to the following 2 factors.

1: Chlorides (salts) available in the atmosphere in coastal locations, or from de-icing procedures in colder climates, penetrate into the conctrete and attack the passive oxide layer on the surface of the reinforcing steel. Once this passive layer is compromised, the chlorides catalyze the corrosion reactions, leading to accelerated corrosion damage. 

2: Carbonation is the reduction in pH of the concrete environment surrounding the reinforcing steel. Carbon dioxide available from the atmosphere reacts with water present in the concrete to form carbonic acid. Once the pH decreases, the passive oxide layer protecting the steel is compromised and the corrosion process begins. 

Absolutely! At NoCo, we understand that every property is unique and comes with its own set of challenges, budgets, and requirements when it comes to corrosion protection. We carry a variety of technologies aimed at protecting everything from a small concrete repair, to holistic protection of an entire structure.
