Established in 1999, Cornell is the only licensed installer of NuFlow pipe lining technology in Atlantic Canada.

Our push-in-place lining process allows us to repair piping systems using existing access points. Coupled with NuFlow’s product line, this noninvasive approach to pipe repair, pipe renewal, and trenchless sewer repair returns the lined pipe to a like new condition. Trenchless pipe repair is often the preferred solution for damaged drains when piping is located beneath slabs, driveways, or mature landscaping.

Inspection, cleaning, repair.

Through constant improvements and investment in technological advances, Cornell is an industry leader in trenchless pipe repair. High-resolution video inspection and locating allows us to see exactly what the situation is before repairs begin. Additionally, we offer micro-cutting and water-jetting services to remove tree roots and the most stubborn of clogs.

Trenchless sewer repair is as efficient as it sounds. Sewer issues can be remedied – usually within a day – with minimal disruption to building occupants. Cured-in-place liner solutions (CIPP), including both traditional time-cure epoxies and our UV-activated cold-cure system, reduces cure times to as little as fifteen minutes. The use of UV-activated resins offers a greener, more sustainable solution that also shortens curing time without sacrificing the repair’s performance or longevity. Liners can be installed in pipes ranging in diameters from 3 to 12 inches.
