Discover the benefits of epoxy pipe lining, a trenchless method for restoring old and damaged pipes from the inside. Repiper’s epoxy pipe relining solution creates a seamless and corrosion-resistant new pipe with minimal excavation and disruption.
OVERVIEW
Epoxy pipe lining refers to repairing and restoring old and damaged pipes by installing a new pipe made from two-part epoxy inside the existing pipe. It is a no-dig method that creates a new pipe within the old one, reducing the need for excavation, demolition or access to the full pipe route.
The result is a tight-fitting, jointless and corrosion-resistant internal pipe. Epoxy pipe lining can be used to seal cracks, leaking joints and deteriorated internal surfaces when the existing pipe remains suitable for relining.
Epoxy pipe lining may also be referred to as CIPP sewer lining, trenchless pipe relining, pipe lining or trenchless sewer repair. These terms describe methods of installing new structural pipe material inside an existing pipe.
The epoxy pipe relining process helps restore the pipe’s function while extending the useful life of the existing system.
COMPARISON
Repiping is a traditional pipe repair method in which the existing pipe system is removed and replaced. This normally requires access to the full pipe route and may involve opening walls, floors or surrounding surfaces.
By contrast, epoxy pipe lining repairs the pipe from the inside. Relining pipes with epoxy allows the existing pipe route to remain in place while a durable new lining is created within it.
The method can reduce excavation, demolition and restoration work. It can also limit disruption to buildings and operations during the repair.
Installing an epoxy liner in sewer and plumbing systems may take from several hours to several days, depending on the size, accessibility and condition of the pipe system. Traditional repiping may require more time because the existing pipes and affected surfaces must be removed and restored.
HOW IT WORKS
The epoxy pipe lining method is performed in four main steps:
1. Cleaning and preparation
The pipes are cleaned and descaled to remove deposits, corrosion and loose material. This exposes damage and restores the pipe as closely as possible to its original internal diameter, creating sufficient space for the new lining.
Consistent cleaning is important because material left inside the pipe may affect the quality and fit of the completed installation.
2. Liner saturation
The selected liner is carefully saturated with two-part epoxy. The amount of resin and liner dimensions are determined according to the pipe diameter, length and installation requirements.
3. Liner installation
The epoxy-saturated liner is installed using either a pull-in-place method or an inversion method, depending on the pipe configuration and project requirements. The epoxy remains on the outside of the liner, while air pressure expands the liner against the internal walls of the original pipe. This is the central stage when relining pipes with epoxy.
4. Curing
Once positioned, the liner is cured using the selected curing method. Heat may be introduced through hot water or steam to accelerate the process, while some systems may be allowed to cure at ambient temperature.
As the epoxy hardens, it forms a seamless, smooth and corrosion-resistant new pipe inside the original one. For an epoxy sewer pipe lining installation, correct positioning, curing and final inspection are essential to achieving a consistent result.
When epoxy pipe lining is installed above ground, individual liners should be positioned according to the direction of water flow and correctly overlapped. This helps reduce the risk of sewer or drain water passing behind the new lining material.
METHOD
The Repiper StepbyStep method is a superior relining solution for residential, industrial, and commercial small-dimension sewer repair. We offer guidance and all the necessary relining tools and products to carry it out. Using our method, products, and tools, the entire epoxy pipe lining process only takes a few days and is carried out at a fraction of the cost of traditional methods.
ADVANTAGES
The Repiper StepbyStep epoxy pipe relining method offers several advantages compared with traditional excavation-based pipe replacement.
Less invasive
Epoxy pipe lining repairs the pipe from inside the existing system, reducing the need to open walls, floors or surrounding surfaces. This helps limit disruption in occupied buildings and properties where extensive demolition should be avoided.
Saves time and money
Because less excavation, demolition and restoration are required, epoxy pipe relining can reduce project time and associated repair costs compared with conventional repiping.
Scalable
The Repiper StepbyStep method does not require large excavation machinery or heavy pipe-replacement equipment. This allows the system to be used for suitable projects with different access conditions and installation requirements.
Reduced material waste
Much of the existing pipe and surrounding structure remains in place. This reduces the amount of removed pipe material and building waste that must be transported and disposed of.
Improved internal pipe surface
The cured epoxy liner creates a smooth and continuous internal surface. This can improve flow conditions, reduce locations where deposits may collect and protect the repaired surface from corrosion.
The final quality of epoxy relining depends on correct inspection, cleaning, liner preparation, installation and curing.

What is epoxy pipe lining?
Epoxy pipe lining is a method of repairing damaged or deteriorated pipes from the inside. A flexible liner saturated with epoxy resin is installed within the existing pipe and cured to form a smooth, continuous and corrosion-resistant new internal surface.
How does epoxy pipe relining work?
The existing pipe is first inspected and thoroughly cleaned. An epoxy-saturated liner is then inserted, expanded against the pipe walls and allowed to cure. Once hardened, the liner forms a new pipe inside the original one.
What types of pipe damage can epoxy lining repair?
Epoxy pipe lining can be suitable for repairing cracks, leaking joints, corrosion, small holes and worn internal surfaces. The existing pipe must retain sufficient structural stability, so a camera inspection is required before installation.
Can epoxy pipe lining be completed without excavation?
In many cases, yes. Epoxy pipe relining is a trenchless method because the liner is installed through existing or local access points. Some access work may still be necessary depending on the pipe location, layout and condition.
What is an epoxy liner for sewer pipes?
An epoxy liner for sewer pipes is a flexible lining material saturated with two-part epoxy resin. It is installed inside the existing sewer pipe and cured to create a strong, seamless new internal pipe surface.
How long does epoxy pipe lining take?
The installation time depends on the pipe length, diameter, condition, accessibility and curing method. Relining pipes with epoxy can often be completed faster than traditional replacement because extensive excavation, pipe removal and restoration are reduced.
Is epoxy pipe lining the same as pipe coating?
No. Pipe coating applies a protective layer to the inner surface of a functional pipe. Epoxy relining creates a new structural lining inside a damaged or deteriorated pipe and is intended to restore its function.
Does epoxy pipe lining reduce the internal pipe diameter?
The liner slightly reduces the internal diameter of the original pipe. However, the cured liner creates a smooth and jointless surface, which can support efficient flow and reduce areas where deposits may accumulate.
