Perma-Lateral Lining D.C. Perma-Liner Industries held a large demonstration in Washington D.C. on the Perma-Lateral lining system. They featured the Perma-Lateral system with a hot water unit for faster cure times. The Perma-Lateral system will reline virtually any pipe material and it renews the pipe life to a minimum of 50 years per ASTM F1216 third party testing. If you live in the Washington D.C. area and are interested in learning more about the Perma-Lateral lining system, please call us with any questions or to set up a live demonstration to see the ease of this system yourself!
