Updated: Jul 5, 2023

pipe lining and pipe relining

Pipe lining, also known as pipe relining, has emerged as an efficient and cost-effective method for rehabilitating damaged sewer piping. Imagine waking up to a leaking sewer pipe in your home. The thought of water damage and costly repairs can be overwhelming. However, the replacement of conventional sewer pipes is no longer the only option due to technological improvements. The ins and outs of pipe lining, its advantages, and the reasons it has become a popular option for many households and companies will all be covered in this article. We at Stillorgan Drain Cleaning are at your service 24/7 for you required needs.

Introduction to Pipe Lining

introduction to pipe lining

Pipe lining, also known as cured-in-place pipe (CIPP) lining, is a trenchless technology used to rehabilitate damaged sewer pipes without the need for extensive excavation. It involves creating a new pipe within the existing one by inserting a flexible liner coated with a special epoxy resin.

Understanding the Pipe Lining Process

The pipe lining process typically involves the following steps:

Inspection and Cleaning

Using cutting-edge technology like closed-circuit television (CCTV) cameras, a complete inspection of the sewer pipes is carried out before the lining procedure starts. This helps identify the extent of damage and determine the suitability of pipe lining for sewer piping. Once the pipes are inspected, they are cleaned using high-pressure water jetting or mechanical methods to remove debris and corrosion.

Liner Installation

After the pipes are cleaned, a liner saturated with an epoxy resin mixture is inserted into the damaged sewer pipe. The liner is inflated and pressed against the walls of the existing pipe. This allows the resin to bond and form a tight-fitting, durable new pipe inside the old one.

Curing and Final Inspection

Depending on the kind of resin used, the liner is then cured after being installed using either heat or UV radiation. This process hardens the resin, creating a structurally sound sewer pipe that is resistant to corrosion and leaks. After curing, a final inspection is conducted to ensure the integrity of the new pipe.

Advantages of Pipe Lining

advantages of pipe lining

Pipe lining offers several advantages over traditional pipe replacement methods when it comes to sewer pipes:


Pipe lining is a cost-effective solution for sewer pipe repair and patching compared to traditional pipe replacement, as it eliminates the need for extensive excavation and associated costs. It reduces labor and material expenses while minimizing disruption to the property and its occupants.

Time Efficiency

The pipe lining process is typically faster than traditional pipe replacement for sewer pipes. The project can be finished faster because there isn't a requirement for considerable excavation. This is particularly beneficial for businesses and homeowners who want to minimize downtime.

Durability and Longevity

The new sewer pipe created through pipe lining is highly durable and resistant to corrosion, cracks, and leaks. It is durable and frequently has a lifespan of at least 50 years. This longevity ensures long-term savings and peace of mind for property owners.

Preservation of Landscape

One of the significant advantages of pipe lining for sewer pipes is that it preserves the landscape surrounding the pipes. Traditional pipe replacement involves digging trenches, which can damage lawns, driveways, and other outdoor areas. With pipe lining, minimal disruption occurs, and the landscape remains intact.

Comparing Pipe Lining with Traditional Pipe Replacement

Pipe lining offers distinct advantages when compared to traditional pipe replacement methods for sewer pipes. Let's look at some key differences between the two:

Excavation Requirements

Traditional pipe replacement for sewer pipes involves extensive excavation to access the damaged pipes. This can be disruptive and costly, especially in urban areas or properties with complex layouts. Pipe lining, on the other hand, requires minimal excavation, often limited to small access points.

Cost and Time

Traditional pipe replacement for sewer pipes is labor-intensive, which makes it more expensive and time-consuming.. Pipe lining offers cost savings by reducing labor and material expenses, and its efficient process ensures a quicker turnaround time.

Environmental Impact

Pipe lining is an environmentally friendly solution for sewer pipe repair and patching as it minimizes excavation and reduces waste. Traditional pipe replacement can generate significant amounts of construction debris and disturb natural habitats. Pipe lining contributes to sustainability by preserving the environment.

Factors to Consider Before Opting for Pipe Lining

Factors to Consider Before Opting for Pipe Lining

While pipe lining offers numerous benefits for sewer pipes, certain factors should be considered before choosing this method:

Pipe Condition and Suitability

Pipe lining is suitable for a variety of sewer pipes, including clay, cast iron, PVC, and concrete. However, the condition of the pipes plays a crucial role. Severely collapsed or heavily damaged pipes may require traditional replacement instead of lining.

Access Points

Pipe lining for sewer pipes requires access points for inserting the liner and curing the resin. The availability and location of these access points should be assessed to determine the feasibility of pipe lining in a particular scenario.

Pipe Diameter and Length

Pipe lining can be performed on sewer pipes of different diameters and lengths. However, larger diameter pipes may require additional considerations during the lining process. The length of the damaged pipe also affects the overall cost and time required for pipe lining.

Common Applications of Pipe Lining

Pipe lining has found applications in various sectors, including residential, commercial, and industrial settings. Some common applications for sewer pipes include:

  • Sewer line rehabilitation and repair

  • Stormwater pipe repair

  • Trenchless pipe replacement

  • Pipe relining in high-rise buildings

  • Industrial sewer pipe repair and maintenance

Pipe Lining: A Sustainable Solution

Pipe Lining: A Sustainable Solution

Pipe lining offers a sustainable solution for addressing sewer pipe damage and deterioration. By rehabilitating existing pipes instead of replacing them entirely, it reduces the consumption of new materials and minimizes the carbon footprint associated with traditional pipe replacement methods.


In conclusion, pipe lining or pipe relining provides an efficient and cost-effective alternative to traditional sewer pipe replacement. With its trenchless technology, durability, and minimal disruption, it has become a preferred choice for many homeowners and businesses in need of sewer pipe repair and patching. The benefits of pipe lining for sewer pipes include cost savings, time efficiency, landscape preservation, and environmental sustainability. Before opting for pipe lining, it is essential to assess the sewer pipe condition, access points, and diameter to ensure its suitability. By embracing pipe lining, property owners can enjoy long-lasting, reliable sewer pipes without the hassles of extensive excavation.
