Sewer Pipe Lining
Cracked, leaking, and deteriorated sewer pipes do not always require complete excavation and replacement. When the existing pipe still has enough structural integrity, sewer pipe lining may provide a durable trenchless solution that restores the interior of the line with significantly less digging.
RDZ Plumbing and Drains provides professional sewer pipe lining for residential, commercial, rental, and multi-unit properties throughout San Diego. Our team inspects the sewer line, evaluates the type and extent of damage, prepares the pipe, and determines whether lining is appropriate for the existing system.
A properly installed liner creates a new pipe surface inside the damaged sewer line, helping seal cracks, cover small gaps, reduce root intrusion, and restore dependable wastewater flow.

What Is Sewer Pipe Lining?
Sewer pipe lining is a trenchless repair method that installs a new liner inside an existing damaged pipe.
Instead of excavating and removing the entire sewer line, a flexible liner coated with resin is inserted through an existing access point. The liner is positioned against the interior wall of the old pipe and cured until it becomes a solid, durable pipe within the original line.
This method is commonly known as:
- Trenchless pipe lining
- Sewer relining
- Cured-in-place pipe lining
- CIPP lining
- No-dig sewer rehabilitation
- Pipe-within-a-pipe repair
Once cured, the liner creates a smooth interior surface that improves flow and isolates damaged areas of the original pipe.
When Is Sewer Pipe Lining Recommended?
Pipe lining may be suitable for sewer lines affected by cracks, small holes, corrosion, deteriorated pipe walls, leaking joints, minor root intrusion, small gaps between pipe sections, or repeated blockages caused by rough interior surfaces. It may also be recommended for aging cast-iron pipes, certain damaged clay pipes, and sewer lines with scale buildup after proper cleaning.
This method is often especially useful when pipes are difficult to access or located beneath landscaping, driveways, floors, or other finished surfaces.
Before pipe lining can be recommended, the sewer line must be thoroughly inspected and cleaned to determine its condition and confirm that the pipe is suitable for rehabilitation.
Not every damaged sewer line is a good candidate for lining. Pipes that are severely collapsed, badly misaligned, or extensively deformed may require trenchless replacement or traditional excavation instead.
