Perma-Liner Industries is celebrating 20 years of manufacturing in the trenchless pipeline rehabilitation industry. Founded in 1999 by Jerry D’Hulster, the company was the first relining company to achieve NSF approval, which allowed for CIPP to be used on the plumbing side for plumbing code approvals. The business was acquired in 2013 by Triwater Holdings, a Chicago-based water company, and is now a Triwater’s Waterline Renewal Technologies division, which also includes the brands LMK Technologies and AP/M Permaform.
