Slip-Lining Sewer Pipe: A Modern Solution for Efficient Repairs

sewer pipe installation

Are you tired of dealing with constant sewer pipe issues that cause headaches and disruptions in your daily life? Worry no more as we introduce you to the revolutionary technique of slip-lining sewer pipes, a cutting-edge solution that can save you time, money, and a whole lot of stress.

Say goodbye to traditional excavation methods, and let's dive into the world of slip lining, where simplicity meets innovation, and your sewer pipe troubles become a thing of the past.

What is Slip Lining?

Imagine having your sewer pipes repaired with minimal digging, less mess, and faster turnaround times. Slip-lining could be the answer for you, providing a long-lasting, cost-effective, and environmentally friendly solution to rehabilitate damaged sewer lines.

Slip lining is simply inserting a smaller pipe into the existing damaged sewer pipe. This provides structural support and improves flow capacity without the need for extensive excavation.

Whether you are a homeowner or a business owner, this modern method is suitable for various applications and can effectively address a wide range of sewer issues.

When to Use Slip Lining for Sewer Pipe Repair

Slip lining can be used when excavation and replacement are not feasible or cost-effective. It is suitable for pipes with moderate damage, such as cracks, corrosion, or minor leaks.

It can also be used when the existing pipe is still structurally sound, and when repairing sewer pipes located under roads, buildings, or other structures where excavation is challenging.

Slip Lining Sewer Pipe: Understanding the Technique

Slip lining is a trenchless technology that involves inserting a new pipe, often made of high-density polyethylene (HDPE), into the existing damaged sewer pipe.

The new pipe is carefully "slipped" into place, following the path of the original pipe, effectively creating a new, structurally sound conduit within the old one.

This process is akin to giving your sewer line a new lease on life without the need for extensive excavation.

The Process: A Step-by-Step Guide

  • Initial Inspection: Before commencing sliplining, a thorough inspection of the damaged sewer pipe is conducted. This step helps in identifying the extent of the damage and any blockages that may hinder the slip-lining process.
  • Cleaning and Preparation: The existing sewer pipe is cleaned using high-pressure water jets to remove debris and obstructions. This ensures a smooth surface for the new pipe to slide onto.
  • Measurement and Pipe Selection: The dimensions of the new HDPE pipe are carefully measured to ensure a perfect fit inside the old pipe. The HDPE pipe is chosen for its durability, corrosion resistance, and long lifespan.
  • Insertion of New Pipe: The new HDPE pipe is inserted into the old pipe through existing access points or strategically created entry points. As the new pipe moves along, it displaces any blockages and takes on the shape of the old pipe.
  • Sealing the Joints: Once the new pipe is in place, the joints are sealed to prevent the infiltration of groundwater or tree roots, enhancing the pipe's longevity.
  • Testing and Approval: The newly lined sewer pipe undergoes rigorous testing to ensure it meets industry standards and can handle the flow of wastewater efficiently.
  • Restoration: Finally, any access points created during the process are properly sealed, and the surrounding area is restored to its original condition.

Advantages of Slip-Lining Sewer Pipe

Slip lining offers a plethora of benefits that make it a superior choice for sewer pipe repairs.


Slip lining reduces the need for extensive excavation, saving you money on labor and restoration costs.

Minimal Disruptions

Unlike traditional digging methods, slip lining minimizes disruptions to your property, preserving landscapes, driveways, and other structures.

Faster Repairs

Slip lining significantly reduces repair time, allowing you to get back to your daily routine in no time.


The new HDPE pipe is highly durable and resistant to corrosion, ensuring a long-lasting solution.

Increased Flow Capacity

The smooth interior of the HDPE pipe improves flow capacity, reducing the risk of future blockages.


Slip lining is environmentally friendly, as it reduces the carbon footprint associated with extensive excavation and transportation of debris.

Disadvantages and Limitations of Slip Lining

Potential reduction in pipe diameter:

Since the new pipe is inserted into the old pipe, there is a change that the new pipe will be slightly smaller in diameter.

Not suitable for severely damaged or collapsed pipes:

Sewer pipe slip lining is only suitable for pipes with moderate damage, such as cracks, corrosion, or minor leaks.

Challenges with curved or bent pipes:

This technique works best with straight pipes that do not have any sort of curves or bends in them.

Longevity of Slip Lining

Slip lining has transformed the way we approach sewer repairs. When it comes to how long slip lining can last, there are various factors involved. These include the quality of materials used, the condition of the existing pipe, and the surrounding environment.

All in all, slip lining can last 50 years or more!

Cost-effectiveness of Slip Lining

Compared to traditional excavation and replacement methods, slip lining is often more cost-effective due to reduced labor and material requirements.

Professionals You Can Trust

I hired Pro Sewer Repair to replace my sewer line. Their estimate was much more reasonable then Pro Sewer fixed a large break in our sewer line where it joined the city mainline. They handled this large job effectively, cost-efficiently, and were great to work with. Jamie and Rob were awesome to work with on scheduling and responsive to questions, and the team (Jason and James) did a great job with the work. Would use them again and will recommend to friends.
