What is Pipe Relining and How Does It Work?
Pipe relining, also known as Cured In-Place Pipelining (CIPP), is a method by which you can replace your pipelines without the excess costs associated with having to dig up and replace existing pipelines.
Your piping infrastructure is probably one of the most dreaded parts of your home. Even worse is the supposed nightmare of having to replace pipes which give in due to use over time. However, there is an easier way out, even if the internal damage to your pipes seems substantial.
What is Pipe Relining?
Pipe relining attempts to repair your pipes by curing them from the inside using a special resin, which cures with time in order to form another strong (in some cases, even stronger than the original) pipe.
In this method, the resin is the key to curing the pipe. A resin-saturated felt tube made out of a suitable material (generally polyester or fiberglass) for resin impregnation, is inserted into a damaged pipe. This resin then hardens and forms another pipe within the damaged pipe.
The insertion takes place from an access point which is upstream. Inserting from a downstream access point is possible, but it is riskier and hence avoided.
Pipe relining is considered a trench-less technology, since minimal to none digging is involved in this trench-less process. This makes relining a more cost-effective and less intensive method than traditional “dig and replace” pipe repair methods.
How is Pipe Relining Done?
There are many stages to pipe relining, which are as follows:
First, the pipes are checked and inspected to examine the extent of the damage to them. This was traditionally done with the help of closed circuit cameras, but now forced electron leak location (FELL) equipment is used to examine the damage more closely to design better solutions.
The next step involves cleaning of the blocked pipes, which is has multiple steps. Firstly it is cleaned using regular methods, and then any solid or large blockages are removed. Typically robotic cutters are employed. Lastly, a high pressure water jet is used to finish up cleaning and ensure a good surface on the pipe walls for the resin to set.
Then, another final check is performed in order to make sure that the pipes are ready to be relined, typically using closed circuit cameras.
Now, the length of the lining is determined from the length of the pipes, as well as the extent of the damage to them.
After determining the length of the pipe, the pipe is saturated with epoxy resin. This implies that the entire length of your pipes will be filled with the resin which would become the pipe after curing. Straighter and wider sections of the pipe are easier to deal with than tricky joints and T-sections in this phase.
This step is followed by the curing process, which is the longest step in the entire process. This step can be either performed by letting the lining cure manually, but generally hot water is used to accelerate the process. Finally, UV radiation is used to take the cured lining to complete hardness.
Before completing the process, all the junctions and inspection pits are cut. This process uses robotic cutters to remove junctions, however, inspection pits can be dealt with using grinders or any surface level cutters.
Finally, the pipe relining process is now complete. There must be checks performed, so make sure your pipes are working well just after the final checks have been completed by the pipe relining service you hire.
What are the benefits of pipe relining?
There a number of benefits attached to going in for pipe relining, rather than going for the whole “digging-a-trench and replacing the pipe” process. These include, but are definitely not limited to the following.
Limited landscaping problems
Digging up drains to repair affected pipe sections leads to major upheavals of the landscape.
Further, a lot of the flora, which binds the ground and takes years to grow is destroyed. Ground covering materials need to be removed permanently. These must be replaced after repairs are completed. The replacement process might take months or even years. All the work above adds substantial peripheral costs.
Going in for relining implies minimal disruption occurs to the surface. Your home remains mostly untouched while you get pipes which are as good as new, sometimes even better than a set of new pipes.
A disrupted ground surface poses a big risk to the residents, which is magnified if the building has multiple occupants (say an apartment building). Trenches, debris and holes make for vulnerable accident spots. It also becomes a hindrance in movement. Children, the elderly and pets become especially vulnerable to accidents. Pipe relining is easily the safer option, presenting none of the problems states above.
Cost effectiveness and value addition
A well designed drainage system is a definite plus in adding resale value to your home. Since a new plumbing system working equally as well is going to cost you a lot more, this automatically makes relining the better choice.
It involves much lesser labor costs as well as peripheral costs in rebuilding the green cover, the ground trenches, etc.
The addition of the resin pipe into the old pipe reinforces the piping system.
