Sewer pipe lining, a cornerstone of modern plumbing maintenance, offers a non-invasive solution to repairing damaged sewer lines. This innovative technique, also known as Cured-In-Place Pipe (CIPP) lining, involves the insertion of a resin-saturated liner into existing pipes, which is then cured to form a new, seamless pipe within the old one. The process is a preferred method for domestic and commercial properties.

Understanding Sewer Pipe Lining

The sewer pipe lining process begins with a thorough inspection of the existing pipeline, often using advanced camera technology to find issues such as cracks, leaks, and blockages. This initial step makes sure that the exact condition of the pipe is understood, allowing for a bespoke lining solution.

Once the inspection is complete, the next stage involves cleaning the old pipe. Techniques such as hydro jetting are used to remove debris, ensuring the liner can adhere smoothly to the pipe’s interior. This preparation is important for the lining’s longevity and effectiveness.

The Lining Process

The core of the sewer pipe lining technique involves the preparation and insertion of the epoxy-saturated liner. This liner, often made from durable materials like fibreglass or polyester, is carefully impregnated with a specially formulated epoxy resin. Through an inversion process using air pressure or water, the liner is then inserted into the damaged pipe, perfectly moulding to its interior.

Curing the liner is the final, critical step, transforming it from a flexible tube to a solid, robust pipe. This can be achieved through ambient curing, hot water, steam, or increasingly popular, UV light technology, each method ensuring the liner bonds securely, sealing off any previous damage.

Advantages of Sewer Pipe Lining

The benefits of sewer pipe lining are many. It eliminates the need for extensive digging, preserving landscapes and structures above the pipes. This trenchless approach not only saves time but significantly reduces the cost and environmental impact thats come with traditional pipe repair methods.

Moreover, the seamless nature of the lined pipe greatly reduces the risk of future leaks and blockages, offering an enhanced flow compared to older, jointed pipe systems. The durability of the materials used in lining ensures a long-lasting solution, often extending the life of the sewer system by several decades or even more.

Case Studies and Practical Applications

AJS Environmental has successfully implemented sewer pipe lining in various challenging scenarios, showing the versatility and effectiveness of this method. From complex urban environments to sensitive natural landscapes, the adaptability of sewer pipe lining has proven invaluable. Detailed case studies, such as the UV pipe lining project at a local school and the cost-effective drain pipe relining in Basildon, demonstrate the practical applications and tangible benefits of this innovative technique. These projects highlight the company’s commitment to providing eco-friendly, durable solutions for sewer maintenance challenges.


Looking to the Future

As we look towards the future of sewer maintenance, it’s clear that sewer pipe lining will continue to play a pivotal role. With ongoing advancements in technology and materials, the method is set to become even more efficient, eco-friendly, and adaptable to a wide range of repair scenarios.

For homeowners, municipalities, and businesses alike, staying informed about these developments is key to making informed decisions about sewer maintenance. By choosing advanced sewer pipe lining solutions, we can make sure the longevity and reliability of our sewer systems while minimising environmental impact and disruption to our daily lives.


In conclusion, sewer pipe lining represents a significant leap forward in the way we approach sewer maintenance. With its numerous benefits, including efficiency, cost-effectiveness, and environmental friendliness, it’s a solution that not only addresses the immediate needs of today’s sewer systems but also lays the groundwork for a more sustainable and resilient infrastructure in the future.
