What Is Pipe Relining and How Does It Work?

When homeowners or property managers hear the words “damaged pipes,” they often picture excavation, noise, and costly landscaping repairs. Traditionally, repairing underground plumbing meant digging up lawns, driveways, or even parts of the home. But thanks to modern plumbing innovations, there’s a far more efficient solution. Pipe relining is a trenchless method that repairs damaged or deteriorating pipes without the need for excavation. It’s fast, reliable, and incredibly effective. It has become the go-to method for permanent pipe repairs across Australia.

Pipe relining works by essentially creating a new, durable pipe inside your existing one. Instead of digging up the old pipe and replacing it, a specially designed liner is inserted into the affected pipe and bonded to the inner walls using a strong epoxy resin. Once cured, this forms a smooth, watertight, and long-lasting inner pipe that restores the original flow and function without disrupting your property. Whether you’re dealing with cracked pipes, tree root intrusion, or repeated blockages, pipe relining provides a long-term fix with minimal mess and downtime.

Here’s how the process works, step-by-step:

CCTV Pipe Inspection

We begin by inserting a drain camera into your pipe system to identify exactly what’s going on. This allows us to locate the problem area, assess the extent of the damage, and determine whether pipe relining is the most suitable solution.

Pipe Cleaning and Preparation

Next, we thoroughly clean the interior of the pipe using high-pressure water jetting. This removes any debris, tree roots, grease, or scale that could interfere with the lining process. In some cases, mechanical cutters may be used to remove more stubborn obstructions.

Inserting the Liner

Once the pipe is clean, a flexible liner soaked in epoxy resin is inserted into the existing pipe. This liner is carefully positioned over the damaged section. An inflatable bladder is used to press the liner firmly against the inner walls of the pipe.

The liner is then left to cure. This can be done using ambient air temperature or accelerated using hot water or steam. As the resin hardens, it forms a new pipe within the old one.

Final Inspection

Once the curing is complete, we remove the bladder and conduct a final camera inspection. This ensures the pipe has been relined correctly and is ready for long-term use.

Why Pipe Relining?

Pipe relining is a powerful solution for a variety of plumbing issues. It’s especially useful in older properties where pipes have cracked or corroded over time, or in areas where tree roots have found their way into the system. Instead of removing and replacing entire sections of pipe, relining allows us to restore functionality without disturbing your home or garden.

One of the biggest advantages of pipe relining is its longevity. A professionally relined pipe can last over 50 years, thanks to the strength and durability of the materials used. The epoxy resin used in the process is resistant to corrosion, blockages, and future root intrusion, making it stronger in many cases than new PVC piping. It’s also approved for both sewer and stormwater applications, making it incredibly versatile.

A non-invasive way to fix the problem!

This method is ideal for residential, commercial, and strata properties alike, particularly where access to the damaged pipe is limited. For homes with pipes running beneath driveways, retaining walls, or concrete slabs, relining offers a non-invasive way to fix the problem without demolishing the surrounding structures. It’s also a faster option, with most jobs completed within a day or two, minimising disruption for tenants and property owners.
