The Cured-in-Place Pipe (CIPP) industry is evolving. More and more installers are choosing to vertically integrate their operations, moving away from relying solely on third-party tube and liner suppliers.
Instead of sourcing finished tubes, resin, and other supplies from a single provider, today’s forward-thinking CIPP companies are bringing production in-house. With modest investment in fabrication equipment, they’re gaining more control over quality, reducing lead times, and improving margins.
But to succeed in this transition, one component is non-negotiable: access to reliable, high-performance coated nonwoven felt — the foundation of every CIPP liner.

Why More CIPP Installers Are Making Their Own Liners
Bringing liner manufacturing in-house unlocks several advantages:
-
Faster turnaround without waiting on outside suppliers
-
More control over quality and customization
-
Improved profit margins by owning more of the process
However, it all starts with the right base materials. That’s where we come in.
