drain pipe relining

Trying to fix damaged drain pipes is a major challenging, especially if they are located underground. 

The traditional method for drain pipe repair usually involves having to dig up the pipes and then repairing the damage such as cracks, corrosion, or tree root ingress. 

However, this in itself poses other challenges, such as landscape disruption, increased labour and expenses not to mention how much time it takes.

Because of this, there are new ways where you can easily repair your drain pipes without having to encounter these challenges. One of these ways is with trenchless drain relining.

In this article, we’ll tell you everything about trenchless pipe repair—what it is, how it works, and why it is beneficial.

What Is Trenchless Drain Pipe Relining?

Trenchless drain pipe relining is a more efficient substitute for traditional methods of pipe repairs for the main reason that it does not require any digging.

Instead, it makes use of a unique and innovative type of technology so that you don’t need to disrupt and damage your landscape by digging up trenches, hence the name “trenchless pipe repair.”

Though there is very minimal digging work, your backyard or garden won’t suffer as much structural damage in comparison to traditional pipe repair methods. 

How Does It Actually Work?

Here is the step-by-step process for how trenchless pipe repairs are carried out:

1). Inspection. Before anything, the pipeline to be repaired will be examined and inspected by a CCTV drainage camera, a high-tech device that is used to survey pipe interiors. These are useful in helping gauge the condition of the pipes and identifying any existing or potential problems.

2). Cleaning. Once the problem point of the pipe has been identified, the pipe will be accessed from its shallowest point and will then be deep cleaned with a high-pressure water jet. This is to both clean and clear out any debris within the pipes.

3). Drain Pipe Lining. After the drain pipe has been thoroughly cleaned and washed, a new epoxy pipe liner will be inserted into the drain pipe. This pipe liner is useful because it will be installed in the damaged pipe without the need to replace it. This also helps increase the structural integrity of the pipe.

As mentioned before, there is minimal digging involved in trenchless drain pipe repair, and this is the stage in which it happens. A small access hole will be dug in order to install the drain pipe liner. 

After the pipe liner is installed, it will be inflated with air and will be left for a while so that it can cure in place and merge together with the old pipe.

Once this happens, the process is finished! You have a repaired pipe that is good as new.

What Are Some Benefits of Trenchless Drain Pipe Repair?

The process of trenchless drain pipe repair is highly efficient. As such, the benefits are undeniable. Here are just some of them:

1). Cost-Effective. This is perhaps the main benefit of trenchless pipe repairs. Trenchless pipe repairs are both cost-effective and convenient because it eliminates the expense of disrupting your garden or yard and then restoring it again.

Moreover, you don’t need to spend extra money on purchasing new drainpipes and installing them. All you need to worry about is the pipe liner itself and the labour! 

Therefore, not only is this an environmentally friendly option, but you will also avoid having to spend money on landscape restoration and on additional pipe products. 

2). Quick and Easy. Of course, this is another benefit of trenchless pipe relining. The whole process is pretty quick and saves you a lot of time since you don’t have to dig up the whole pipe and repair it from there. 

3). Sustainable. Trenchless pipe reparation is a lot more sustainable in comparison to traditional pipe repairs. This is because the technology used in this process is high quality and increases the durability and strength of your once damaged pipes.

Moreover, these results will last for the long-term future as well! You won’t need to worry about damaged pipes for a long, long time. 


As you can see, the benefits of trenchless drain pipe relining are endless. By using technology that makes pipe repairing a lot more efficient, trenchless pipe repairs are undeniably the best option to choose for your damaged drain pipes. So, what are you waiting for? Try this out now!

Advantages Drain Relining

Are your drains at home broken or leaking? Do you wonder whether you should reline your pipes or replace them completely?

Well, wonder no more, because we’ve got you covered! We’re here to tell you why you should seriously consider drain relining.

What Is Drain Lining?

Before we discuss the advantages of drain pipe relining, we want to make sure that you understand what it actually is. 

