A seven (7) story residential complex experienced several incidents of nasty flooding and raw sewage contamination due the corrosion cracking of four (4) sanitary drain stacks over only a couple of years.
When Revive Pipes was contacted, we performed video inspections and provided an assessment on the remaining sanitary drain stacks in the building. Much of the cast iron drain pipe was experiencing pinhole leaks that were calcifying and sealing off on their own. These type of pinhole leaks are a warning sign that the piping system is at the end of its useful life.
Continuing to use the sanitary sewer stacks in the corroded, pitted and deteriorated condition that they were in would have resulted in more nasty flooding, damage to the facility and upset tenants. The property manager and building owner made a prudent decision to proactively install Cured in Place Pipe (CIPP) structural liners in the three (3) remaining original wastewater stacks in the most critical condition.
The property management company for the building had worked with Revive Pipes in the past and was aware of our capabilities so they contacted us to look at the roof drain problem. Revive Pipes installed Cured in Place Pipe (CIPP) structural liners in all twenty-one (21) of the roof drains in the newly replaced roof to seal the Mechanical Joints (MJ). The building owner wanted to install liners in all of the roof drains rather than only the four (4) roof drains that were found to be leaking to give them certainty moving forward that they would not have leaks from any of the roof drains in the future. Our non-invasive roof drain repair didn’t disturb the newly replaced roof membrane, which would have created more uncertainty about potential leaks in the future.
Revive Pipes installed Cured in Place Pipe (CIPP) structural liners in three (3) remaining sanitary sewer stacks saving the building and its tenants from impending floods of raw sewage and the subsequent disruptive cleanup and sewer stack repair. The building owner saved 30% on the cost of a traditional wastewater stack replacement, no tenants were displaced from their units and contractor time on site was reduced by 80%.
Prior to finding out about Revive Pipes innovative sewer replacement service, the property endured the typical sewer stack replacement on the first four (4) vertical stacks.
Each vertical stack took 1 ½ to 2 months to replace by the time all floors were completed.
Tenants in the immediate vicinity of the work area had to be vacated while the work was being completed on their floor
Work areas on each floor had to be sealed off to decrease the amount of dust entering tenant spaces
Walls on each floor were torn out from floor to ceiling to access the pipe.
Cinder block chases where the sewer stacks ran were busted open from floor to ceiling
The corroded old cast iron pipe was cut out and the raw sewage contaminated pipe had to be wrapped and sealed before carrying it out of the building to be disposed of in a specialized landfill for biohazards
The new cast iron pipe was installed
Toilets and sinks were reconnected to the wastewater stack
Cinderblocks were reinstalled in the chase
Drywall was reinstalled and taped, mudded and sanded
Walls were repainted
Cleaners vacuumed and wiped up all residual construction dust that wasn’t contained within the work enclosure
Revive Pipes removed the corrosion buildup in the remaining sanitary stacks and installed Cured In Place Pipe (CIPP) structural liners in 3 of the most problematic remaining stacks in only 6 days. Our specialized tools, equipment and techniques allowed us to provide a non-invasive sanitary sewer stack repair to our client.
Revive Pipes is able to install Cured in Place Pipe (CIPP) structural liners in multi-story buildings regardless of how many stories high the building is. We typically require access points to the vertical stacks every five (5) to seven (7) stories depending on the configuration of the system.

NuFlow Installer | Revive Pipes has been Nu Flow's exclusive Nu Drain, Cured in Place Pipe (CIPP) installer in Alberta for the better part of the past decade. The high profile sewer rehabilitation projects that we have completed inside of buildings in Edmonton and Calgary have forged Revive Pipes reputation as an elite installer in Nu Flow's worldwide network of licensees of the Nu Drain system.
Nu Flow has been a world leader in developing and manufacturing patented Cured in Place Pipe (CIPP) systems that are uniquely suited for rehabilitating wastewater systems inside of buildings. Sewer systems inside of buildings are significantly more complex than systems outside of buildings for many reasons including:
Smaller pipe diameter
Multiple bends in the pipe
Multiple branches of varying sizes connecting to the pipe being lined.
The area above and adjacent to the pipe is occupied by people living or working
Nu Flow developed a patented Cured in Place Pipe (CIPP) liner assembly that uses a pull-in-place (PIP) installation method unlike most Cured in Place Pipe (CIPP) assemblies that use an inversion installation method. The pull-in-place system used in conjunction with Nu Flow's patented Nu Drain system allows us to install liners in many situations without excavating floors or demolishing walls to create access points.
The Nu Flow, Nu Drain system has the flexibility to also be installed from a single access point in some situations when a second access point is not available. Nu Flow Cured in Place Pipe (CIPP) liners can be pushed into place in situations where Cured in Place Pipe (CIPP) inversion contractors would likely have to create an excavation point for their access. Access points that we can install Nu Flow Cured in Place Pipe (CIPP) liners from include cleanouts, roof vents, toilet closet flanges and manholes.
The Nu Flow system can also form around ninety (90) degree elbows and bends without stretching and thinning of the lining material in the outer radius of the liner. This characteristic ensures the structural integrity of Nu Flow's Nu Drain liner is maintained throughout the bend, unlike an inversion liner.
The pull-in-place (PIP) installation method allows Nu Flow liners to be accurately placed, often with an inch of accuracy in a sewer pipe system. Cured in Place Pipe (CIPP) inversion systems suffer from inaccuracies and uncertainty in where liners will terminate in the sewer pipe. Because of the stretching fabric used with inversion lining and the difficulty in measuring liner distances around bends, inversion liners will often terminate at an unintended spot in the sewer system. This can leave part of the sewer pipe unlined or the inversion liner could go too far and block a branch connection or travel into a main pipe, blocking the main sewer line. Revive Pipes uses Nu Flow's patented Nu Drain system in these situations to remove the uncertainty of where the liner will terminate and ensure the sewer pipe is lined properly.
Nu Flow Cured in Place Pipe (CIPP) liners can be used in point repairs that are hundreds of feet from an access point on either side of the section of sewer in need of repair. In situations where all of the pipe except for a small section is in good condition, an installation of a Nu Flow spot repair avoids disruptive excavation or demolition.
As the exclusive Nu Flow, Nu Drain licensee in Alberta for nearly the last decade, Revive Pipes has the experience and technical ability to install Nu Flow Cured in Place Pipe (CIPP) in complex sewer configurations inside of buildings.
