Pipe Relining Vs Pipe Replacement

Pipe Relining Vs Pipe Replacement

Which Is The Best Method To Repair Your Pipe?

Has your home recently developed seriously blocked drains in your sewer pipes from tree roots or a burst pipe? A plumber might suggest pipe relining or pipe replacement to solve your plumbing problem.

If you’re unsure about the difference between pipe relining and pipe replacement, or which one is the better solution to fix your plumbing problem, this guide is for you.

With over 15 years of experience as pipe repair specialists, we’re breaking down pipe relining vs pipe replacement for you.

What Is Pipe Relining?

Pipe relining is a technique that specialist plumbers use to fix structural damage in the interior of pipes. While pipe relining technology has been available in Australia for more than a decade now, it’s still a relatively unknown alternative to pipe replacement.

Drainage excavation requires a team of plumbers to dig up your yard to locate the damaged pipe and replace it. Pipe relining, however, is a no-dig method for pipe repair. Only a small entry hole is required to access your pipes by a pipe relining specialist.

An epoxy resin-covered tube is inserted into the damaged pipe and inflated. When the inflated tube is flush with the pipe walls, the resin adheres to it. This forms a hard protective coat inside the damaged area of the pipe and seals it. Your sewer pipes are just about brand new!

Before inserting the inflatable tube for pipe relining, the pipe must be cleaned out. Your plumber might use an electric drain cleaner or a hydro jet for this step. CCTV drain cameras are used to inspect the pipes to ensure they are ready for pipe relining. With the tube inside and inflated, the resin must be left to cure. When the resin is cured, it has hardened and formed a seal on the inside of the pipe.

What Issues Can Pipe Relining Fix?

Pipe relining can fix many issues that result from structural damage — everything from cracks, sag and misaligned pipes to damage from wayward tree roots. Not only does it fix most of these issues, but it can also actively prevent them from occurring in the future.

A major win for relining in the pipe relining vs replacement debate is that pipe relining is a more cost-effective method to repair broken pipes from the inside out.

What Is Pipe Replacement?

Pipe replacement used to be the only method to repair a broken or damaged sewer line. The pipe replacement method is the traditional method of digging up the old pipe and replacing it with a new one. With pipe relining becoming available, excavation isn’t always required now thankfully.

When the site of the blockage or damaged pipe has been excavated, it can be removed and replaced with a new pipe. The pipe can be repaired, however, it won’t be long before the problem will reoccur and it will need to be dug up again. This is why we recommend replacing damaged pipes with a new one, rather than pipe repair.

Drainage excavation requires a whole team of plumbers and can take a few days to complete. Moreover, your garden is dug up and the landscaping ruined in the process. On top of paying for a costly excavation and pipe replacement, you’ll also be up for landscaping costs to get your garden back in shape. These reasons are why we often find pipe relining wins out in the pipe relining vs replacement debate.

What Issues Can Pipe Replacement Fix?

While pipe relining is better than replacement in most circumstances, if the damage to your pipes is significant, pipe relining may not be sufficient. It’s important to have a professional assess the damage to determine whether pipe relining is possible. If not, you’ll need to completely replace your old pipe with a pipe replacement.

Advantages Of Pipe Relining

Traditional pipe replacement can be labour-intensive and involve reinstatement of surface finishes. This translates into a higher financial cost.

Pipe relining is a much more cost-effective alternative as there’s no need to dig up anything, and the finished relined pipe achieves exactly the same result as a set of brand new pipes.

Seeking a pipe relining specialist to assess and fix your pipes could save you thousands of dollars, compared to a traditional pipe replacement from a non-specialist plumber.

In many ways, pipe relining is more effective in fixing broken and damaged pipes than pipe replacement. With pipe replacement, you’re paying for the plumber to dig trenches and dismantle walls, concrete slabs and your yard in order to completely replace your broken or damaged pipes.

In contrast, pipe relining requires a single access hole that measures only a square metre. The relining is far less expensive than purchasing new pipes and it’s super convenient with no need to dispose of your old pipes.

Advantages of trenchless pipe relining includes the following:

  • Pipe relining is less intrusive for residents than traditional pipe repairs
  • Pipe relining seals the pipe entirely, leaving no chance for leaks, or tree roots to intrude the pipe space
  • Pipe relining has a very fast turnaround time
  • Trenchless pipe relining is far more cost-effective than the pipe replacement method
  • Pipe relining material is extremely strong, durable and long-lasting
  • The smooth surface of a relined pipe increases the flow capacity and keeps the pipes clean

Disadvantages Of Pipe Relining

Unfortunately, pipe relining is not possible in the following cases:

  • Your pipes have experienced severe tree root damage, including becoming crushed
  • Your pipes are displaced significantly
  • Your pipes have sags or backfall and are holding water

Pipe relining may not work in these situations as the relining material will have no interior surface to cling to. In saying that, there are many innovative methods to install a liner which might be an option for you.

How Much Does Pipe Relining Cost?

Pipe relining costs will vary depending on each situation. The cost of pipe relining in Sydney per metre can be anywhere from $400 to $1100 or more.

Pipe relining can seem expensive in the short term when compared to traditional replacement, but it comes out on top when considering the added costs of installing a new driveway, the hassle of excavation and all the amount of time it takes.

It’s important to note each job can vary significantly depending on the site or equipment required, we highly recommend you consult one of our professionals to get an accurate free quote.

If it seems like too much of a fuss to get your pipes relined, ask yourself how much more inconvenient it might be when a pipe starts to leak and the plumbers tell you they need to dig up your driveway, landscape, or even your premises.

Who Can Perform Pipe Relining?

Since pipe relining is a niche specialisation, not all plumbers will offer pipe relining services. It is also recommended to use pipe relining specialists rather than your local plumber for these types of solutions.
