What Happens During a CIPP Lining Installation? A Step-by-Step Visual Guide

A damaged sewer line can quickly turn into a big problem if left unchecked. When pipes crack, corrode, or collapse, water flow is restricted, and sewage can back up, causing property damage. That’s where trenchless pipe lining comes in. We get right to the source of the issue without tearing up your yard or walls, restoring your pipes efficiently and effectively. If you’re looking for professional pipe lining in Stafford, VA, we’re here to guide you through the process and show how it all works.

Inspection and Assessment

We start by sending a specialized sewer camera down the line to get a complete view of the pipe’s interior. This is not just a cursory look; our trenchless pipe lining team records video of every crack, offset joint, or buildup inside your sewer pipe. As one of the leading pipe lining companies in Northern Virginia, we analyze these images to map out the exact length of pipe that needs repair. 

Every decision in a CIPP lining installation depends on accurate data from this inspection.

Cleaning the Pipe

Before the liner goes in, we need a completely clean surface. That means high-pressure water jetting to remove grease, roots, and debris that could prevent proper adhesion. Even minor buildup can compromise the integrity of the cured in place pipe service, so we take this step seriously. A clean pipe ensures the liner molds perfectly to the interior and forms a solid, durable barrier against leaks.

Inserting the Liner

Next, we prepare the CIPP lining itself. It’s a flexible tube impregnated with a resin designed to harden inside your pipe. Using air or water pressure, we carefully insert the liner into the damaged section. The liner inflates and presses tightly against the pipe walls. This is where the trenchless pipe lining magic happens: no excavation, no heavy machinery inside your property, just a seamless pipe inside the old pipe.

Curing the Liner

Once in place, we cure the resin using heat or UV light. This transforms the liner into a rock-solid, seamless pipe that fits perfectly inside your old sewer line. The hardened liner restores strength and prevents leaks, cracking, or corrosion for decades. Our sewer pipe lining approach provides long-term reliability while keeping your property intact.

Final Inspection and Flow Testing

After curing, we run the camera through the pipe again. This step ensures that every inch of the liner is smooth, properly sealed, and free of wrinkles. We also test water flow and pressure to confirm that the sewer line is operating perfectly.