Drain relining is an innovative method to repair worn-out pipes that are tricky to access and have structural defects such as cracks, misalignments, and sags. 

This is considered to be more advantageous than the traditional method of pipe replacement because it eliminates a considerable amount of different inconveniences such as infrastructure replacement and landscape restoration. 

When Can I Pursue Pipe Relining?

Drain relining has several advantages but can only be used in certain situations. For example, if your pipes:

  • Are suffering from severe damage like being crushed from tree roots
  • Are displaced or misaligned
  • Has sags and backfalls that contain water

With these examples, pipe relining may not be able to fix these problems. However, drain pipe relining has been specially designed to fix many other situations where worn-out pipes are suffering from structural defects. 

Advantages of Pipe Relining

There are plenty of advantages with pipe relining that is especially beneficial in terms of the long-term future. Listed below are some pertinent examples: 

1). Minimal Landscape Disruption

This is one of the main advantages of drain relining because if you replace pipes entirely, you need to carry out excavation which can destroy your garden and create more inconveniences.

There is nothing worse than having to dig up the ground and restore it back to its original state, removing plant covers and having to replace them, and destroying concrete and pavements which are hard to restore.

By opting to reline your pipe, you can save yourself all of those troubles.

Drain pipe relining serves as the much more convenient alternative as you don’t have to rehabilitate the work area and you can be more environmentally-friendly in the process. 

2). Cost-Effective 

Because pipe relining does not require large scale excavation like pipe replacements, you can save much more money because of the reduced job duration (lesser labour costs) and equipment expenses.

Moreover, the most important expense you will be eliminating is the infrastructure replacement expense because you will not be destroying gardens, concrete pavements, and other types of infrastructure.

3). Faster To Accomplish

Pipe relining does not take a long time to complete and install. They can take a few days at most depending on the size of the project or job in question.

There are also different types of express offers and options for emergency cases to help speed up the pipe relining process.

4). Enhanced Durability

Relining your drain pipes helps enhance their durability and helps strengthen their structural integrity.

This means that they become resistant to forces from things like tree roots and ensures that this durability is even throughout the whole pipe by strengthening weak links and spots.

5). Increased Longevity

With enhanced durability comes increased longevity. Relined pipes can last for more than 20 years, which definitely makes your purchase a worthy investment.

6). Effective Preventive Measure

Relining your drain pipes also prepares for the possibility of future structural damage threats.

For example, relined pipes are specially sealed to prevent moisture from leaking out of the pipe and from water entering the pipe. 

Relined pipes have already been made more durable and stronger so they can resist normal threats like tree roots, which is an important anticipation factor to consider for your pipes. 


Though relining drain pipes is not exactly ideal for severely damaged pipes, this method of pipe reparation is not a bandaid solution. 

Unlike pipe replacement, pipe relining will not require extra labour, infrastructure replacement, and restoration expenses. It is also faster to complete, which means you can save both time and money.

Moreover, with pipe relining you can help increase the longevity and durability of your pipes. As a bonus, you are also helping out the environment by not displacing plants and trees and ruining soil integrity and conditions. 

Therefore, it is important to understand that this method is an investment that you will definitely get the best from in the future years to come.

Digging Drain Relining

While standing water and things like bad smells and slow draining sinks are clear signs of a blockage, the signs of damage to the interior of your drains are not always visible and if not spotted early may lead to severe and more expensive problems further down the line.

When you have signs of damage to your pipes such as a leak, a burst pipe or a total collapse, you need to turn to professionals for help.

There are several ways to fix broken drains; however, perhaps the most effective way to take care of your drain issues permanently is with drain relining.

Drain Relining

Drain relining is a technique used to solve severe drain and pipe issues by fitting a protective layer to the interior of the drains, creating a reinforced coating that prevents further damage and protects your drain against cracks.

Drain relining is not only practical but also an affordable way to fix your drain and sewer, and more importantly, there’s no digging required.

After all, drain relining is also referred to as trenchless drain repair technology.

Drain relining has many benefits, which makes it the perfect solution to all your drain issues, especially if you don’t like the idea of technicians digging trenches in your commercial or residential property.

