The determination of the cause of deterioration and the corrosion mechanism of concrete or steel structures are very important issues. The choice of cost-effective corrosion protection technology and an appropriate repair strategy are essential to ensure the integrity and proper functioning of the facilities.
In the last few years, technologies have been developed and consolidated which are an important innovation in the field of preventive and conservative maintenance of infrastructures. These technologies, already adopted favorably in many European and non-European countries, basically are intended to go in-depth and more detailed analysis of the infrastructures, providing a series of information that are now essential to guarantee the durability of the same.
We refer in particular to the assessment of the corrosion status of the reinforcement rods, with determination of its critical areas, as well as to systems aimed at identifying lesions or fractures on pre or post-compression cables, or at corrosion rate and the residual life expectancy of a structure, by means of non-destructive interventions on site which, combined with elaborate laboratory analysis, provide results and final evaluations.
The final reports derive from the know-how of specialized companies that use certified engineers in the field of corrosion supported by the technical contribution of prestigious accredited universities in this area on these specific issues.
All these tools and competence are made available to the technicians responsible for Maintenance and Safety, to provide them with the necessary support to safeguard the conservation of infrastructure.
In this regard, please note that it is the duty of every Technical Maintenance and Safety Manager to propose to their Administration the implementation of the aforementioned current regulations, in the most advanced technical formulations.
A correct diagnosis, carried out by expert technicians, remains a primary and irreplaceable approach to address the problems linked to the durability of reinforced concrete structures. This makes possible to identify the real problems of the structure using the correct repair method and above all, to get considerable savings in economic terms, focusing the maintenance interventions in the areas carefully identified and reported thanks to the preventive survey.
We are able to offer a complete package of non-destructive tests according to current standards for the assessment of the degradation conditions of any reinforced concrete structure, including:
Corrosion rate of steel in concrete
Mapping of the electrical potential of reinforcing bars
Mapping of the electrical resistance of the concrete
Carbonation depth test
Chloride ion content
Steel continuity measurement
Magnetic interference measurement
Cover meter measurement
Width and depth of cracks analysis
Steel coating thickness measurement
Fractographic and Metallographic Analysis
Residual life of the structure evaluation
All data for the various parameters are analyzed and processed by an internally developed software based on intelligent learning systems. Finally, a summary of data assessment and a corrosion classification report for each facility will be issued.
