Frequently asked questions about relining in Sydney

What size hole needs to be dug in oder to start the relining process?

Excavation can typically be totally avoided depending on the existing pipe configuration and repair style. If necessary, only one small excavation will be required, which is much less than full pipe replacement.

Is there going to be a decrease in the pipe diameter?

The relined pipes overall diameter decreases by 6mm, but this does not impact its required capacity. In fact, the smoother inner epoxy resin surface of the pipe improves flow rate and self-cleansing properties.

What are the measurements for the pipe’s diameter and length?

We have the capability to process lines ranging from 50mm to 250mm in diameter, with a maximum length of up to 50 meters or more.

Do you only line sewer lines?

It is possible to line any pipe and not just a sewer pipe, whether it is horizontal or vertical, round or rectangular, for sanitary sewer, stormwater drains, or any other waste or water pipe or drainage system. Our relining pipe services can rehabilitate them all.

It is possible to reline multiple bends with just one liner. Our team have the skill and equipment to do these types of pipe relining services. All we need is a CCTV camera to plan out where the bends are and we can make the repairs work.

Can you reline junctions?

Yes, we have the capability to install a full one-piece junction liner and restore junctions.

What will occur if tree roots have gone into the pipe?

The pipe undergoes cleaning using high-pressure water jet, typically resulting in tree root intrusion removal that allows for problem assessment as the blocked drain would have been now cleared. After cleaning, the pipe can be relined to prevent root re-entry. The pipe will be inspected using CCTV inspections to ensure it is clear and ready for the epoxy resin liner.

What is the size of the pipe that can be relined?

Pipes ranging from 40mm to 225mm in diameter are eligible for relining. CCTV drain inspections will determine the size of the pipes and the suitability for relining trenchless technology.

Is relining expensive?

When considering all aspects, relining the pipe is a cost-effective and eco-friendly option in comparison to digging up and replacing it.

Is relining guaranteed?

We offer a 50 year guarantee on every job we complete, which is typically double the guarantee provided by most plumbers who opt to dig up and replace instead.

Will roots be able to re-enter my pipe after it has been relined?

No, the liner creates a new pipe within the old pipe so strong that the tree roots cannot enter.

Can you fix a broken junction piece?

The one-piece junction seal can be installed in 100 or 150mm junctions with different configurations for both 45 and 90 degree applications.

What is the reason many plumbers don’t recommend this type of repair?

Put simply, not all plumbers are trained in relining and may not have the capacity to do relining or install a cured-in-place pipe. Many plumbers also resist change and hesitate to provide services they are unfamiliar with. Relining can be viewed as a threat by some plumbers, as it eliminates the need for regular water jetter drain cleaning.

I need to figure out if relining is appropriate for my application and if it will solve my issue.

A drain camera inspection is necessary to decide on the most suitable repair method for each situation and drain plumbing problems. While relining may not work in all cases, it could still be required in addition to traditional repair techniques to repair pipe work.
