OVERVIEW
What is epoxy pipe lining?
Epoxy pipe lining refers to repairing and restoring old and damaged pipes with a new pipe made from two-part epoxy. It is a no-dig/non-invasive method that essentially creates a new pipe inside the old pipe without any excavation necessary. The result is a tight-fitting, jointless, and corrosion-resistant pipe.
Epoxy pipe lining may also be referred to as CIPP sewer lining, trenchless pipe relining/pipe lining, or trenchless sewer repair, among many others. These are the most common names for installing a new structural pipe material inside an original pipe without having to tear down walls, dig, or excavate around the pipe.
This guide will guide you through the process and teach you everything you need to know about epoxy pipe relining.
COMPARISON
Epoxy pipe lining vs. Repiping
Repiping is the traditional pipe repair method by which old pipe systems are replaced by a new one and requires the contractor to excavate around the pipe. In recent years, epoxy pipe lining has gained popularity and is slowly but surely becoming the standard for pipe repairs due to its many benefits.
Not only is the epoxy lining method less invasive, with a less destructive process, ensuring the owners of the building won’t have to relocate or stop their operations during the restoration. It is also a significantly more cost-effective process as the relining products and tools cost considerably less than the heavy machinery required for repiping.
Installing an epoxy liner for sewer and plumbing systems usually only takes a few hours up to a few days – depending on the project size – while repiping can sometimes take weeks to complete. Ultimately, it depends on the extent of the job and the amount of demolition required.
HOW IT WORKS
How is an epoxy liner for sewer and plumbing systems installed?
The epoxy pipe lining method is performed in four steps:
- First, the pipes need to be cleaned and descaled to expose damages, but also to expose and open the old pipe to its original inner diameter to make room for the new epoxy lining. If any scale is not removed, important clues crucial to a successful epoxy lining installation may be overlooked. In the end, inconsistent cleaning leads to inconsistent installations.
- The lining is carefully and fully saturated with two-part epoxy.
- The epoxy lining is placed in the old pipe using either the pull-in-place method (for sectional or remote installs, tee, wye, and straight liners) or the inversion method (for longer installs). Regardless of the method, the epoxy will always be on the outside of the liner. Air pressure ensures the epoxy lining fills out the original pipe completely.
- Once the liner is in place, heat is introduced to speed up the curing process of the epoxy using either hot water or steam. During this process, the epoxy resin hardens, leaving a seamless, smooth, and corrosion-resistant new pipe. Curing an epoxy liner inside a sewer or plumbing system may also be cured passively; it takes longer, but yields just as good of a result; this is referred to as “ambient curing”.
When installing the epoxy pipe lining above ground, it is important to install them in the flow of water, overlapping each other. This is to prevent the risk of sewer or drain water leaking behind the new lining material over time. This way, we can optimize the new epoxy lining system’s lifetime without seal-failure due to poor adherence, which is always a risk when working with old pipes.
METHOD
The Repiper StepbyStep 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
Advantages of the Repiper StepbyStep epoxy relining method
The Repiper StepbyStep epoxy pipe lining method provides a host of advantages to the benefit of both the owners of the building and the relining company:
- Less invasive. Epoxy pipe lining eliminates infiltration and leaks in pipes without having to dig or excavate walls or floors. It ensures the building owners won’t have to evacuate, a critical aspect for businesses to avoid disruption in their daily operations. Due to it being a non-invasive solution, it is frequently used to repair pipe systems in buildings with historical value.
- Saves time and money. The fact that no excavation or demolition is required makes the epoxy pipe lining method more cost-effective and less time-consuming than traditional repiping.
- Scalable. The Repiper StepbyStep method is more scalable than traditional pipe restoration methods as it does not require any big and heavy robots, machines, or equipment to repair the pipes.
- Environmentally friendly. There is little to no waste to dispose of with the epoxy pipe lining. Structurally fine parts of the building remain untouched since the work is done remotely inside the pipe through accesses such as vents or cleanouts.
- Increased quality. Epoxy lining creates a smoother pipe which increases the flow capacity and ensures that calcification deposits won’t stick. It is also corrosion-resistant, which greatly increases pipe’s longevity.
