One of Calgary’s tallest office towers had the flat, roof parapets replaced. After the parapets were replaced, water was discovered leaking into premium tenant spaces. Revive Pipes installed Cured in Place Pipe (CIPP) structural liners in all of the roof drains in the replaced roofs, stopping all of the water leaks into the tenant space. Revive Pipes saved the building $40,000 and prevented the newly replaced roof membrane from being damaged during the conventional repair.
The roof parapets of the skyscraper were replaced to ensure the roofs would remain water tight for many years. Unfortunately, during rainfalls after the roof replacement, it was discovered that water was leaking at several locations into the premium tenant space on the top floor of the facility. It was difficult for the property maintenance team to determine where the leaks were originating from, so an engineering firm was hired to study the problem and recommend solutions.
The engineering firm concluded that the leaks were originating from the Mechanical Joint (MJ) between the drain body and the first length of the rainwater drain pipe. A couple of temporary repairs were suggested as well as a full replacement of the leaking MJ joint.
Typical invasive repairs would have involved:
Removal of the paving stones, insulation, gravel and membrane around each roof drain
Chip out the existing drain body and first length of pipe
Install a new drain body and MJ seal
Cast concrete back in around the drain body
Reroof the surrounding area and tie it into the drain body
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.
We saved the client $20,000 on the repair and provided them with additional piece of mind by lining all of the roof drains in case other Mechanical Joints (MJ) started to leak in the future.
Revive Pipes has used our specialized tools, materials and techniques to install Cured in Place Pipe (CIPP) structural liners to repair swimming pools, hot tubs and decorative fountains. Swimming pool, hot tub and decorative fountain piping systems are particularly complex, often with many more ninety (90) degree bends with a tight or sharp turning radius. Because of the complexity of swimming pool, hot tub and fountain piping, not all systems or locations within the piping system can be repaired using Revive Pipes Cured in Place Pipe (CIPP) structural lining process.
When a pool system is experiencing systemic leaks at PVC pipe joints, Revive Pipes Pressure Pipe Internal Epoxy Barrier Coating service may be the more suitable repair option. Our epoxy barrier coating service fully coats the internal surface of the piping system with an epoxy barrier coating to seal all of the joint leaks.

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.
