The power of one partner: Trelleborg’s integrated approach to pipe rehabilitation

The challenge: Aging infrastructure and a costly endeavor

The Solidarity Tower Co-op, a 26-story apartment building in the Canadian city of Windsor, Ontario, was facing a significant issue: a severely corroded vertical stack drain system. The cast iron pipes, ranging between 3 to 4 inches in diameter and varying in size throughout the building, had deteriorated over time.

The traditional solution – replacing the entire pipe system – would involve breaking through walls in multiple apartments, causing extensive disruption to residents, inflating costs, and potentially jeopardizing the building's structural integrity.

Faced with these challenges, Aqua Tech Solutions turned to Trelleborg for a long-term solution that would minimize both disruption and costs. Trelleborg’s expertise in seals and profiles and our extensive product portfolio offered the perfect combination of innovation and efficiency.

The solution: Leveraging Trelleborg’s comprehensive product range

Aqua Tech and Trelleborg devised a strategy to reline the building's vertical stack pipes without invasive demolition. The project involved installing a 100-foot liner per shot across 12 floors at a time, with each installation requiring the precise opening of 12 service connections after the liner had been cured.

To achieve these results, a diverse range of Trelleborg products were utilized. The solution combined multiple consumable materials, such as:

• ThermoLiner Stretch SL and MultiFlex Liner: Ensuring flexibility and durability for the varied pipe sizes
• UV Calibration Hose: Providing a perfect fit for curing processes
• RayCure UA Resin: Delivering a strong, long-lasting seal

Specialized equipment was also crucial to ensure the project’s success, including:

• Picote Maxi Miller: To thoroughly clean the pipes prior to relining, ensuring optimal adhesion of the new liners
• Inversion Drum: For efficient liner installation
• SpeedyLight UV LED Curing Unit: Offering rapid curing capabilities, which drastically reduced downtime and overall project duration
• Climbolino Micro Cutter: To accurately open service connections post-curing, restoring full functionality quickly

The results: A seamless experience

Utilizing our extensive product portfolio and cutting-edge technologies, we enabled the building to maintain full functionality while minimizing the typical costs, delays, and disruptions linked to conventional pipe replacement methods. This seamless execution not only safeguarded the structural integrity of the property but also ensured peace of mind for the building’s residents.

By delivering a full spectrum of high-performance products and integrated solutions, Trelleborg demonstrated its ability to tackle even the most complex challenges with precision and efficiency.
