Project Summary

Cracked cast iron rainwater pipes in one of Calgary's many plus 15 walkways were heavily leaking whenever it rained.  The rainwater pipes were very difficult to access due to HVAC ducts and electrical cable trays in the way.  Revive Pipes installed Cured In Place Pipes (CIPP) inside of the deteriorated cast iron drain pipes without disturbing the public or nearby businesses.

Situation

A plus 15 walkway in downtown Calgary was flooding every time it rained.  The cast iron rainwater pipes in the ceiling had cracked in several places, so when the pipes filled with water, it would flow heavily out of the cracks in the pipe.  The water was damaging the ceilings and causing a slippery hazard on the floors.  Unfortunately, the ceiling space was full of electrical racks and HVAC ducting, making the rainwater plumbing impossible to access without removing a lot of other building systems components first.

Typical Invasive Repairs

The traditional repair would have required much, if not all of the Plus 15 to be shut down for a period of time.  The large and cumbersome HVAC ducting would have had to be removed by a mechanical contractor and a electricians would have had to move the cable trays with all of the live electrical wires running through them.  This work would have been disruptive to the public, noisy, time consuming and most important, unnecessary.

Revive Pipes Solution

Revive Pipe Restoration Inc was able to use existing access points in the system to install cured in place pipes (CIPP) in the deteriorated cast iron rainwater leaders coming from the roof of the Plus 15.  We worked in the evening to avoid any disruption to the heavy foot traffic experienced in the Plus 15 on a daily basis.  Revive Pipe’s solution avoided the costly and disruptive removal of a large section of HVAC components and electrical cable trays in the ceiling space.  The CIPP liners completely sealed the rainwater pipes and stopped all of the leaks permanently.

Revive Pipes Cured in Place Pipe (CIPP) Lining Services

Revive Pipes focus is on providing minimally invasive and disruptive solutions to our clients storm and sanitary drain pipe issues.  We can install Cured in Place Pipe (CIPP) liners in any type of drain pipe, but typically in commercial settings we are working with cast iron drain pipes.  Cast iron pipes are susceptible to cracking, corrosion and embrittlement.   We install permanent structural liners inside of cast iron pipes in all states of deterioration.
