Polyurea Tank Linings | Coatings

There are different blends of Polyurea available for tank linings, depending on the containment requirements. Polyurea tank linings are flexible as well as abrasion resistant. They are equally suitable for applications in the waste water industry as they are for potable water and food containment.

See the datasheets at the bottom of this page.

Water | Wastewater:

The wastewater industry is a major user of Polyurea tank linings. This is due to the fact that they can withstand most chemical and chemical gasses produced at waste treatment plants. In addition anti-microbial additives can be used in the polyurea to decrease the microbial growth on the lining. Importantly Polyurea coatings form a seamless membrane. Therefore they conform to poles, pumps and other internal structures. Even large diameter pipes, manholes and lift stations are perfect candidates for Polyurea. Polyurea is even available in hard structural formulations that reinforce pipes and manholes. Since sprayed on linings conform precisely they make the perfect structural coating.

Potable Water:

Polyurea is the perfect tank lining for water and salt water. It is even available in USDA-acceptable and NSF-approved to ANSI-NSF 61 standard for potable water storage. It does not leach materials into or from water. Furthermore it is seamless so provides a perfect lining for drinking water.

Practical Uses

The practical uses are endless. The video playing in this section shows a mobile tanker truck that we lined. We've done many of these trucks. A common problem we see is the tank cracks where it attaches to the frame. Due to this, the polyurea tank lining can be applied with a floating section above the problem area so if moves or cracks in the future it won't damage the lining.

Since the polyurea is flexible and has over 300% elongation it is the perfect solution for severe duty applications.


Tanks are one of the most common things you find in an industrial environment. The shapes and sizes are endless. You'll find them above and below ground. Moreover they are made of steel, concrete and an endless array of other compositions. Some are open and some sealed. In addition some are stationary while others are portable but one thing is for sure, put something in them and the deterioration starts. Even something as harmless as water will cause steel to rust away. It will cause concrete to crumble as it goes through freeze - thaw cycles. Obviously put more aggressive liquids in and the process happens faster.

Clearly the solution is to isolate the tank from it's contents.


A Polyurea tank lining is spray on, it's flexible in addition to having 100%-300% elongation and is resistant to a wide array of chemicals. Hence it can be installed into tanks where other tank lining systems just won't work.
