Opt For This Cost-Effective Solution

An underground sewer system leak caused by a broken pipe is a major problem and it can happen for a number of reasons. Shifting soil can eventually cause a crack in the pipe, resulting in a blockage. Another common cause of blocked drains and burst pipes in New South Wales and Canberra is tree roots encroaching on the pipes.

In severe situations, a plumbing professional might be needed to excavate the area and reconstruct the broken pipe. For those pipes that only have localised damage to a specific part of a pipe, modern technology offers us the option of drain relining or drain patching.

Pipe Relining Or Repatching

What Is Drain Pipe Relining?

Relining a drain is the process of putting a new pipe in where an old pipe has a leak or has been damaged.

How are Drain Pipes Relined?

By using air pressure, epoxy and resin material are cured in place to patch up the damaged pipe. Using this trenchless technology you can repair your plumbing system for the fraction of the cost. Pipe Relining brings you a no-dig technology that will save your garden and paved yards from excavation whilst repairing your damaged or old pipes.

Benefits of Drain Relining

Non-evasive pipe repair

When the blocked drain or broken pipe lies underneath your garage, concrete driveways, slabs, or garden, traditional pipe replacement requires a large excavation site to dig out the defective pipe using an excavator. However, drain relining does not require a whole site excavation.

Low-cost Solution

Digging a yard to fix a defective pipe usually entails bigger costs. Aside from the actual drain repair, you also have to allocate a sum of money for the repair and restoration of your garden and pipe. These additional costs do not apply to drain relining.


A reinforced pipe through drain relining lasts up to an estimated 20 years. Since the epoxy resin pipe is inserted into the old pipe, it is having two pipes in place.

Quick Turnaround

Drain relining is simple and effective. The job is quicker than the traditional way of pipe replacement. The curing of the pipe lining only takes not less than an hour and the whole job can take an average of less than a day. 

The Relining Process

As a homeowner and property manager, it is important to understand and educate yourself on how the relining process works. Drain relining is a quick, no-hassle pipe and drains replacement process that will not cause any disturbance to your neighbors. Digging is only confined to the access points and there is no need to excavate the whole area. Here is a simple guide for you.

Step 1: Inspection

Our experienced plumbers will insert small cameras down the drain to inspect the extent and severity of the damage. They will also assess if pipe relining or repatching is applicable to your case.

Step 2: Blocked Drain Clearing

Blocked sewers are usually an after effect of cracked or broken pipes. Blocked drains should be cleared first. After clearing the drain, the site will be inspected again to know how much material is needed for the pipe repatching.

Step 3: Mixture Preparation

The liner will be mixed and flattened out on site. With the aid of a CCTV camera, the liner will be carefully laid down to the target pipe or damaged area that requires lining.

Step 4 : Curing The Lining