Here’s a closer look at the drain relining process:

  • Initial Inspection
  • Drain Cleaning
  • No-Dig Drain Lining Installation
  • Excavation (The Last Resort)

Initial Inspection

When the inside of your drainage system has been compromised, an inspection with the naked eye is not an option.

Before technicians start working on relining the drain, they conduct a thorough examination of your drains using CCTV drain survey technology.

After identifying the extent of the damage and the exact location, they move to the next step – cleaning the drain.

Drain Cleaning

The drain and pipes are cleaned and de-scaled using high-pressure water jetting together with electro-mechanical machining.

Once the silt deposits, scales, debris or the cause of the blockage has been taken care of, the drains are then ready for refining.

No-Dig Drain Lining Installation

During installation, technicians insert a UPVC relining sleeve that is impregnated with resin through an opening in your drain into the drain.

A camera is also used to make sure that the relining sleeve is in the right position covering any holes, entry point for roots, cracks and misaligned joints.

The UPVC relining sleeve is then inflated using air inversion or water inversion to take the shape of the internal walls and lining over the damaged areas.

After curing (hardening), which could take up to three hours, the inflate sleeve is removed, and the relined drain section is cleaned to get rid of any excess resin solution.

Excavation (The Last Resort)

Sometimes technicians have no option but to turn to excavation to solve your drain problems.

If your drain has collapsed, then the only possible solutions on the table are either excavation or drain replacement if diverting the drain would be more cost-effective.

If plumbing technicians tell you that excavation is the only option, make sure to ask them to use CCTVs to identify the exact area with the problem. This way, the excavation can be done in the right spot.

The Advantages Of Drain Relining

Drain relining has many benefits, including:

  • It’s a non-destructive way to fix your drains
  • It’s a straightforward process
  • The lining is durable and can go for years without needing attention
  • Lining can work for pipes of all sizes
  • The lining creates a low friction surface, which aids water flow
  • Often cheaper than drain replacement

What Is CCTV Drain Inspection and Reporting Used For

Is your drainage system leaking and in dire need of repairs?

Are you wondering whether drain relining is fast enough to solve your drainage leakage problem?

Well, in this article, we will explore the matter of speed when it comes to drain relining.

We will delve into whether the process is fast enough to solve your leakage issues in a timely manner.

In a nutshell, drain relining is considerably faster than traditional methods of repairing drain lines.

Some of the factors that make drain relining a fast process include:

  • The relining installation process does not necessitate a lot of excavation,
  • The lining Installation and curing process is quick, and
  • The process of relining is precise.

No Need For Excavation

Drain relining is a generally a non-destructive trenchless technology used to repair damaged drain lines.

Generally speaking, the process does not involve excavation around the entire length of the drain line, thereby doing away with the need for repairing the intensive excavation process.

That said, you should note that there are cases where small access holes are excavated by the team of experts conducting the relining.

Examples of instances where access holes are excavated include when a plumbing system does not have a manhole or inspection chambers.

Additionally, when the manhole is quite far from the point of interest, an access hole may be excavated as well.

The access holes are designed to help the team of experts access the drain line and perform the relining process.

As such, the access holes are significantly smaller compared to the extensive excavation process that would result from excavating the entire line.

Consequently, the drain relining process is not only cheaper, owing to the lack of or reduced excavation but also significantly faster.

The Lining Installation And Curing Process Is Fast

Aside from the lack of or diminished need for excavation, drain relining as a process is generally fast.

Every stage of the process is not time-consuming and, therefore, makes the overall process, from start to finish, a quick process.

For instance, the inspection phase is aided by advanced CCTV drain line camera technology.

Using this technologically advanced tool reduces the overall time spent on identifying the problem areas and the extent of the problem.

When it comes to clearing and cleaning blocked drain lines, water jetting is the preferred method.

Not only is water jetting fast, but it is also effective. Mixing the epoxy resin is also an easy and fast process.

