Comparing and contrasting Trenchless Pipe Rehabilitation and Pipe Replacement
Before proceeding and reading more of the article, please take note that in referring to pipe replacement, we’re talking about trenchless pipe methods instead of traditional ones that mainly involve open cut excavation. Anyway, you can learn more about pipe rehabilitation and pipe replacement as well as when these applications will be better suited by reading the contents below. But before anything else, this article will discuss some of the basic principles and methods in both pipe rehabilitation and pipe replacement.
Pipe rehabilitation basically repairs or restores the structural integrity of a pipeline by adding a pipe liner, pipe carrier, or any other pipe-like structure into the current pipeline of the sewer system. There are a lot of pipe rehabilitation methods out there, but the most notable ones are cured-in-place-pipe(CIPP), pull-in-place-pipe(PIP), slip lining, and among others. Pipe rehabilitation is favoured by both plumbing companies and even pipe repair contractors because of many of reasons, one of which is the fast turnaround time in completing the project. Aside from that, there is also nominal damage done to the surroundings, and there are even times in which the destruction is non-existent. With less interruption and excavation, the hazards posed in excavating is reduced or completely eliminated. Lastly, the pipe liners or carriers that are inserted into the host pipe are durable and can last a long time–it’s basically as good as if you placed a new set of pipes into the sewer system, minus the inconvenience and destruction around the work site. The new pipe structures that are applied into the sewage system aren’t just typical pipe materials since it doesn’t only enhance the structure of the linings but also thwart common and annoying issues with sewer pipes such as tree root attacks, leaks, and rusting.
Trenchless Pipe Replacement
Trenchless pipe replacement is more of the enhanced version of conventional pipe repair method. The trenchless applications usually have 90-95% less disruption compared to open cut excavation pipe repairs, and are also done at a faster rate. Also, there are many varying methods that belongs to trenchless pipe replacement such as pipe bursting, moling, etc. Using the right kind of method will ensure that the pipe replacement will be done quickly with minimal disturbance to the work site. It’s clear that pipe relining seems more favourable than using trenchless pipe replacement even with its huge improvement from its old counterpart, but there is a reason why pipe replacement is still used today.
Relining or Replacement?
With all the benefits and features of pipe relining, some of you may think that this is more of a preferable solution than replacing sewer pipes. However, there are certain cases in which relining won’t be any help in improving or repairing the damaged sewer line. Pipe relining won’t be able to fix pipe sections that are installed improperly, fill incredibly great voids in host pipes, enlarge the diameter of the pipes, and many more. These are just a few reasons why pipe replacement can be the only sensible solution for certain sewer pipe problems.
