Why is polyurea the perfect product for secondary containment projects?

Have you ever considered polyurea coatings for a secondary containment system? Perhaps you already have a wonderful product but lack the skills and resources to complete your containment project. Polyurea coatings might be the answer you have been looking for. Polyurea provides corrosion and abrasion protection for pipelines that carry abrasive and corrosive materials. 

These coatings are well-known in industrial constructions, such as underground pipes and water tanks. Nonetheless, how suitable they are for secondary containment systems is sometimes neglected. 

What Does Secondary Containment Mean?

 If the primary containment system fails, secondary containment systems give an extra line of defense. In the case of a spill or discharge, it acts as a control measure erected or built around a storage vessel to keep its contents from spilling into the drainage system. You may be familiar with these systems if you work with harmful chemicals. 

In general, it is a temporary barrier intended to keep any fluid in storage from escaping the confinement area so that it does not corrode or damage the surrounding environment, creating a risk to public health.

Polyurea as a secondary containment liner.

Polyurea solutions are not only flexible but also water-resistant. It acts as a barrier, keeping material from seeping out of the primary containment systems. Consequently, the polyurea will protect anything from cracking on a record-breaking cold day. While on a blistering hot day when everything doubles in size. Polyurea will keep everything together.

Water degradation, such as corrosion or rust, is not a problem for polyurea coatings. However, that is not the only weather aspect that might cause problems. A storage tank can be harmed by ultraviolet radiation. For example, frequent UV radiation exposure can cause the material to become brittle and shatter if you have a polyethylene tank. A polyurea solution, on the other hand, does not experience this.

The use of geotextile fabrics as intermediate substrates for secondary containment in the oil and gas industry has exploded due to the ease and speed of installation and their reusability. However, modern polyurea materials and process innovations accelerate this process while maintaining or improving quality and performance. Special equipment and applicators apply polyurea spray to properly prepared metal, concrete, and geotextile surfaces. 

The polyurea liners are pre-sprayed off-site using robotically operated equipment. Spraying the liners with robotics ensures equal thickness across the lining. This method of pre-spraying the liners is quickly gaining favor among facility owners and installing contractors since it significantly minimizes or eliminates job-site and environmental obstacles like wind and weather, which may hinder or even halt production and installation.

Problems due to other surface protectors.

Some companies use paints, rubber linings, and other surface protectors as secondary containment solutions. However, this might result in problems such as:

  • A rubber liner does not last nearly as long as a polyurea coating.
  • Rubber coatings may have flaws that a chemically active fluid might exploit.
  • A rubber coating does not have the same wear and corrosion resistance as a metal covering.
  • They can be more costly than a polyurea solution.
  • There is a potential that a rubber liner will absorb and release contaminants.

We now understand how important it is to safeguard the environment from harmful products. And the best way for the industry is to utilize the finest protection available. That perfect protection is a polyurea solution.
