Certifications and Approvals

Epoxies for drain, sanitary, and storm lines are manufactured at Nu Flow’s Ontario plant in Ajax.  Our cured in a place pipe liners CIPP meet or exceed the physical properties set forth in the 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 liners meet or exceed ASTM D790, D638, and D543 standards and have life expectancies of over 50 years.

Testing documents and references by third parties are available. At Nu Flow we believe in quality assurance and have an excellent track record of delivering products that meet or exceed industry standards.
