Certifications & Approvals


Epoxies for drain, sanitary, and storm lines are manufactured at Nu Flow’s 16,000 square foot facility in Oshawa, Ontario, Canada. The liner meets or exceeds the physical properties set forth in ASTM standard F-1743 for CIPP rehabilitation and ASTM standard F-1216 for Inversion rehabilitation. A structural liner that reinforces host pipe, Nu Flow’s liner meets or exceeds ASTM D790, D638, and D543 standards and has a life expectancy of over 50 years.

Testing documents and references by third party are available. Nu Flow believes in quality assurance and has an excellent track record at delivering products and services that meet or exceed industry standards.
