What is Pipe Relining?

Damaged sewer or water lines can be very difficult to replace. It requires extensive excavation and a hefty cost, which is why everyone hates it as part of home repair. Luckily, pipe relining technology has developed something much less intrusive and cheaper, repairing damaged pipes without extensive excavation.

Pipe relining creates a new pipe inside the old one by repairing or opening blocked and damaged pipes. A resin-coated liner is inserted into the damaged pipe. A very hard new layer is formed as it hardens, thus saving the entire pipeline from digging trenches or replacing. Pipe relining is a "no-dig" solution, saving much time and money, and your setting.

Let us have an in-depth understanding of how it works and why it would have been the best solution to your damaged pipes.

Common Situations Requiring Pipe Relining

Most people attend to pipe problems only in their worst times, for instance, severe blockages or leakage. Relining can, however, be preventive. The worst case of root intrusion and crumbling can be experienced with a home that has been using clay pipes for decades. The relining will then inhibit any future problems with it.

How Does Pipe Relining Work?

Pipe relining is a technique whereby damaged pipes are corrected from the interior of the pipes through advanced technology. It requires special tools and skills. Here are the main steps involved:

• Step 1: Assess the Damage
  The plumber checks the pipe first to see if it can be relined. A high-resolution camera or even FELL devices will check the pipe's condition. This process helps detect cracks, blockages, or other problems that relining can solve.



• Step 2: Clean the Pipe
  Cleaning ensures the resin sticks well to the pipe's walls. Plumbers employ robotic cutters to eliminate debris and roots. High-pressure water jets eliminate all remaining dirt, grease, and scale buildup. A second camera inspection verifies the pipe is clean and ready for lining.



• Step 3: Installation of Liner
  The plumber inserts a flexible felt or fibreglass liner coated with epoxy resin into the pipe. A bladder inside the liner inflates, pressing the resin-coated material against the pipe walls. This step creates a seamless layer that covers any cracks or minor holes.



• Step 4: Cure the Resin
  The curing process allows the resin to harden. In this stage, the liner is solidified using hot water or UV light. The liner, after being cured, forms a new pipe inside the old one. Robotic cutters are used to remove any excess liner around the junctions of pipes and inspection pits.



• Step 5: Final Inspection
  The plumber does a final check to ensure that the liner is in place and working properly. Cameras confirm the integrity of the relined pipe. The pipe is now ready for use.

Advantages Of Relining Pipes

It has various merits when compared to conventional pipelining such as replacement piping. This is what makes it most preferred:

• Cost-Effective Solution
  Pipe relining saves money by reducing the extensive excavating process. Only a small entry hole is needed to access the pipes, reducing labour and equipment costs and landscaping repairs costs.



• Minimal Disruption
  After all the heavy digging and drilling, you will not have to take your yard, driveway, or garden into custody once you undergo pipe relining. Pipe relining is fast, noiseless, and messless, and causes the least disturbance possible in your property.



• Long-Lasting Results
  The relined pipe is very durable and resistant to roots, cracks, and leaks. Most relined pipes are guaranteed to last between 10 and 50 years.



• Environment Friendly
  Relining eliminates waste as the existing pipe remains intact. There is no old pipe removal and disposal, making it green.



• Versatility
  Pipe relining goes well with all types of pipe-from clay and cast iron to PVC and concrete. Its application is suitable for sewer lines, stormwater drains, and other plumbing systems.

Is Pipe Relining Not Viable in All Situations?

Even though relining is very effective, it is not for every situation. When a pipe is fully crushed or dislodged, relining cannot help recover its functionality. Backfall or high water pooling in the pipes may also not benefit from relining since the new lining will reproduce the problem. In such instances, excavation and replacement might be inevitable.

Preventive Measures and Maintenance

• To prolong the longevity of your pipes, consider taking these preventive measures:


• Plan routine plumbing inspections to identify issues before they become more serious.


• Grease, wipes, and sanitary products should not be flushed down the drain.


• Maintain tree growth near underground pipes and trim roots when appropriate.


• Use professional cleaning services to ensure that your pipes remain free of buildup and blockages.

Final Words

Pipe relining is one of the most advanced solutions in plumbing. It reduces repair costs and simplifies them. It is tough, efficient, and less invasive. It saves you time, money and stress whether it is for emergencies or preventive maintenance. Search for an expert plumber who will evaluate your issue and then tell you what to do. To access even the tiniest and most damages in the pipes, without the need of digging the entire pipe again or replacing the pipes, pipe relining will do.
