Polyurea coatings are excellent for industrial structures such as underground pipelines and water tanks. But did you know these coatings are the perfect solution to use in a drum storage area for secondary containment?

What is secondary containment? 

If you work with hazardous chemicals, you probably know all about these systems. Secondary containment systems establish an extra line of protection if something happens to your primary containment system. For instance, if a storage drum that holds chemicals should burst, the secondary system will block any liquid from spilling out and damaging the environment. It's a temporary measure that shields the environment until the proper actions can be taken to fix the primary system.

Polyurea coatings are great for any secondary containment systems, such as:

  • Chemical facilities
  • Sumps and trenches
  • Drum storage spaces
  • Petroleum storage

The coating forms a leak-proof barrier that prevents any material inside the primary containment unit from escaping. Polyurea solutions are not only watertight but are very flexible. So if it's a frozen cold kind of day and everything feels tight, the chemical will shield you from any cracks. The same goes for a sweltering heatwave, where everything doubles in size. The polyurea will keep everything in place.

We've also stated that polyurea coatings are resistant to water damage, such as corrosion or rust. But that's not the only weather factor that can do some damage. Although the sun can be great for your mood and skin, all that ultraviolet exposure can affect a storage tank. For instance, if you have a polyethylene tank, constant exposure to the UV light can make the material fragile, leading to cracking. However, this doesn't happen to a polyurea solution.

Some businesses use a rubber lining, paint, or other surface protection to use as a secondary containment system. But that can lead to difficulties:

    • A rubber lining doesn't last nearly as long as a polyurea coating.
    • A rubber coating doesn't have the same abrasion and corrosion resistance.
    • There may be weaknesses in these types of coatings that a chemically aggressive fluid can exploit
    • They can be expensive as compared to a polyurea solution.
    • There's a chance that a rubber lining can absorb and possibly release materials that cause contamination.


Polyurea is the most dependable and durable way for an industry to provide true protection. If you need a secondary containment system for the materials you work with and are considering using a polyurea coating, go with the best.