Finally, installing the lining is also fast.

After determining and cutting the required length of lining, the flexible resin is winched in, inflated in, or forced in place by high-pressure water.

The curing process is also fast. Typically, the technicians will use hot water or UV light to cure the lining in a matter of minutes.

Drain Relining Is Precise

The drain relining process typically uses advanced technology designed to optimise accuracy.

For instance, the live inspection feed from the CCTV inspection camera allows technicians to identify the location of the problem areas in a precise manner.

Moreover, technicians can cut the exact length of resin needed for the entire drain or section of waste pipe that needs relining.

All of these considerations contribute to making the relining process a fast and efficient method of drain line repairs.


When faced with a drain line leaking issue, relining is not only efficient and cost-effective but also fast.

The entire process takes considerably less time to complete than other methods.

Importantly, as a property owner, you do not have to sacrifice performance to accrue the benefits of fast repairs.

After the curing process, drain lines tend to have a robust structure that can last as long as 50 years.

Drain Patch Relining For Repairs

Do you have consistently unpleasant odours in your backyard for no reason?

Are you hearing constant gurgling noises even when all the taps are turned off? Do you have wet floors for no reason?

Please continue reading to learn more about why these things are happening and how to find a reliable solution for these problems.

If you are experiencing any of the above problems, this usually means that the drain pipes in your house are due for repairs.

Since the drain pipes are usually buried underground, it’s pretty hard to check them out to find the cause of the exact problem.

There are two options available to you when it comes to the repair of damaged drainage pipes.

One of the options is to excavate and replace the damaged drainpipes.

This is not only an extremely difficult process but also expensive, especially when drainpipes are buried deep under retaining walls or driveways.

Thankfully, there is another option which is known as drain relining.

About Drain Relining

Simply put, it’s a method of repairing the lining on drains.

It’s known by many other names including sectional pipe repair, no-dig drain relining, trenchless pipe relining, internal epoxy patching, drain rehabilitation and cured-in-place pipe among others.

This method of repair is widely used all around the world.

In this method, a new pipe which is known as lining is inserted inside the existing damaged pipe which turns it into a completely new pipe.

This repair method can be used for fixing radial cracks, circumferential cracks, leaking joints as well as open joints among other issues.

Drain patch relining is a similar process. In this method, a drain patch is used instead of relining the whole pipe with the help of a pre-shaped pipe.

In this case, an epoxy resin is used to fill up the spread out patch.

This patch is inserted into the damaged pipeline with the help of a tool called pipe packer.

The pipe packer is carefully and slowly inserted into the damaged drain.

Once the patch reaches the site of the defect, it is inflated and left there for around an hour before removal.

Around an hour of curing time is enough for the new patch to cover the leakage.

Drain patch relining is extremely effective when a full relining is not required and only a small damaged section of the pipe needs to be repaired.

The Process

The first step is the inspection. With this method, CCTV survey technology is used to determine the extent and location of the damage.

Once the inspection has been completed, cleaning is done in order to get rid of any obstructions.

If there are tree roots, a robotic cutter is used to remove such intrusions. This is followed by a high-pressure water jetter to clear any remaining debris.

Before relining, pipes are inspected again to ensure complete removal of all intrusions.

Once the pipes are clean, the type of pipelining and amount is decided.

Different situations call for different types of liners. In case of curved pipes, flexible liners are used.

As far as the installation process is concerned, there are various options.

In the inversion process, a resin is poured into the liner and it is evenly distributed.

Inflated airbags are then used after insertion of the liner into the damaged pipe in order to shape it to the pipe walls.

In some cases, water pressure is also used. Another method is UV pipelining.

In this method, cables and winches are used to pull the lining into the damaged pipe.

Installation is followed by the curing process. This ensures hardening of the inserted resin to keep the lining in its place.

In the case of the inversion process, the resin cures either by itself or hot water is run through the pipe to speed up the process.

In case of UV pipelining, UV lighting is used for curing.

Once the damage has been fixed, a final inspection is done to make sure that the repair process is complete.

