Pipe Restoration Technologies Awarded Patent for ePIPE In-Place Leak Sealing Technology

Pipe Restoration Technologies, LLC (PRT) announced that it has been awarded Patent #8343579 by the U.S. Patent and Trademark Office (USPTO) for enhancements to its ePIPE® technology.

The patented technology focuses on an internal barrier coating and leak sealing process that can be applied inside existing pipes while the piping system remains in place. This approach helps prevent leaks without relying on conventional pipe repair or full repiping methods.

What Patent #8343579 Covers

Patent #8343579 applies to ePIPE technology designed for internal pipe restoration and leak sealing. The process creates a protective barrier coating inside the pipe and supports in-place leak prevention for several types of piping systems, including:

• Potable water pipes
• Natural gas pipes
• Fire sprinkler systems
• Drain lines

By restoring pipes from the inside, the ePIPE process can help reduce disruption, avoid unnecessary demolition, and provide an alternative to traditional pipe replacement.

Continued Innovation in Pipe Restoration

“Our research and development team are proud of our ongoing innovation program and this accomplishment. This is our 3rd patent that focuses on in-place leak sealing technologies.” said Larry Gillanders, CEO

This patent further supports PRT’s ongoing commitment to developing innovative pipe restoration solutions that address corrosion, leaks, and aging infrastructure without the need for extensive repiping.

Recognition for ePIPE Innovation

The ACE DuraFlo®, ePIPE® team has been nominated twice for the U.S. National Medal of Technology and Innovation, the highest honor for technological achievement bestowed by the President of the United States on America’s leading innovators.

In Canada, Larry Gillanders was qualified as a candidate for the 2013 Manning Awards for Innovation, further recognizing the role of ePIPE technology in advancing pipe restoration and leak prevention.

Supporters of the ePIPE nomination for the U.S. National Medal of Technology and Innovation included Dr. Marc Edwards, Professor of Civil and Environmental Engineering at Virginia Tech. Dr. Edwards has also been honored by the White House with a National Science Foundation Presidential Faculty Fellowship.

A Patented Alternative to Conventional Pipe Replacement

For property owners, facility managers, utilities, and contractors, patented ePIPE technology provides an in-place option for restoring and protecting existing pipe systems. Instead of removing and replacing entire sections of pipe, the process is designed to apply a protective internal coating that helps seal leaks and extend the useful life of the piping system.

With Patent #8343579, Pipe Restoration Technologies continues to strengthen its intellectual property portfolio around in-place pipe restoration, internal barrier coating, and leak sealing technologies.
