Corrosion Detection – Why Is Corrosion a Serious Problem?

Corrosion of metals is sometimes inactive, sometimes active. Some museum objects are susceptible to corrosion but remain stable because corrosion does not develop, while others are subject to active corrosion. Recognizing the early signs of active and destructive corrosion is an important aspect of preventive metal conservation. Few metal objects are immune to corrosion. Metals such as gold and platinum are the only ones that retain a bright, fully metallic appearance over a long period of time.

The Importance of GPR in Construction Projects

GPR (ground penetrating radar) is a non-destructive geophysical prospecting technique based on the analysis of propagation phenomena (refraction, reflection and diffraction) of high frequency electromagnetic waves (10 MHz to 2 GHz) in the subsoil. GPR, initially of an impulsive nature, is based on the excitation of the subsurface, from a transmitting antenna, through a short pulse train (1 to 50 ns) in order to detect, by means of a reception antenna, successive echoes associated with the contrasts of permittivities or conductivities encountered by electromagnetic waves during their propagation. These contrasts reflect the presence of buried targets or basement stratification. The use of frequency-based GPR is much more recent due to its associated instrumental constraints and is the subject of a significant amount of current research.

How Long Does It Take for a Ground Penetrating Radar (Gpr) To Scan Ground?

Ground Penetrating Radar (GPR) is a non-destructive geophysical technique based on the propagation and reflection of electromagnetic waves from 20 MHz to 3 GHz. It is sensitive to changes in the electromagnetic properties of the medium (permittivity, conductivity and magnetic susceptibility). Investigations are usually carried out by moving the antenna on the surface, with or without contact with the ground. Measurements are taken at regular intervals, which allows a quick image of the basement structure.

What Is the Role of Gpr in Underground Locations?

Ground Entrance (RPS) or Ground Entering Radar (GPR) first appeared around the turn of the twentieth century, where they were used as non-destructive devices in photographing soil and storm cellars. This framework’s first application occured in 1910, when it was used to locate buried targets – and it has evolved since then! Fast forward to the 1970s, ground radar saw a fast rise within the military space, particularly in the discovery of anti-personnel mines.

What Is the Best Method to Detect Corrosion?

Corrosion can be one of the greatest threats to the longevity of equipment. Without proper monitoring, large industrial assets such as power lines or pipelines can wear out slowly due to corrosion, causing leaks or failures and contributing to poor performance and reliability. In extreme cases, if corrosion is not monitored, it can result in complete equipment failure, posing risks to personnel safety, huge equipment costs and subsequent environmental damage.

Is GPR Effective?

GPR, or ground-penetrating radar, uses radio waves to capture images of embedded objects. It is a non-intrusive detection method that allows technicians to locate underground utilities and other objects such as live wires, post-tension cables, utilities, conduits, pipes, and voids. By identifying such objects before excavating, one can avoid potential damage and the associated safety risks and cost burdens. The all-important question is, is GPR effective? In short, yes, it is highly effective. Let’s explore how GPR can profoundly benefit your project.

The Importance of Corrosion Detection

Corrosion, although invisible to the naked eye in its early stages, is a latent threat that can undermine the durability and safety of infrastructure and materials. It not only threatens physical integrity, but also has a considerable economic cost for businesses and society.

While corrosion is a natural and unavoidable phenomenon, its detection and proactive management have become a priority, especially in regions like Quebec, where extreme climatic variations accentuate its impact.

In this article, we delve into the complex world of corrosion, its effects, and the crucial importance of professional detection in countering its devastating effects.

What Is Corrosion?

Corrosion is the destruction or deterioration of a material due to a reaction with its environment. The term can refer to a process or to the damage caused by such a process.

Although different types of material are affected by corrosion, iron is the most common victim. When iron is exposed to oxygen and water, the result is a red iron oxide commonly known as rust. Continue reading “The Importance of Corrosion Detection”
