The Different Kinds of Sewer Line Repair Technology

Modern sewer line repair technology is far more superior to traditional pipe repair methods. Some of the new age pipe rehabilitation applications have minimal environmental damage. In fact, there are even methods that don’t need any excavation. Read more to learn about these different kinds of sewer line repair technology.  


Cured-in-place pipe (CIPP)

CIPP is highly effective in repairing pipes that needs to have its durability improved. It’s also one of the fastest rehabilitation methods out there. The whole concept of this repair technology is quite simple; a new and high quality liner is inserted into an aged pipe system which covers the leaks and damage while improving the flow efficiency. Only one entry point is needed and it doesn’t require any form of excavation unless some parts of the pipes must be manually removed.  The inserted pipe liner is usually cured or hardened with a high pressure steam. But before introducing the new liner, the old pipes must be first cleansed with a high water pressure from a hydro jetter. There may be trouble applying CIPP to pipes that are heavily damaged or are almost collapsing.



In this method, two holes are created to serve as the entry and exit point of the inserted liner. The liner used is fiberglass and resin which is secured in a cable. It is then pulled into the pipe and is tightly attached into the tube which serves as the holder of the pipe. Static pressure is applied to the tube so that it will become inflated and allow the liner to be attached to the current pipe. Just like CIPP, pull-in-place liners can also be cured with high pressure steam.



This is one of the few sewer lines repairs that always require digging and has the possibility to distort the surroundings. Moling requires trenches to be dug so that the new pipe can be installed into the sewer system. Although it does cause a minimal amount of damage to the landscape, this sewer repair technology is actually effective in replacing new pipes. You see, there are certain occasions in which a damaged pipe can’t be repaired anymore and thus, a new pipe must take its place. Moling makes use of a specialised digging equipment to create a new path for the pipe. After the trench if finished, the pipe is easily placed into the sewer system. Moling is definitely better than conventional pipe replacement since it has nominal excavation and can be done faster.


Pipe Bursting

There are cases when lining won’t help the old pipe from certain destruction, and the only solution is to just get a new pipe and replace the old one. Pipe bursting is another sewer line repair technology that can change the new pipe. Openings are created into the pipe that is about to be replaced. A cable is then inserted to each end of the old pipe together with a PVC or HDPE section of the pipe. After that, the bursting head is then pulled and causes a bursts which immediately replaces the old pipes with the new one.
