4 of the Best and Most Popular Trenchless Repair Technologies Today

Majority of applications used in sewer pipe repair today are done through trenchless methods. The reason why many repair contractors prefer trenchless applications is due to the fact that it requires less labour and use of heavy-duty equipment. Furthermore, the time required to complete a repair project is faster than standard repair methods. Trenchless is also good for property owners since the solutions used don’t damage the properties heavily as opposed to traditional open cut excavation applications in the past.

There are two distinct classifications of trenchless. These are pipe rehabilitation and pipe replacement and each one of these have branching applications. Get to know more about the best and popular trenchless repair technologies used today.

  1. Pipe relining through Cured-in-Place-Pipe or CIPP

CIPP is probably the most popular method in trenchless sewer line repair technology. It has everything you wished for a pipe repair. It doesn’t distort or damage the site of repair and property. CIPP can also be completely finished in just a matter of days. It’s also a great long term investment since it repairs and improves the old or damaged pipeline.

CIPP is done by conjoining a resin liner into the old pipe. The resin liner is clay-like in form and bonded with the inner lining of the pipes to fill in voids and cracks. The liner is then solidified fast by applying hot water or steam onto it. This liner also improves the sewer system since the resin improves the flow of wastewater and prevents root attacks. Excavation may be needed for some areas that are difficult to insert the resin liner. Only one access point or pit is needed to integrate the liner into the pipes.  

The resin liner is durable and can last for 100 years; provided the material is top quality. Pipe relining is truly an impressive trenchless technology but it’s impossible to apply in every sewer pipe repair. CIPP can’t be used on pipes that are too weak or damaged since the resin won’t be able to attach well onto it.  

  1. Pull-in-Place Method

This is another form of relining which is more or less the same with CIPP. A resin liner is still used to repair and augment the old pipeline. The main and only difference between the two is how the liner is placed into the pipes. Pull-in-place method requires two access points while CIPP requires only one. The pull-in-place repair pulls the liner into the desired location through the two excavation pits.

  1. Moling

The two mentioned above are pipe rehabilitation methods. Moling is different in its own ways since it’s a replacement solution. Unlike an open-cut excavation, moling is less damaging to property since an excavation pathway is directly dug through the pipeline. This eliminates the need for digging out an entire pipe section just to remove a pipe and place a new one.

  1. Pipe Bursting

This is another pipe replacement method that has become pretty popular lately. The pipes are purposely broken into tiny pieces to allow the new pipe to be pulled through the pipeline. Pipe bursting also causes nominal property damage since digging is kept at minimal. This particular method is also used to widen a pipeline for the installation of a bigger pipe.
