Why Pipe Relining Is a Modern Solution for Old Pipes

20 December, 2024

Across Sydney, there are places where ageing plumbing carries the city's water to heritage homes in the same pipes that were first laid down from several decades to a century ago. While heritage plumbing systems are made from hardy materials like clay and cast iron, once they reach their century of service, they can begin to rapidly deteriorate. With more appliances and more taps needing more water in renovated homes, the original plumbing system faces ever more pressure, which can mean that wear and tear and other damage also accelerates.

The challenge of dealing with old, deteriorating pipes is to determine whether the damage is severe enough to warrant traditional repair methods vs. effective modern solutions like pipe relining. Where possible, we always strive to leave the original plumbing in place, reinforcing the damaged pipe with epoxy resin relining technology. This practical, modern solution is efficient, contributes to pipe longevity (with repairs having a lifespan of 50 years), and is entirely trenchless, which means repairs are performed without any digging or damage to the garden or landscaping whatsoever.

What is Pipe Relining?

Pipe relining is an innovative technology that helps with the restoration of existing pipe infrastructure by reinforcing the pipe from the inside, rather than replacing it entirely. An epoxy resin fibreglass-threaded sleeve is fitted inside the pipe to cover the damaged section before it is inflated and sealed off, creating a seamless repair to cover every crack and leak.

This revolutionary method is completely non-invasive and costs roughly 20–30% of the price of completely replacing the same length of pipe. Additionally, it allows heritage homes to keep their original pipes and plumbing, even if they experience damage, ensuring that the home does not lose any of its historical character. This preservation aspect makes pipe relining perfectly suitable for repairing and supporting old pipes.

Pipe Relining vs Traditional Pipe Replacement

Pipe relining is a more efficient, cost-effective, and sustainable method of pipe repair than traditional pipe replacement methods. With traditional methods, the pipe's location has to be dug up, damaging concrete or the driveway, or tearing up other parts of the local environment like the landscaping or gardening. The pipe is then removed and replaced, with the old pipe being thrown into landfill.

With pipe relining, there is no need for excavation nor is there any major disruption to the site. In fact, pipe relining is usually conducted from the nearest drain entrance to maintain the integrity of the sight while providing unmatched durability beneath the surface.

What are the Key Benefits of Pipe Relining?

The many benefits of pipe relining your next plumbing issue include:

  • Non-invasive, no excavation, and minimal disruption to the property.
  • Environmentally friendly with no need for digging or contributing to landfill.
  • Cost-effective compared to full pipe replacement, costing about a quarter of the price of a replacement.
  • Durable and long-lasting solution for various pipe issues, lasting for up to 50 years.
  • Keep old pipes to maintain the character and heritage of older properties.
  • Quicker than a full pipe replacement and can often be done on the same day as your plumber visits.

What's Involved in the Pipe Relining Process?

First, a CCTV camera is inserted into the pipe to identify the length and breadth of the damage, as well as determine the cause. In the case of a simple burst pipe, the area will then be cleaned of dirt and debris. Blockages will be removed or broken down and flushed out. For something like a tree root intrusion, high pressure water will be applied to cut the root blockage and prepare the ruptured section.

After the area is cleared and cleaned, a sleeve lining made of epoxy resin is fed into the damaged section and then inflated. As the lining presses up against the damaged section, it is then cured and hardened using UV light, creating a firm and unyielding barrier against the damage, keeping water in and debris out. The repair is then tested to face the required water pressure to check that all leaks have been perfectly sealed up, and documentation is provided certifying the fix.

The whole process, from preparation to post-installation inspection, should take no more than a few hours and can typically be completed on the same day as your plumber's visit. In fact, many jobs can even be completed by the team at Plumberoo by the early afternoon. Plumbing problems that once took days to fix can now be repaired more strongly than they were before in just a matter of hours.

When Is Pipe Relining Suitable?

Pipe relining is ideal for both residential properties and commercial buildings and excels in repairing pipes in hard-to-access areas. One of the factors that make relining so versatile is that it can be conducted above ground with camera technology, the relining sleeve, and any other equipment being fed down from drains or surface level pipes.

Common plumbing issues that are suitable for pipe relining include cracks, corrosion, and root intrusion, where a crack or puncture has been made to the pipe's integrity and needs to be sealed again. Even substantial damage can be smoothed over with our advanced epoxy resin sleeve technology, which hardens to be able to withstand all the pressure and wear and tear that the water supply can throw at it.

In fact, the only type of pipe damage that pipe relining isn't suitable for is when the pipe has been completely destroyed or broken into parts. Of course, this is an exceptionally rare occurrence and more often than not, even severe damage can be reliably fixed with relining.

The Cost Comparison and ROI of Pipe Relining

The cost of pipe relining is a fraction of that of a full pipe replacement, costing only 20–30% of what a complete replacement would be. Relining materials also require minimal maintenance over time as the epoxy resin sleeve is designed to be resistant to corrosion, abrasion, and tree root intrusions. Sealing over initial cracks and damage also reinforces the affected section of pipe, preventing damage from spreading further.

With a repair lifetime of up to 50 years, pipe relining can also add value to older properties, as prospective buyers can see that little to no maintenance will be required over the coming decades. This can add a great deal of value to the already valuable heritage-style properties that are already so popular around Sydney.
