We get it – not everyone is going to be as passionate about relining as we are. However we also know though, that many of you may want more info. Below there is a collection of content, designed to educate you on the ins and outs of relining and outline our industry and technology in more detail. If that’s not enough though, get in touch, we could talk about relining all day!

The first step in the process is to use our CC.TV equipment (a fancy camera) to assess the pipes and locate the problem, this is essential as we need to be sure which section of pipe is damaged and therefore, requires relining. This is then followed closely by scouring the line clean with high pressure water, to clear and debris.


This allows us to devise a custom solution based on the amount of relining required and the type of access we have have to the drainage. Often, a plumber is able to provide a rough indication as to the scale of the job, however it’s imperative that we go through this initial phase to establish the best solution and ultimately, only charge for the work required.


From here, we impregnate a felt tube with strong epoxy resin before deploying it within the existing, damaged pipe. We can deploy the new pipe in one of two ways, depending on the complexity of the job.


  • In most cases, we can “invert” a long section of liner into the existing pipe at the same time as impregnating it with the resin. However;
  • For smaller customised sections of pipe that require relining, we use a method called ‘tow in place’ which allows us to more easily navigate junctions.


Once in place, we inflate the tube with air, water or steam, which produces a solid structure and a brand new pipe within the existing one.


Simple, really.

Over time, pipes move, crack and generally deteriorate, no matter the quality of the installation. This allows wastewater to escape the system, bringing with it a world of trouble – and so it begins.


Tree roots love water, especially water from the sewer containing plenty of nutrients to help them grow (Yuk). They thrive in this environment and often grow at extremely quick rates. As they grow, roots often cause blockages within the pipe and can even break them apart further as they expand.


Unfortunately, most of this disruption typically occurs underground, leaving you with no idea what is going on and a whole host of potential issues to deal with.


If left unattended (standard pressure included), the water starts to escape so much that it eventually drags in surrounding soil causing subsidence and structural damage to surrounding objects such as walls, columns and footpaths, whilst completely ruining the pipe and leaving you with little option but to dig up your backyard to replace it.


Identifying this problem early with the use of CC.TV can be invaluable and allows for a relining solution to be deployed in good time, ultimately saving time and disruption down the track.

After you’ve called your plumber to unblock your drain for the umpteenth time, you’re going to be a little fed up. You need a long term solution and despite their best and no doubt valiant efforts, your plumber is out of ideas. At this point, you’re faced with 2 options;

  • Dig, and replace your existing pipes
  • Don’t dig, and reline the existing pipes

With the technology available today, pipe relining is the preferred and ultimately superior option. You may be thinking ‘well they’re going to say that’, which is completely understandable, but here is why;


  • Time – Pipe relining often takes less than half the time of traditional methods and depending on the location, can be exceedingly more efficient.
  • Disruption (or lack of) – Disruptions of day to day living is one thing, but disruptions to the surrounding structural environment can be devastating long term. Relining is a completely non-invasive method from start to finish for both the home and those living in it.
  • Cash – It only makes sense that a lack of mass excavation requires less labour, over less time, in turn costing you less cash, not to mention a longer life expectancy for the newly relined pipe than a replacement.


The efficiency of the process, both in terms of time and money along with a manufacturer’s product guarantee of up to 50 years makes relining a no-brainer – duh!

Pipe relining is still somewhat of an unknown quantity for many, and whilst at Sydney Relining we’re committed to increasing the profile and education of our profession, some of the subtleties and finer details can be difficult to grasp, especially if you’ve never heard of relining before you need it.


This can often present problems when comparing quotes and proposals from various suppliers. How do you know if you’re comparing apples with apples, or a Valiant Charger with a Porsche?


There are a number of factors to consider, depending on the job and provider. We’ve listed the big ones below, so you’re informed when you bite the bullet and commit to a long term relining solution:


  • What reline material / product is being used? We use only the highest quality epoxy resin, make sure your quote includes the same!


  • Is relining the core business of the provider, or just an add on? The latter will often incur significant overheads, compared to a professional relining outfit.


  • Does your quote offer a guarantee? All quality relining products are insured by the manufacturer, so if this isn’t included, it should be! We offer a 20 year guarantee with all our installations.


  • Is the quote more or less than a traditional ‘dig and replace’ solution? Relining is designed to be a cheaper, more sustainable solution, so bare this in mind.
