Underground Conduit Problems? You May Not Have to Dig It Up.

When underground electrical or telecommunications conduits fail, replacement can mean excavation, demolition, downtime and major disruption.

CIP-Conduit® offers another option.

Flow-Liner's CIP-Conduit rehabilitates existing underground conduits from the inside, creating a new seamless liner without removing the existing conduit.

It can help address:

💧 Water infiltration
🧱 Concrete-filled conduits
🔧 Punctured or damaged conduit
🟤 Deteriorated Orangeburg
↪️ Conduit runs with multiple bends
📏 Full-run or partial rehabilitation

From military installations and data centers to utilities, government facilities and telecommunications networks, trenchless conduit rehabilitation can keep critical infrastructure moving—without tearing up the surrounding structure.

And we've done it in some pretty challenging places.

🏛️ Pinnacle Project Series: Cannon House Office Building

When a historic building has a plumbing problem, excavation isn't an option.

The Cannon House Office Building in Washington, D.C.—the oldest congressional office building in the United States—developed leaks in two roof drain lines, allowing water to infiltrate the walls of this iconic structure.

The challenge? Each 5" roof drain ran approximately 90 feet with multiple bends, including a sweeping 90°, a 45°, and a connection into a wye before dropping five stories to the basement. Restoring the system required a solution that could navigate complex pipe geometry while preserving the building's historic integrity.

💡 The Solution
A Flow-Liner Certified Installer successfully rehabilitated both roof drains using 5" Flow-Liner Flex Liners and Cured-In-Place Pipe (CIPP) technology. The flexibility of the liner was essential for negotiating the multiple bends and providing a durable, structural repair—without demolition or disruption to the historic building.

Projects like this demonstrate how trenchless technology can solve some of the industry's most challenging pipe rehabilitation projects while protecting the structures that matter most.

Only Pay for What You Need
Not every job calls for a full roll of liner—and forcing one to fit can mean wasted material, tied-up cash, and unnecessary storage headaches.

That’s why Flow-Liner offers CIPP liners by the foot, with no minimum order requirements.

Whether you're tackling a short residential repair, handling spot work, or just beginning to explore trenchless solutions, you can order exactly what your project needs—no excess, no guesswork.

We also manufacture custom transitional liners in any material or size, giving you even more flexibility when dealing with complex or changing pipe conditions.

As a U.S.-based manufacturer, we’re able to offer the flexibility many suppliers simply can’t. Our goal is to make CIPP more accessible, especially for contractors who want to grow their capabilities without committing to large upfront inventory purchases.

This approach doesn’t just reduce waste—it helps you stay competitive, responsive, and efficient on every job.

Need 12 feet? 40 feet? 85 feet? You decide.

When Upper Arlington Lutheran Church faced serious issues with their aging underground HVAC duct system, they turned to Flow-Liner® for a solution. Years of deterioration and groundwater infiltration were impacting performance and indoor air quality—but excavation wasn’t the answer.

Using our trenchless CIP-Duct® system, an ambient cure 12-inch liner was installed across two sections (40’ and 60’), including a 45° bend, with 10–12 registers reinstated. The entire project was completed in just two days—restoring structural integrity and sealing out infiltration for good.

“I thought I’d never get someone to even look at this… one call to a Flow-Liner Installer changed everything. The finished job fixed all the issues we were having.” – Maintenance Director
