The Technology

Understanding the science behind trenchless pipe rehabilitation.

01 Inspection & Cleaning

Before any lining can occur, the host pipe must be thoroughly inspected and cleaned. We use high-pressure water jetting and mechanical chains to remove roots, scale, and debris. This ensures the new liner bonds perfectly to the host pipe.

Tech Note: We use self-leveling CCTV cameras to map every inch of the pipe before proceeding.

02 Liner Impregnation (Wet Out)

A felt or fiberglass liner is custom-measured for your pipe. We then impregnate (“wet out”) this liner with a specially formulated epoxy resin. The resin is rolled into the liner to ensure 100% saturation and uniform thickness.

03 Inversion & Inflation

Using compressed air or water pressure, the resin-saturated liner is inverted (turned inside out) into the existing pipe. This process presses the resin-coated side firmly against the walls of the old pipe, filling cracks and bridging gaps.

04 Curing

Once in place, the liner is held under pressure while it cures. Depending on the resin system, this can be done at ambient temperature or accelerated with hot water or steam. The result is a hard, structural pipe.

05 Reinstatement & Final Inspection

If there are branch lines connecting to the main pipe, we use a robotic cutter to reopen them from the inside. Finally, a post-lining video inspection confirms the quality of the installation.

 Trustindex verifies that the original source of the review is Google. John and his team at Trenchless Maine were here at 7am and finished in under 4 hours  installing a 10 foot liner into our drainage pipe seen in the photos. They were very friendly and very efficient and very knowledgeable, explaining what they had done in detail and answering all the questions I had. I highly, highly recommend using their services throughout Maine. They literally saved us thousands of dollars and extended the life of our plumbing by 50 years! Thank you Trenchless Maine.

 Trustindex verifies that the original source of the review is Google. I was worried about the cost of trenchless repairs, but the team at Nuflow broke everything down clearly. The process was quick, non-invasive, and the results were immediate. Our old cast iron pipes in Corinna are now lined and working like new.

Frequently Asked Questions

How long does the liner last?

Our liners have a design life of 50+ years, which is comparable to or better than new PVC pipe. They are independently tested to meet ASTM F1216 standards for structural integrity.

Will it reduce the flow of my pipe?

While the diameter is slightly reduced (typically by 4-6mm), the smooth surface of the epoxy liner actually improves flow characteristics (coefficient of friction) compared to rough concrete, clay, or cast iron. In many cases, flow capacity actually increases.

Is it safe for the environment?

Yes. Once cured, the epoxy is completely inert and safe. It does not leach chemicals into the soil or water table. Plus, by avoiding excavation, we significantly reduce carbon footprint, heavy machinery usage, and landfill waste from old pipe disposal.

Can you line through bends?

Absolutely. Our flexible liners are designed to navigate 22, 45, and even 90-degree bends without wrinkling or losing structural integrity. We can also line through diameter transitions (e.g., 4″ to 6″ pipes).

How much does it cost compared to digging?

While the upfront cost can be comparable to excavation, trenchless repair is often 30-50% cheaper when you factor in the restoration costs. You won’t need to pay to repave your driveway, replant your garden, or rebuild your porch.
