How to Protect Infrastructure from Corrosion

corrosion

Corrosion is an environmental hazard that effects buried materials such as metals and concrete that comes in direct contact with soil or bedrocks. This is a complex occurrence, with a great number of variables involved. Corrosion can result in various damage to the infrastructure. Proper measures are required to make sure the integrity and stability of the infrastructure aren’t compromised due to corrosion.

Let’s look at ways you can protect your infrastructure from corrosion.

Protective Coatings

A popular method used to fight corrosion is the use of coatings with anti-corrosive properties that ensure that the infrastructure has an extended life. Coatings and linings are used as the number one defense system against deterioration. They are often applied in combination with cathodic protection systems to provide a well-rounded protection to the structure. The Cathodic protection technology is great as it uses electoral currents to counteract the external corrosion of a structure that contains various materials. CP will strike the core problem and prevent from existing corrosion to worsen.

Use of Steel Cages

Gabions are cages engineered from double twisted woven steel making it strong and durable. Once delivered on the site they are placed with stones around the infrastructure. There are various uses of these cages, but they are generally used by construction companies to control structures from corrosion as well as erosion. Most cages (for example https://www.maccaferri.com/us/products/gabions/) are made using steel of superior quality, which provides long-term protection to any infrastructure.

Underground Climate

Various studies have been conducted to observe the impact of corrosion on infrastructure. Attempting to control the underground soil environment by trying to control the corrosive processes may be successful to some extent. When it comes to infrastructure, the rate of soil corrosion can be controlled to some extent by focusing on the types of metals used to build the infrastructure. Cathodic protection is one of the commonly used methods for controlling the underground climate.

Anodization

Aluminum mixtures are often used to make materials more resistant to wear and tear, and corrosion. It’s commonly used on metallic structures and components in cases that are susceptible to come in contact with other elements that can expedite the corrosion process.

Galvanization

Galvanized metals are a great option as the thin layer coating of zinc provides protection against corrosion. The process is simple as the zinc oxidizes when it is exposed to the air creating a protective coating on the materials used in your infrastructure. A builder should anyways try and coat the materials used in order to prolong the wear and tear. This will keep the building stronger for longer.

Carbon Fiber

This is another great method of preventing the corrosion of infrastructure. This involves filing pipes with sheets of carbon fiber or any metal surface used in your infrastructure. This method does not only prevent corrosion but also strengthens the materials, prevents cracks from forming and stop any sort of leaks.

Sacrificial Anode Protection

Anode protection involves the use of material that is more active than the ones you want to protect. This is a great way of protecting your infrastructure from corrosion. The anode will corrode eventually so it will need to be replaced once that happens. The process is slow, giving you sufficient amount of time to consistently focus and maintain your infrastructure.

It’s important to focus on the design, material used, construction, operation and maintenance of infrastructure facilities will save you a lot of money in repair, maintenance and replacements costs. If you are able to control the corrosion process in the infrastructure then you can prevent permanent damage from taking place which will save you money and other resources in the long run. Builders should implement strategies that will prevent corrosion from taking place so that even if does start to happen they have an action plan to tackle the situation without it getting worse.

In order to prevent infrastructure corrosion, you should continuously look into preventive measures. Remember, both corrosion and erosion are nature’s forces at work. You cannot completely eliminate their possibilities, but investing in the right protective and preventive measures mean you can prevent it to a great extent.
