What Is Pipe Relining and How Does It Work? Everything You Need to Know

If you want an easy and quick fix for repairing your pipes at an affordable cost, then pipe relining will be ideal for you. Now you may ask, what is pipe relining? Pipe relining is a method of repairing damaged pipes without excavating the ground. This process is done by inserting a flexible, durable lining into the damaged pipelines. The lining is then inflated and left to harden, creating a new, seamless pipe inside the old one. 

Pipe relining eliminates the need to excavate the ground, which can be expensive and time-consuming. It also causes minimal disruption to the surrounding area and can often be completed in a single day.  

When Should I Consider Pipe Relining? 

Instead of replacing the whole damaged pipes, the technique of pipe relining includes fixing broken lines from the inside. Due to the fact that this procedure is less intrusive and more affordable than the traditional method of pipe replacement, it is becoming more and more popular among homeowners and property managers.  

When you detect a drop in water pressure or flow, it may be the first indication that pipe relining is required. Numerous problems, such as pipe breaks, leaks, or obstructions, may be to blame for this. Consider pipe relining if you find that the water is not flowing as swiftly as it is supposed to or that the water pressure is low. 

You may also need pipe relining if you discover water leaks or damage in your house or other property. This may be brought on by rusted or broken pipes and no longer able to hold water adequately. It’s crucial to get your pipes checked for damage or leaks and to think about pipe relining as a possible remedy. 

If you detect a foul odour emanating from your pipes, it may also be a sign that pipe relining is essential. Over time, waste and debris accumulated in the pipes may be the reason for this. It’s a good idea to get your pipes checked out and think about pipe relining as a possible remedy if you detect an unpleasant odour emanating from them. 

Finally, thinking about pipe reline solutions as part of your pre-sale preparations if you want to sell your house or other property is a good idea. This will guarantee that your pipes are in excellent shape and won’t present any problems for prospective purchasers. Pipe relining may also increase the value of your house or other property. 

In conclusion, pipe relining is a fantastic way to fix broken pipes without replacing them, which would be expensive and disruptive. Pipe relining may not always be the best option, therefore, it’s crucial to know when to take it into account. It’s a good idea to get your pipes checked out and think about pipe relining as a possible remedy if you experience any of the problems mentioned above. 

Pipe Relining Process 

The process of sewer pipe relining begins with a thorough inspection of the damaged pipe. This inspection is typically done with a drain camera inserted into the pipe. This allows the technician to see the extent of the damage and determine the best course of action.  

Once the inspection is complete, the technician will clean the damaged pipe to ensure no debris or buildup could prevent the lining from adhering properly. The grease and oils are removed from it by utilising a hydro-jetter, which delivers water at very high pressure. Due to the amount of residue in the pipe, the resin would not attach without this.  

Incorrect execution of this task might result in uneven linings in the freshly constructed pipe. 

The lining materials are put together after the pipe is unquestionably clean enough. The liner is put into a calibration tube, which pulls it out when curation is required. Typically, fibreglass or polyester is used to make the calibration tube. The two-part epoxy resin is then thoroughly combined. 

It is crushed in an inversion trailer to guarantee that the epoxy gets to every fibre in the liner. The liner may then be stored in an ice bucket to keep it from hardening before it is used. To make the resin firm, it must be cured. Finally, the tube is exposed to ultraviolet radiation to finish the curing process. 

The lining procedure begins when the liner is put into the inversion tank. Epoxy is injected into the damaged pipe using an upstream access point. 

The liner is coated with a resin that will harden when it comes into contact with air. The liner is then inflated, pushing it against the walls of the damaged pipe. This ensures that the pipe has been properly adhered to. 

Once the liner is in place, it is left to harden for a while. This can take anywhere from a few hours to a few days, depending on the type of material used and the size of the pipe. Once the liner has hardened, it forms a new, seamless pipe inside the old one. This new pipe is just as strong and durable as traditional pipe and can last for many years. 

Pros of Pipe Relining 

Minimal excavation 

Pipe relining is a trenchless pipe repair method, meaning it does not require excavation. This is a significant advantage as it eliminates the need for heavy machinery and reduces the amount of disruption to your property. 

Faster repair time 

Pipe relining is a relatively quick process compared to traditional pipe repair methods. This is because the relining material can be inserted into the pipe without the need for excavation. 


Pipe relining is a cost-effective solution as it eliminates the need for excavation and the associated costs. It also extends the life of the pipes, reducing the need for future repairs. 

Improved flow 

Pipe relining can improve the flow of water and sewage through the pipes. This will result in better performance and reduced risk of blockages. 

Cons of Pipe Relining 

Limited Application 

Pipe relining is not suitable for all types of pipes and conditions. It is typically used for smaller-diameter pipes and is not recommended for pipes with severe damage or deformities. 

Removal Of Pipe Lining Is Difficult 

Epoxy resin pipe lining is said to be permanent. Once implemented, it’s quite tricky to remove. 

Issues with Pipe Lining When Installed Inadequately 

Future problems will arise if the installation procedure is not carried out correctly. Poor installation may cause liners to slide or shrink when it comes to pipelining, which will, among other things, lead to pressure and a drastically reduced flow capacity.  

How Long Will Pipe Relining Last? 

Pipe relining lasts for a long time, without a doubt. Generally speaking, all liners come with a reasonable 10-year installation guarantee. The pipe relining service that LCL Plumbing & Drainage provides lasts for years to come. 


When repairing broken pipes—blocked toilet drains, broken kitchen pipes, and all other types of damaged pipes—pipe relining is strongly advised. It is more adaptable since it clings to a wide variety of pipe materials.
