Pipe Relining

Pipe Relining is One of the Drain Pipe Repairs We Do

Drain pipe issues are a common headache for homeowners and businesses alike. From leaks and blockages to root intrusion and corrosion, the problems can be both frequent and frustrating. Traditional pipe repair methods often involve extensive excavation, leading to significant disruption and cost. Enter pipe relining: a modern, efficient solution that addresses these issues with minimal fuss. In this article, we’ll explore what pipe relining is, its benefits, and why it’s becoming the preferred method for repairing drain pipes.

What is Pipe Relining?

Definition and Process

Pipe relining is a trenchless pipe repair method that involves inserting a new lining inside the existing damaged pipe. This creates a pipe within a pipe, restoring the function and integrity of the drainage system without the need for extensive digging.

Comparison to Traditional Pipe Repair Methods

Traditional methods often require digging up the old pipes, which can be disruptive and costly. Pipe relining, on the other hand, is less invasive and quicker, making it an attractive alternative.

The Benefits of Pipe Relining

Minimal Disruption

One of the standout benefits of pipe relining is that it causes minimal disruption. There’s no need to dig up your garden, driveway, or floors, which means your daily life or business operations can continue with little interruption.


While the upfront cost of pipe relining can be comparable to traditional methods, the long-term savings are significant. There’s less labour involved, and because the new lining is highly durable, it reduces the need for future repairs.

Longevity and Durability

The materials used in pipe relining are designed to last. They can withstand root intrusion, corrosion, and other common pipe problems, ensuring that your pipes remain in good condition for many years.

How Pipe Relining Works

Initial Inspection

The process begins with a thorough inspection of the pipes, often using CCTV cameras to identify the extent of the damage and any blockages.

Cleaning the Pipes

Next, the pipes are cleaned to remove any debris, roots, or blockages. This is typically done using high-pressure water jets or mechanical cutters.

Inserting the Lining Material

Once the pipes are clean, a flexible lining material coated with resin is inserted into the damaged pipe. This lining is then inflated, pressing it against the pipe walls.

Curing Process

The resin is then cured, either using hot water, steam, or UV light, hardening the lining and creating a new, solid pipe within the old one.

Types of Pipe Relining Materials

Epoxy Resin

Epoxy resin is commonly used for its strong adhesive properties and durability. It’s suitable for a wide range of pipe materials and sizes.

Polyester Resin

Polyester resin is another option, known for its cost-effectiveness and suitability for certain pipe types. It’s often used in less demanding applications.

Vinyl Ester Resin

Vinyl ester resin offers excellent resistance to corrosion and chemicals, making it ideal for industrial applications where harsh substances are present.

When to Consider Pipe Relining

Signs Your Pipes Need Relining

Common signs that your pipes may need relining include drain blocked frequently, slow drainage, bad odours, and water damage in unexpected places.

Common Issues Addressed by Relining

Pipe relining can address a variety of issues, including cracks, leaks, root intrusion, and corrosion, restoring the pipes to a like-new condition.

Cost of Pipe Relining

Factors Influencing Cost

Several factors can influence the cost of pipe relining, including the length and diameter of the pipes, the extent of the damage, and the accessibility of the pipes.

Comparing Costs with Traditional Methods

While the initial cost of pipe relining can be similar to traditional methods, the long-term savings in reduced labour and less frequent repairs make it a cost-effective solution.

Advantages Over Traditional Methods

Less Invasive

Traditional methods often require significant excavation, which can be disruptive and damaging to property. Pipe relining, however, is trenchless and much less invasive.

Faster Completion Time

Because there’s no need for extensive digging, pipe relining can be completed much faster than traditional repairs, often in a matter of hours.

Environmental Benefits

Pipe relining is also more environmentally friendly, as it reduces the need for excavation and the associated environmental impact.

Pipe Relining for Different Types of Properties

Residential Properties

Homeowners can benefit from pipe relining to address common drainage issues without the disruption of digging up gardens or driveways.

Commercial Properties

Businesses can avoid downtime and disruption by choosing pipe relining, ensuring their operations continue smoothly while repairs are carried out.

Industrial Properties

Industrial sites often have complex drainage systems that can benefit from the durability and chemical resistance of pipe relining materials.

The Pipe Relining Process in Detail

CCTV Drain Survey

A CCTV drain survey is conducted to assess the condition of the pipes and pinpoint the location and extent of the damage.

Pipe Cleaning Techniques

The pipes are cleaned using high-pressure water jets or mechanical cutters to remove any debris, roots, or blockages.

Installing the Liner

A flexible liner coated with resin is inserted into the pipe and inflated, pressing it against the walls of the existing pipe.

Quality Checks and Testing

Once the resin has cured, quality checks and testing are performed to ensure the new lining is secure and the pipe is fully functional.

Challenges in Pipe Relining

Access Issues

In some cases, access to the pipes can be challenging, requiring additional planning and equipment.

Severe Pipe Damage

If the pipes are severely damaged or collapsed, pipe relining may not be possible, and traditional excavation methods may be required.

Material Limitations

While pipe relining is suitable for most pipes, some materials or pipe configurations may present challenges.

Innovations in Pipe Relining Technology

Advances in Materials

New materials are continually being developed, offering improved durability, flexibility, and chemical resistance.

Improved Curing Methods

Advances in curing methods, such as UV light curing, have made the pipe relining process faster and more efficient.

Enhanced Inspection Tools

Modern inspection tools, including high-definition CCTV cameras and real-time data analysis, provide more accurate assessments of pipe conditions.

Choosing a Professional for Pipe Relining

Qualifications and Certifications

When choosing a professional for pipe relining, look for qualifications and certifications that demonstrate their expertise and reliability.

Experience and Reputation

Experience and reputation are key factors to consider. Look for professionals with a proven track record of successful pipe relining projects.
