Living in an aging apartment building often brings the constant fear of leaks, corrosion, and catastrophic pipe failures. Rehabilitating domestic water stacks (both hot and cold) doesn’t have to be a demolition nightmare anymore!
SIPP (Spray-In-Place Pipe) technology, championed by industry leaders like Relining Group, is the rapid, modern, and trenchless solution for multi-story residential infrastructure.
How the SIPP Epoxy Lining Process Works:
- Advanced Cleaning: The old stack is mechanically and thermally cleaned to remove buildup and rust, preparing a clean inner surface.
- Resin Application: A specialized, potable water-certified (depending on application) epoxy resin is robotically sprayed onto the entire inner surface of the pipe.
- New Pipe Formation: The resin cures quickly, creating a seamless, non-corrosive, and self-supporting lining. Essentially, a new structural pipe is formed right inside the deteriorated original one.

Why Choose SIPP for Water Stack Rehabilitation?
- Zero Demolition & Disruption: No need to tear down walls, bathrooms, or kitchens. The work is executed minimally invasively, usually from the rooftop down to the basement.
- 50+ Year Lifespan: The durable epoxy lining provides superior resistance to corrosion and future scale buildup.
- Speed and Efficiency: Stacks are rehabilitated in a matter of days, not weeks, minimizing water service downtime for residents.
- Health & Flow Improvement: Eliminates the risk of contaminants like rust and lead leaching into the water, while the smooth surface improves water flow (hydraulics).
SIPP is more than a repair; it’s a complete structural renewal of your interior water network. Discover how to eliminate your old pipe worries for good!
