What to Expect During Your Sewer Pipe Lining Installation

Pipe lining is a trenchless sewer repair method that involves no digging. It is a less expensive alternative to a complete sewer replacement and can help repair damaged pipes without causing damage to your yard or driveway.

The process involves inserting a new epoxy-saturated pipe tubing into the sewer line. The tubing is then inflated and cured with hot air, steam or blue light LED technology to create a new seal.


Before your sewer pipe lining installation begins, we need to clean the existing drain pipes. This will remove the scale, calcite, and other debris built over time.

It is essential to clean the pipes before a liner is put in because these contaminants can cause the epoxy lining to fail prematurely or not adhere properly.

We use special jets and tools to clean the pipes, removing the buildup of sediment and roots. This ensures that the epoxy lining will stick to the host pipe and seal off the underlying structure of the sewer line.

Once the pipes are cleaned, we will insert the CIPP liner into the existing pipe. This can be done by inversion (blown into the current sewer line) or by positioning it manually, depending on the situation.

Unlike trenching, this method involves no digging or excavation and saves on material costs. It also is less disruptive and can be completed in half the time. This makes it an ideal solution for any home or business experiencing problems with its drains.

Inserting the Liner

To install a pipe liner, you must have a solid sewer pipe to insert the new liner into. Many Pittsburgh homes built before the 1980s still have old clay tile sewer lines. They could be a better candidate for sewer liner installation since these pipes are often weakened and need mechanical seals to hold them together.

Thankfully, other trenchless sewer repair methods can replace your sewer pipes without excavation in your yard. These include spray lining and brush coating.

These techniques can save you up to 40% off the cost of traditional digging and tearing out your old sewer pipes. They also require no yard destruction, sidewalk or trees and can finish the job in just a few hours.

Once your sewer line is repaired using one of these trenchless solutions, you can expect to see a significant improvement in how your system functions. This can reduce water and sewer usage, eliminate the need for costly drain cleanings, and increase your home’s value and curb appeal.

Inflating the Liner

During sewer pipe lining installation, crews insert a waterproof sleeve saturated with epoxy resin. They then inflate it and allow it to cure inside your pipe. This process relines your damaged sewer line and creates a new, seamless “pipe-within-a-pipe” that will last for decades without the need to replace it.

CIPP is one of several trenchless repair methods that can be used to fix sewer and drain lines that are cracked or leaking. This minimally invasive technique is less expensive and takes less time than traditional sewer line replacement.

It also prevents soil and plant damage in the area. This procedure requires specialized equipment and techniques that ensure little to no destruction of your property.

There are many advantages to sewer pipe lining that can benefit your home and your family. Sealing cracks, leaks, and damage to your pipes enables your plumbing system to operate more efficiently. It can be less costly than replacing your sewer and drain lines and offers a lasting solution to sewer problems.

Curing the Liner

Curing your lining into a permanent state is one of the essential parts of your trenchless pipe-lining process. This will help prevent the liner from crumbling and causing further damage to your sewer pipes and home or building.

CIPP (cured-in-place-pipe) is one of the most widely used methods of rehabilitating deteriorated and leaking gravity sewers in North America and around the globe. It is a jointless, seamless pipe lining within your existing pipes formed by inserting and running a felt tube saturated with epoxy resin.

It is typically cured into place by exposing the liner to heat or UV light, which hardens the resin. This process is designed to restore your pipe’s structural integrity and seal out infiltration while avoiding the more costly alternatives of digging and replacement.

Several different curing processes are available. Depending on your requirements, you can choose from ambient, hot, steam, and UV LED curing. Each method has its benefits and limitations. Choosing the right plan for your project is critical to ensuring a successful repair.

Final Inspection

The final inspection is often a walk-through of the completed project that can take place from a few hours to five days before settlement. The inspector will look for egress requirements, electrical violations, and safety clearances.

An electrical plan violation is one of the most common errors during a final inspection. This could be as simple as moving or deleting an outlet that is unnecessary or not in the proper location.

CIPP is an excellent and cost-effective way to fix sewer pipe issues, but all work must be done correctly. The final inspection will help to ensure that the work was completed in compliance with all building codes and will allow you to verify the quality of the CIPP liner.

The installation process itself will only take a few hours of work. During this time, the installer will insert new epoxy-saturated pipe tubing into the existing pipes. The tubing is then inflated and cured with either hot air, steam, or blue light LED technology. This creates a seal in the line that can last for decades!
