We understand that pipe relining can be a bit of an unknown quantity for your average Joe. With that in mind, we’ve detailed some FAQ’s and responses below to help answer any immediate questions you may have.
If you need more information or you’re just curious, you can also check out our education and services pages or give us a call anytime.
Once you reline, will the new material move around inside the old pipe?
A common question in the relining industry is; will my new, relined pipe, slip back and forth within the existing, damaged pipe? Quite simply, no. But for your piece of mind and because we know how much you love to geek-out on relining, here are the two reasons that this is not the case.
Mechanical forces are those forces which involve contact with the other object, on which the force is applied. When a pipe is relined, the epoxy resin that is used is physically forced onto the inside of the existing pipe using an inflation tube or pressurised bladder (yes, the irony doesn’t escape us), forcing the liner in place.
Once the liner has been forced in place, the epoxy resin seeps into the cracks, crevices and joints. It then hardens forming chemical bonds with the existing pipes and anchoring itself within, making it impossible for it to move.
Once in place, the newly relined section of pipe not only becomes functional again but more structurally sound than the original materials, significantly reducing the risk of any further issues.
How do we reline your pipes without digging up your back yard?
The first step in the process is to use our CC.TV equipment (a fancy camera) to assess the pipes and locate the problem.
This is essential as we need to be sure which section of pipe is damaged and therefore, requires relining. Once the problem has been found, we scour the line clean with high-pressure water, to clear and debris.
This process allows us to devise a custom solution based on the amount of relining required and the access we have to the drainage system. Often, a plumber is able to provide a rough indication as to the scale of the job. However, it’s imperative that we go through this initial phase to establish the best solution and ultimately, only charge you for the work you need.
From here, we impregnate a felt tube with strong epoxy resin before deploying it within the existing, damaged pipe. We can deploy the new pipe in one of two ways, depending on the complexity of the job.
- In most cases, we can “invert” a long section of liner into the existing pipe at the same time as impregnating it with the resin. However;
- For smaller customised sections of pipe that require relining, we use a method called ‘tow in place’ which allows us to more easily navigate junctions.
Once in place, we inflate the tube with air, water or steam, which produces a solid structure and a brand new pipe within the existing one.
What is the ‘root’ of the problem?
Over time, pipes move, crack and generally deteriorate. No matter the quality of the installation.
This allows wastewater to escape the system, bringing with it a world of trouble – and so it begins. Tree roots love water, especially water from the sewer containing plenty of nutrients to help them grow (Yuk). They thrive in this environment and often grow at extremely quick rates. As they grow, roots can cause blockages within the pipe and can even break them apart as they expand.
Unfortunately, most of this disruption typically occurs underground, leaving you with no idea what is going on and a whole host of potential issues to deal with.
If left unattended (standard pressure included), the water starts to escape so much that it eventually drags in the surrounding soil. this can cause subsidence and structural damage to surrounding objects such as walls, columns and footpaths and more often than not, completely ruining the pipe. Leaving you with little option but to dig up your backyard to replace it. If only you’d relined sooner, hey!
Identifying this problem early with the use of CC.TV can be invaluable and allows for a relining solution to be deployed in good time, ultimately saving time and disruption down the track.
Why is relining preferred to the traditional dig and replace?
After you’ve called your plumber to unblock your drain for the umpteenth time, you’re going to be a little fed up.
You need a long-term solution and despite their best and no doubt valiant efforts, your plumber is out of ideas. At this point, you’re faced with 2 options;
Dig, and replace your existing pipes
Don’t dig, and reline the existing pipes
With the technology available today, pipe relining is the preferred and superior option. You may be thinking ‘well they’re going to say that’, which is completely understandable. But here is why;
- Time – Pipe relining often takes less than half the time of traditional methods and depending on the location, can be exceedingly more efficient.
- Disruption (or lack of) – Disruptions of day to day living is one thing, but disruptions to the surrounding structural environment can be devastating in the long term. Relining is a completely non-invasive method from start to finish for both the home and those living in it.
- Cash – It only makes sense that a lack of mass excavation requires less labour, over less time. So in turn, relining will typically cost you less, not to mention a longer life expectancy for the newly relined pipe than a replacement.
The efficiency of the process both in terms of time and money. Along with a manufacturer’s product guarantee of up to 50 years, makes relining a no-brainer – duh!
Can you reline bends?
Yes! We have the most up-to-date technologies and systems from around the world to ensure we can negotiate around any problem your pipes may have. This includes multiple bends, junctions and is irrespective of access. We can pretty much reline anything!
Do you provide a guarantee?
Yes! Our confidence in the service and product we deliver is such that we’re happy to provide our customers with a 20 year guarantee on our installation, with our versatile products coming with a life expectancy and guarantee of 50 years. This is dependant on the job in question, but we’re happy to discuss this with you!
How long does it take to install?
The time a job takes relates directly to the length of pipe that we are relining. A small section of pipe and can take a couple of hours whilst relining the whole system of a residential house can take up to a week, it really is impossible to say without knowing the scope of the project. That said, there is absolutely no need to move out or anything of the sort, as there are only water restrictions during work hours and we try and make ourselves as invisible as possible.
Why not just dig up and replace the old pipes?
Two reasons: Time & Money!
Pipe relining has been around for over 40 years (believe it or not) and is a proven method to renew your drains, causing less disruption over less time and ultimately delivering a better more durable product, at half the cost.
Excavations are painstaking processes that require heavy labour, which does not come cheap and takes an age. In addition, they can often cause structural disturbance to the surrounding area, requiring further work to be completed down the track – and guess who’s paying for that?
Our process will not only save you money both now and over the long term, but will more often than not take less time and cause less stress than excavating.
Is it environmentally friendly?
Our non-evasive relining methods provide little to no disruption to the surrounding environment.
Once cured, the resins we use are completely harmless to the surrounding soils and environment.
Is your work noisy?
Noise is generally limited to the first hour of the job whilst using the high pressure water jetter to thoroughly clean the pipes before relining. After this, our technology is working away under the surface to reline the damaged section, which causes very little noise.
