Transforming Watermain Rehabilitation with Nukote Coating Solutions

Water is essential for life, and maintaining a reliable and safe water supply is crucial for communities everywhere. That’s where watermain rehabilitation comes into play. It’s all about fixing and upgrading the pipes that carry water to our homes, schools, and businesses. In this blog post we’ll explore how Nukote Coating Systems from IMC are revolutionizing this field.

The Challenge of Aging Water Infrastructure

Many cities and towns have water pipes that are old and wearing out. This can lead to leaks, bursts, and even water contamination. Fixing these problems is a big task. Traditional methods often involve digging up streets and replacing pipes, which is time-consuming, disruptive, and expensive. That’s where trenchless technology and innovative solutions like Nukote Coating Solutions come in.

Understanding Watermain Rehabilitation with Elastomeric Coatings

The Process of Applying Elastomeric Coatings

  1. Preparation: Initially, the water flow is redirected, and the specific pipe section needing rehabilitation is isolated. This step involves cleaning the pipe to remove any corrosion or tuberculation (build-up inside the pipe).
  2. Application: Next, a special elastomeric coating is applied to the interior surface of the pipe. This can be done through spraying manually or robotically depending on pipe size. The type of coating—whether it’s simply for anticorrosion or semi or fully structural—depends on the pipe’s specific requirements.
  3. Curing: The elastomeric coatings offered by IMC have incredibly fast gel times allowing for a rapid return to service. This lining process forms a strong, continuous barrier inside the pipe.
  4. Reintroduction: Finally, the rehabilitated pipe is brought back into service, with the water flow restored to its normal path.

The Benefits of Using Elastomeric Coatings for Watermain Repair

  • Cost-Effective: This method is often more affordable than traditional pipe replacement, especially for large-scale projects.
  • Trenchless Technology: It minimizes disruption to the surrounding area and reduces the need for extensive excavation.
  • Improved Performance: The coating often improves the pipe’s hydraulic capacity due to reduced friction, prevents leaks, and protects against internal corrosion and external contamination.
  • Extended the Lifespan: Properly maintained, these coatings can extend the life of watermains by 50 years or more.
  • Environmentally Friendly: The trenchless approach and reduced material usage have a lower environmental impact than traditional methods. These lining systems are safe for the environment containing no solvents, VOCs, or styrene.


  • Pipe Condition: Depending on the condition of the pipe different spray applied lining systems will be recommended.  Severely damaged pipes may require a Class IV fully structural lining system while a relatively healthy pipe may only require an anti-corrosion protective coating.
  • Pipe Size: 3” in diameter and up. 
  • Cost Factors: The overall cost can vary based on pipe size, coating type, and project complexity.

Nukote Elastomeric Coating Products: A Closer Look

Nukote Coating Solutions, offered by IMC/Nukote Canada, are at the forefront of watermain rehabilitation. These innovative coatings act as a protective skin for pipes, applied directly to the interior of existing pipelines. This unique approach creates a durable barrier that effectively prevents leaks and combats corrosion and damage.

Unlike traditional pipe replacement methods, the application of Nukote coatings is much faster and significantly less disruptive, making it a preferred choice for modern infrastructure maintenance.
