OVERVIEW
What is trenchless pipe lining?
Trenchless pipe lining is a method to repair and restore existing main, lateral, and vertical sewer and drain pipes. The “trenchless” part comes from the fact that it is non-invasive/”no-dig”; in other words, walls and floors will not have to be removed to perform the work. Trenchless pipe lining involves lining pre-existing pipe systems with tight-fitting, jointless, and corrosion-resistant replacement pipes and their fittings made out of cured epoxy.
Trenchless pipe relining/pipe lining/plumbing, CIPP sewer lining, epoxy pipe lining. Whichever word you are familiar with, they all refer to the same thing as described above.
COMPARISON
Trenchless pipe lining vs. repiping
Repiping refers to completely replacing old, damaged, or broken pipes. It is slowly but surely being phased out, replaced by the trenchless pipe lining method for multiple reasons – and with good reason. The trenchless method provides advantages for both the contractor and the end customer whose pipes are being replaced. The advantages include, but are not limited to:
- Less invasive. Trenchless pipe relining does not require the contractor to demolish or remove walls or floors. Traditional repiping involves acute inconvenience for the owners of the building. The buildings will have to be evacuated or the owners will have to deal with noise and dust while the restoration of the pipes is in progress.
- Cost-effective. The total cost of repiping exceeds the trenchless pipe lining cost since the pipe lining is cheaper than new pipes, and the cost of remediation (repairing walls/floors/structures and repainting) is completely eliminated.
- Time-effective. Trenchless pipe lining can take a few hours up to a few days to complete. Repiping can sometimes take weeks to finish. It ultimately depends on the extent of the job and the amount of demolition required.
HOW IT WORKS
How trenchless pipe lining works
Trenchless commercial sewer line repair is performed in four steps:
Step 1 – Cleaning the pipes
The first step is to clean the pipes and descale them to expose any damages, but more importantly, to expose and open the old pipe to its original inner diameter. If any scale is left, important clues crucial to a successful lining install might be overlooked. In the end: inconsistent cleaning leads to inconsistent installs.
Step 2 – Saturating the liner
Once the pipes have been cleaned, the liner is carefully and properly saturated with a two-part epoxy.
Step 3 – Installing the liner
The liner is placed in the pipe using either the pull-in-place method or the inversion method. The pull-in-place method is primarily used for section or remote installs, tee, wye, and straight liners, while the inversion method is used for longer installs.
Air pressure is applied to ensure the liners fill out the original pipe completely. Regardless of the method, the epoxy will always be on the outside of the liner.
It is important to install new liners in the flow of water, overlapping. This is to prevent the risk of sewer or drain water getting behind the new lining material over time. This way, the lifetime of the new relining inside is ensured without the risk of seal-failure due to poor adherence in the old pipes.
Step 4 – Curing the liner
The last step, once the liner is in place, is to cure the liner. Heat is often introduced to speed up the curing process of the epoxy, either by using hot water or steam curing. During the curing, the epoxy resin hardens to create a seamless, smooth, structurally sound, and corrosion-resistant new pipe inside the old pipe.
The liner can also be left to cure by itself without heat, this is called ambient curing. The only downside of this is that it will take longer to cure.

ADVANTAGES
Advantages of the Repiper commercial sewer repair method
The Repiper StepbyStep method provides multiple advantages for the owners of the building as well as the relining company:
- Non-invasive. The Repiper method eliminates leaks in pipes without having to dig or excavate. While this is important to normal homeowners, it is critical for businesses to avoid disruption to their operations. Relining is also the method of choice when pipe systems in buildings with historic value need to be repaired.
- Saves time and money. The fact that no excavation or demolition is required makes the Repiper trenchless pipe lining method both more cost-effective and less time-consuming than traditional methods.
- Scalable. The Repiper StepbyStep method is more scalable than repiping because it does not require any big and heavy equipment to repair the pipe system. Pretty much any relining company, regardless of size, is able to execute it without any significant investments.
- Environmentally friendly. There is little to no waste after a completed relining project. Structurally fine parts of the building remain untouched since the work is performed inside the pipe through accesses such as vents or cleanouts.
- Increased quality. As the epoxy lining creates a smoother pipe inside the old pipe, it increases the flow capacity while preventing calcification deposits from sticking. It is also corrosion-resistant, which greatly increases the pipes’ longevity.

FAQ
How long does it take to do trenchless pipe lining?
The time it takes to reline a pipe using trenchless pipe relining techniques can vary depending on factors such as the length of the pipe, accessibility, and the specific circumstances, but it typically ranges from a few hours to a couple of days.
Can you reline a cast iron pipe?
Yes, cast iron pipes can be relined using trenchless pipe lining methods.
How long does drain relining last?
Drain relining can last anywhere from 50 to 100 years or more, depending on various factors such as materials, pipe condition, and maintenance.
What is the most common material used for trenchless repair?
The most common material used for trenchless pipe relining is cured-in-place pipe (CIPP) lining, which involves inserting a liner coated with a resin into the existing pipe and curing it to create a new, seamless pipe within the old one.
Why would you reline a pipe?
Relining a pipe is done to repair damage, restore functionality, extend lifespan, prevent future issues. Trenchless pipe lining is also a very cost-effective and environmentally friendly alternative to traditional pipe replacement methods.
Can trenchless sewer repair fix a belly?
Yes, trenchless pipe lining methods can be used to fix a belly in a sewer line.
Can you fix a leaky pipe without replacing the pipe?
Yes, trenchless pipe relining is a great way to fix a leaky pipe without having to replace the old pipe.
Which pipe is the best for underground drainage in home?
High-density polyethylene (HDPE) pipes are commonly considered one of the best options for underground drainage in homes due to their durability, flexibility, and resistance to corrosion and chemicals.
