Grooved mechanical piping has been changing the way contractors do business for more than 85 years, but this method of pipe joining is still unknown or misunderstood in some areas of the commercial building industry.

Pipe Restoration Technologies LLC (PRT) announced that it has been awarded Patent No. 8033242 by the U.S. Patent and Trademark Office (USPTO) for enhancements to the ePIPE® in-place pipe restoration and internal leak sealing system.

California State University, Los Angeles, made the decision to not let a leaking, underground HVAC pipe slow down campus activity. Use of a no-dig technology provided a cost-effective solution that did not require demolition or disruption to the campus grounds.

Operating under a joint venture with Albin Carlson & Co., Patrick Energy was awarded a design-build contract to replace the aging steam system and support infrastructure at the Soo Locks.
