Company presentation

Challenges of corrosion


BlueSpine is a young company specialized in the corrosion of reinforced concrete structures. Our expertise is based on 60 years of combined academic research and experience in this field. This gives us a critical perspective and a deep understanding of the complex physical phenomena involved in the early degradation of civil engineering structures.


When we founded BlueSpine, one observation became clear to us: corrosion is the main cause of premature aging of our infrastructures. No structure is spared, and many of them reach the end of their intended lifespan. Indeed, infrastructure built between the 1960s and 1980s, mostly constructed with reinforced concrete, was designed with a lifespan of 30 to 50 years. In this context, our infrastructure stock is reaching maturity and requires measures for the preservation of our built heritage.


The aging of our infrastructure poses several challenges. There is first and foremost an obvious economic issue: direct costs related to infrastructure corrosion are estimated at 2% of the GDP of industrialized countries. These costs include expenses directly related to corrosion damage such as structural repair works, or demolition and reconstruction of the structure. However, they do not take into account indirect costs such as loss of operation during repair works, maintenance costs, etc. There is also a significant social issue, as infrastructure degradation compromises the safety of users (risks of concrete collapse, structure collapse, etc.). Finally, the environmental impact of corrosion is not negligible. Indeed, cement production is one of the most polluting industries in the world, not to mention the energy required for steel production. Thus, rebuilding a new structure rather than rehabilitating an existing one represents a considerable ecological cost.

 

Face à ces constats et ces enjeux, il était pour nous essentiel de nous engager dans la lutte contre la corrosion, avec pour objectif de maximiser la durée de vie de notre patrimoine bâti.


Faced with these findings and challenges, it was essential for us to engage in the fight against corrosion, with the objective of maximizing the lifespan of our built heritage.

BlueSpine's activities

BlueSpine's engineering


Our engineering office conducts all studies related to corrosion activities and supports you on all complex issues related to this field.


Our diagnostic studies

Corrosion diagnosis is a crucial initial step in managing corrosion protection for structures. At Bluespine, we conduct corrosion diagnostics and assist you in analyzing complex results.


This study is devided in several essential phases. First, a visual inspection of the structure and an evaluation of the surface condition are carried out to map damages and possible former repairs. This step allows targeting areas for measurement during the survey.


We use non-destructive methods for chemical and electrochemical analyses of your structures. Potential mapping allows identifying corrosion clusters in an inspected area. The potential is measured according to a representative mesh, allowing drawing a map of steel potentials in the area. We then compare electrochemical potential gradients to highlight areas where this value drops abnormally, a sign of active corrosion zones.


We also perform resistivity mapping to complement the diagnosis and analyze the corrosion kinetics, guiding the choice of appropriate treatment.


Additional laboratory tests on samples are then carried out to determine the origin of the pathology, notably by measuring the carbonation front and chloride content. These analyses allow recommending the most suitable treatment for the structure. It is also recommended to perform other measurements (sulfates, for example) to assess the state of the concrete and adjust the treatment strategy based on these results.


BlueSpine develops corrosion diagnostic protocols and analyzes complex results, providing treatment recommendations tailored to the specificities of each structure. We are thus able to determine the origin, activity, and extent of the pathology on your structures.


Our durability studies

Once the characteristics of the structure and its environment are well understood, it becomes possible to estimate its approximate lifespan in the absence of treatment. We conduct durability studies to assess the residual lifespan of your structure, whether old or new, and we will provide recommendations on actions to optimize the maintenance of your infrastructure.


We perform advanced calculations and digital design to evaluate the progression of the pathogen in the concrete. We thus determine the time before the corrosion initiation phase begins and calculate the progression of corrosion over time based on the specificities of your structure.


Our approach takes into consideration external factors that influence the lifespan of your structure, such as the level of exposure to aggressive agents, the structural arrangements of the facility, and the concrete formulation. Thus, we are able to maximize the lifespan of a structure from its conception, by optimizing its geometry and selecting the most suitable materials for its use and environment.


Furthermore, these studies allow us to recommend preventive maintenance on structures even before considering treatment, offering long-term economic benefits for facility managers. They also help detect any corrosion activity upstream to avoid any future deterioration.


Cathodic protection design

Cathodic protection is a complex electrochemical treatment aimed at slowing down or stopping the corrosion of structures. BlueSpine performs the sizing of your cathodic protection system for all types of infrastructure.


This process involves targeting active corrosion areas to neutralize the corrosion current and protect the steel. To do this, an electric current is sent to counteract the corrosion current. The calculation of the necessary protection current depends on the diagnosis made on the structure as well as its technical and physical specifications, which requires precise design adapted to each structure.


BlueSpine guides you in the design of cathodic protection, regardless of the technological choice made (impressed current cathodic protection or galvanic). We assist you in selecting the equipment to optimize the system's performance while minimizing inherent risks. We determine the type, geometry, and quantity of anodes to install, as well as their position to ensure optimal protection of your structure. With our expertise in digital twins, we evaluate the treatment's effectiveness and adjust it based on the parameters identified during the diagnosis.


Our support to project owners and contractors

It is common, when a structure shows advanced signs of corrosion, to decide to demolish it for replacement. In the era of ecological transition, we are now able to offer solutions to rehabilitate these structures affected by corrosion. BlueSpine provides support to contractors and project owners in these rehabilitation projects involving steel corrosion issues in concrete.


We assist our counterparts in planning and managing rehabilitation projects, providing support, advice, and facilitating communication among all project stakeholders.

We can also validate cathodic protection design, assist the project manager in choosing suppliers, and manage all necessary data for the rehabilitation project. Our expertise covers the entire rehabilitation chain, thus offering comprehensive support to our clients.


Legal expertise

BlueSpine can act as a technical expert in legal expertise involving corrosion issues on reinforced or prestressed concrete structures. The main causes of damage related to corrosion are generally attributable to cathodic protection failures, design errors, and environmental factors.


We collaborate with legal experts to help determine the involvement of corrosion and its origin in the deterioration of the structure when a disaster occurs. Thanks to our certifications and confirmed experience in the field of corrosion, we are able to accurately identify the causes of the disaster as well as the responsibility of the various parties in the deterioration of the structure.
