Pipe relining: what is it exactly?

Problematic drains can result in many types of issues, causing a lot of frustration to you and others on your premises. Pipe relining technology offers a cheaper, more effective method in fixing damaged piping.

Traditionally, the way in which broken pipes have been fixed involves digging, and dismantling of property structures to reach what’s affected. Coming at a cost both of time and money, this outdated method isn’t at all efficient in the eyes of the customer or plumber.

Relining does as the name suggests; relines the inside of pipes, restoring from a damaged state to its original function. A special solution is inserted within the pipe itself, then left to set and mould to its shape, producing a brand new, fully-operable channel without the arduous digging process.

Who can perform trenchless pipe relining?

The revolutionary method has been present in the industry for over a decade, though isn’t commonly offered by plumbing & drainage specialists. This form of pipe maintenance should only be performed by fully trained & licenced plumbers, with specialist skills in pipe relining.

Pipe relining is a niche specialisation, which a lot of plumbers won’t offer - a pipe relining specialist ought to be entrusted with any and all work you plan on completing on the piping system on your premises.

The pros and cons of pipe relining

Pipe relining has many advantages and some disadvantages, which are outlined as follows:


- an inexpensive option, especially in comparison to traditional methods

- no digging, or dismantling of structures on your premises

- not consuming of time

- in most cases, a new pipe will be able to be installed & in working order within a day


The only notable disadvantage of pipe relining technology is that it can’t always be performed. This occurs when pipes are damaged significantly with large internal gaps, meaning that a pipe reline solution wouldn’t be able to mould into an adequate structure.

In instances where original pipes have minimal damage, the smaller gaps are able to be covered up via a process called pipe patching.

What does the pipe relining process involve?

The pipe relining process is short, yet must be performed by a licenced, fully-trained professional in order to work properly.

Outlined is a step-by-step process on how relining is usually performed in piping systems:


First, a drain camera is placed within the pipe, to inspect for the root cause of the drainage problems.

Drain clearing

Upon discovery of the cause, it will be remedied; most often pipe-clearing technology ridding of a blockage. A secondary inspection follows this in order to ensure no remaining residue in the pipe (this can compromise the relining process).

Reline preparation

The relining case is filled with special resin, then evenly distributed throughout.


A specialised inversion drum is then used to both blow the liner into the pipe, and invert the material to enable the mould.

Pipe curing

The pipe relining specialists will wait for the solution to cure into a protective coating along the pipe.

Cut out junctions and inspection pits

Following the curing, all connected pipes and junctions can be removed from the resin.

Final inspection

A final check is carried out to ensure the problem has been fixed through the relining.
