What is Pipe Relining: A Brief Guide

Replacing pipelines does not have to be a challenge. Explore what pipe relining is, and understand what is pipe relining and how it works, its benefits, and more in the article below. Broken pipes and the first thought that comes rushing to the mind is a lot of related hard work, right from digging them up to patching or replacing the pipes. Not to mention how the piping infrastructure is not exactly something most are fond of revisiting, especially the one on the brink of overuse damage. However, there is a much trouble-free and straightforward solution to this piping situation – pipe relining done through experts like The Relining Company Australia. Let’s dig in and understand it better – 

What Is Pipe Relining?

Pipe relining is the process of repairing blocked, broken or cracked pipes without digging up the ground. It essentially follows a method of curing the pipes from inside using a special type of resin that, with time, cures to form another similar pipe(often stronger) inside the damaged one.

Since the insertion of the resin-saturated felt tube for resin impregnation in pipe relining follows an almost trenchless technology, the process hardly requires any digging. Fix your blocked and broken pipes with the latest pipe relining technology... More of its advantages are discussed further in the article.

How Is Pipe Relining Done?

Inspection – 

The process begins with the most obvious step – examining the pipe to find the damage and its severity. Though typically, to access the pipes, closed-circuit drain cameras are used, you may also find services employing the new electron leak location (FELL) equipment that allows much closer Inspection.

Cleaning and the second Inspection –

Resin cannot set well on blocked or unclean pipes, and therefore in this multiple-step process, the pipes are thoroughly cleaned. It follows the order of regular cleaning, removal of large blockages using robotic cutters, and high-pressure water jets. 

Once done, it is time for one final check to ensure that the pipes are all clean and ready. It also includes determining the length of the pipe and damage extent. 

The Process – 

In this main step, a custom felt liner and inflatable bladder that will match the pipe specifications are inserted, pulled into position, and inspected. Next, the liner, using compressed air, is inflated such that the resin sticks to the inner surface appropriately and entirely. 

The lining is either left to cure manually or accelerated with the help of hot water. You may also witness the use of UV radiation to ensure absolute hardness as the final step.

Deflating and final Inspection –

Once done, the bladder is deflated and removed. The step follows cutting the junction and inspection pits using robotic cutters, grinders, etc. At this point, you have a much stronger structure that will last for a long time. 

Besides the final Inspection using a closed-circuit drain camera, the service will also check the performance of the pipes to ensure the perfect completion of the task.

The benefits of pipe relining

Pipe relining is most evidently a better solution to the traditional drain repair systems. Below are some of the significant benefits pipe relining to prove the same –

No landscaping issues

Digging up the pipes is perhaps the most bothersome, detrimental, and costly step of the traditional process. Not to mention how it destroys the entire landscape, upheavals the surroundings, harms the flora of the place, and much more. 

But with pipe relining, none of it is an issue as it causes minimal disruption if any. 

Faster and safer

Pipe relining is a quicker process compared to digging trenches and replacing or repairing pipes. It also makes access to hard to reach areas much more manageable while reducing your exhaustion of the process.

But that’s not all. No digging or landscape alteration also directly implies increased safety on the ground for everyone from children to the elderly and even animals.

Durability and cost-effectiveness

Though a new pipe altogether may seem like a better idea, pipe relining has much better to offer with its stronger piping system approach that’ll last much longer. It will also help you cut down the cost of digging, replacing, filling up, loss of natural resources and flora, cost of labor, and more. 

If anything, pipe relining will only add resale and general value to the property. 


Though pipe relining is a long-term solution, certain factors such as small diameters, tricky bents, uneven cleaning, etc., can alter your experience and results. In the worst-case scenario, it can leave the pipes more susceptible to damage than before. 

Therefore, it is rather important to pick a reliable service that ensures each step is carried out perfectly. Happy Scrolling!