Hence, you effectively end up with two pipes within one plumbing unit. The weaker points and joints of the system are also eliminated.
Faster to repair
Compared to digging trenches and laying new pipes, relining is a much faster process. Relining is also able to deal with harder-to-access areas in a much easier and faster manner. Your living environment also becomes more normal much faster.
Another advantage of relining is that the installation time associated with relining is a fraction of the time required to lay new pipes.
Factors to Take Care of Before Relining
Pipe relining can work in the vast majority of cases, provided there are enough precautions taken beforehand. However, there are a few cases where pipe relining has physical limitations, so keep these in mind.
These limitations include:
Smaller diameters (less than 4 inches) can present trouble, because epoxy needs some area to harden. For smaller pipes, this is not always possible.
Uneven cleaning, which causes uneven linings to form. These can cause severe problems later. Make sure the cleaning is done properly, and even over multiple iterations if once is not satisfactory. Debris can also cause trouble during relining.
Broken pipe components, which will have to replaced in any case. No amount of lining can create a new outer pipe for you, so make sure that the outer surface of the pipe is good enough before relining.
Joints and tricky bends are harder to handle using epoxy resins. These are easier to deal with using new joints and bends rather than the epoxy taking their shapes.
Is Pipe Relining a Long Term Solution?
It is easier to assume that relining, being a second pipe within a damaged pipe, would naturally be less resilient than going in for a fresh set of pipes.
Fortunately, this assumption is unfounded by the reality of stability of the relined pipes.
In many cases, pipe relining is a much longer-term solution than actually replacing the pipes. Pipe relining come with warranties ranging from ten years up to the more common fifty years of trouble-free drainage, which gives you a fair idea of how well relined pipes really work.
However, much depends on the relining service you choose. Certain pipe relining services will offer you better services than others in terms of service as well as the warranty that is provided. Hence, it is crucial to research well before going in for a particular pipe relining service.
Do My Relined Pipes Need Testing?
There are a number of standards according to the country you reside in, so make sure you get tests done in order to make sure the building materials are safe to use, and will last long.
Make sure your suppliers have been certified according to the building standards, and that quality checks have been performed on the materials being used across the entire process.
Ideally, there are some factors for which your relining supplier must have testing results for. They are listed as follows. Make sure you ask for the testing results before you decide on going for a relining job.
A few of the factors that your relining supplier must have valid credentials for are:
Flexure – This is also called bending stress, and is a measure of the pipe’s ability to bend before it breaks.
Compression – This factor is related to the reliability of compression fittings.
Flow rate – This factor relates to the maximum rate at which water and sledge can flow through the pipe, before they cause any damage.
Concrete beam – This relates to the strength of concrete beams of the structures surrounding the pipes, or which the pipes may be present in.
Abrasion – This refers to the overall abrasive cleaning of the pipes before relining.
Asking for testing results can be the difference between a few years before the relining gives in, and fifty or more years of lasting relining.
Putting it all together
Pipe relining is a wonderful alternative to what would be weeks or even months of laborious, intrusive repairs, costing you dearly both in resources and labor. Make sure your pipe relining service – or you, if you’re inclined towards a DIY plumbing job – follow(s) the steps as they have been outlined.
Taking cognizance of the pipes before they’re too far gone is the best way of making sure that your pipes can be relined, thus saving you a lot of money, time and stress.
Further, make sure you’re aware of when and when not to use relining, to maximize the benefit you derive from it. Making sure that the job is being done properly can lead to many, many years of trouble-free drainage!

Some signs to watch out for:
Sewer Gas Odor – One key sign you may have a leak in your sewage line is noxious odors. If you suddenly smell unpleasant sewage, it is important you call for help.
Slow Drains – Leaks in your drains and lines can back up the water, causing drainage to slow down. If left untreated, this can cause clogs and compromise the integrity of the pipe.
Extra Lush or Green Grass – Is there one area in your yard that is particularly lush? This might indicate a leak in your sewage line, creating additional fertilization.
Rodents – If you suddenly experience an influx of rodents, your sewage and drains might be the cause. Make sure they are well sealed to protect your home and family.