Once again, CCTV survey technology is used along with leak detection equipment.


Drain patch relining offers a number of advantages in terms of lower costs, minimal disruption and high speed of repairs.

As far as the cost savings are concerned, drain patch relining is considerably cheaper when compared to excavation and replacement.

It is also an eco-friendly process as the lining and resin are environmentally friendly materials.

Trenchless Pipe Lining Technology

Imagine being able to repair leaks in underground pipes without the need to dig a trench? Well, the good news is that it can be done. Please read below for more.

Trenchless pipe lining is part of the broader trenchless technology.

In a nutshell, trenchless pipe lining is a type of subsurface construction and civil engineering technology that uses little to no continuous trenching in the installation of new and repairing and replacement of existing underground pipes, thereby reducing disturbance and the overall cost.

To understand this relatively new but increasingly popular technology, you need to delve into the following:

  • How trenchless pipe lining works (the steps),
  • It’s application,
  • The benefits of trenchless pipe lining, and
  • The reliability of the resulting pipe

How Trenchless Pipe Lining Technology Works

The trenchless pipe lining process consists of three phases.

The first phase is the preparation phase whereby the pipeline in question is removed from service, with a diversion or tanking feature installed in the meantime.

After that, the pipe that needs repair is thoroughly cleaned, typically using a combination of high-pressure jets and manual cleaning to get rid of debris and corrosion.

This ensures the lining will fit as close to the original pipe as possible, ensuring the lining pipe has ample capacity.

The specialists may also remove defective parts of the original pipe, especially when the pipe diameter has been negatively impacted.

The second phase is the lining process. During this phase, the Cured In Place Pipe Lining, saturated with resin, is winched or pulled in and installed in place.

The liner is inflated using compressed air or water under high-pressure.

Once in place, the liner is cured using hot water, steam, ultraviolet light, and in some rare cases, the liner is cured using ambient temperature.

The final phase is the post-curing stage. This stage comes after the liner has cooled and hardened in place. The end cuts are cut off and removed, leaving the pipe end flush and ready for sealing, if required.

The water used to cure the pipes is removed and disposed of safely. The final bit is to inspect and test the new pipe to ensure it meets the pre-determined specs.

The Application Of Trenchless Pipe Lining

Trenchless pipe lining is used to repair leaking, broken, and rusted pipes that are installed underground.

As such, the technology is used to repair pipes that are part of the sewer system, residential sewer plumb lines, and commercial sewer plumb lines.

The Benefits Of Trenchless Pipe Lining

Trenchless pipe lining technology yields a lot of benefits for everyone involved. For instance, homeowners get access to less expensive pipe repair and replacement services.

Pipelining costs as much as 50% to 70 % cheaper when compared to the excavation process.

Homeowners also do not have to incur the hassle and the costs associated with excavating concrete installations such as walls and floors.

Trenchless pipe lining is also a clean pipe repair process as specialists do not have to excavate the leaking pipe.

It is also a faster way of repairing and replacing leaking old pipes – after all, there is no trenching needed.

Given that it is a fast and safe solution, property owners or occupants need not move out for the pipe renovations to take place.

On the other hand, other people in the vicinity of the project benefit from an environmentally friendly process of repairing plumbing lines.

They do not have to worry about grey and black water leaks affecting their environment.

Trenchless pipe lining technology allows service providers to render cost-efficient services. They can, therefore, attract more clients and retain most of the clients they get.

The Reliability Of Installed Pipes

Depending on the environment, the pipe lining can last as long as 50 years. After the inner lining cures, the resulting pipe is solid.

In fact, the pipe can stand alone and function as a pipe without suffering from structural integrity deficiencies.

Moreover, the lined pipe can withstand load bearing from the soil covering it, foot traffic, and even vehicles.


Trenchless pipe lining technology has revolutionised how underground pipe installations are maintained, repaired, and replaced.

The technology reduces the amount of time it takes to repair underground installation while yielding high-quality pipes that last long and are fit for purpose.
