Need pipe lining services in Sydney?

Before considering excavating your broken pipe, existing sewer or storm water pipes, give our Sydney pipe lining experts a call!

See how Trenchless pipe relining not only repairs broken pipe lining, but also witness how we deal with emergency pipe relining with minimal to no disturbance to the surrounding environment.

Our Sydney pipe lining experts reline the existing pipe with an epoxy resin-impregnated liner, which forms a new one-piece pipe within the existing pipe. To fix the broken pipe, the new pipe bonds to the old by extruding resin into the original pipe joints. Trenchless pipe repair not only locks the two pipes together, but also prevents tree roots from entering the pipe and growing between the old pipe and the new pipe lining.

Pipe lining is a fast, clean and permanent process. Broken pipe lining repairs can be done in pipe diameters from 50mm to 300mm, and trenchless pipe repair can be anything from 1 metre up to 100 metres.

Case Study #1:

Pipe Relining of Internal Vertical Stacks.

Many people only associate Pipe Relining with the renewal of underground services. This article is to outline another importance of Trenchless pipe lining services where Pipe Relining was utilised to save our clients thousands of dollars and potentially weeks of disruption and inconvenience to residents.

Our client manages a block of 24 units over 6 levels. They had been suffering from continual water leaks originating from the old cast iron and galvanised stack work carrying bathroom grey water, sewer, and kitchen waste from each level to the sewer system underground. The original plumbing within the building had been configured in such a way that each of the 3 wastes where contained within their individual stacks, this was to meet the old plumbing code of practice. This group of 3 stacks was repeated in each of the four corners of the building. Four groups of three stacks obviously creates the potential for a large number of leaks.

Two of these stacks, bathroom grey water (shower, bath, basins) and toilet waste where contained within one cavity, and the kitchen waste was contained in another cavity on the opposite side of the unit.

In meeting with the new code of practice, Trenchless pipe lining experts gave a proposal to our client to reline the 100mm cast iron toilet waste stack from the rooftop to the main line, underground. Reinstate the toilet junctions from the roof top with the use of our robotic junction cutter, and then by accessing the roof cavity within the bathroom of each unit, redivert all the galvanised bathroom waste water pipe work into the new relined 100mm stack. This would eliminate one entire stack from the building, minimizing any potential for future leaks. This would leave the building with a brand new relined pipe, stronger than a new PVC pipe and all this work was carried out by Sydney pipe lining experts with minimal disturbance to residents with only a small access panel being cut in each unit, leaving only small pipe lining restoration costs.

The proposal also included pipe relining of the existing 80mm galvanised iron kitchen waste stack again from the rooftop to the sub floor drainage. The reinstatement of each units kitchen drainage would then involve accessing each unit, removing the kitchen trap and with the use of a flexible hole saw reinstate the kitchen drainage.

In total, our pipe relining proposal would be completed within one week, would eliminate one entire stack, cause minimal disturbance to residents and provide the residents with brand new stack work.

The alternative was to access each bathroom, of which the majority, where fully renovated, demolish the existing stack work to gain access to the pipe work, replace the pipe work and fittings, and reinstate the bathrooms. The time line for a pipe lining project of this size was weeks, with the restoration costs being an unknown, depending on availability of trades and not to mention the availability of tiles, etc.

The pipe lining project was undertaken to renew the first group of stacks, and was completed within time and on budget. The entire pipe repair project was great success, and a program is now in place to continue with the remaining stacks over a period of time.

Case Study #2:

Reline Alamein Fountain - Kings Cross.

Reline Alamein Fountain

Many people only associate Pipe Relining with the renewal of damaged sewer or storm water pipes. This case study is to outline another successful application for pipe relining.

Our client knew they were losing a lot of water from the fountain. The amount of water was too substantial to just be from evaporation or above ground. After carrying out camera inspections of the sub surface water return lines with the use of our Ibak robotic camera, the need to repair broken pipes became obvious as there were several major displacements within the pipes as well as a broken junction that had been used in place of a bend.

Pipe Repair Pipe Lining

The options faced by our client was to either take the fountain out of action for an unknown period of time whilst they excavated the defective areas, replace the pipe work and then rebuild the water feature, re-water proof and then retile the fountain, or to use pipe relining technique that will restore the entire fountain return line drainage through one very small excavation and the available pipe access within the holding tank.


The pipe lining project involved the installation of 3 X one piece epoxy resin impregnated liners within the existing 100 & 150mm drainage return lines, reinstate the water return pipe junctions with the use of our robotic junction cutter and install resin impregnated patch repair liners into the vertical copper / cast iron vertical risers into the fountain that govern the water height.

The project was completed within 4 days with no scaring or evidence of the pipe relining work that had just been carried out.

Since completing the pipe lining project, the water consumption of the fountain has reduced dramatically.

Frequently Asked Questions About Pipe Relining

Question: For pipe relining to be done, what hole size needs to be dug?

Answer: The size of hole will be dug depending on how the present pipe is constructed as well as the style of pipe relining that will be used for the installation. There are situations when only a small hole needs to be dug but there are also cases when excavation can be avoided 100%.

Question: Will the size of the pipe diameter decreased?

Answer: There may be a size difference on the overall diameter of the pipe but only by 6mm. The reduction of pipe diameter is very minimal that it will not affect the pipe’s capacity at all.

Question: Are there methods that will help determine if pipe relining will suit my application or if it can solve my problem?
