Major Forms of Trenchless Pipe Repair

Traditional pipeline repair is often associated with piles of rubble, dug up roads and sidewalks, unpleasant smells, and excess waste. Luckily, modern trenchless pipe repair methods get the job done with no destruction. Trenchless repair methods offer an easier, cheaper, and faster way to get pipelines up and running again. Here are some of the major forms of trenchless pipe repair.




One of the oldest trenchless repair methods is slip lining. The method involves slipping a small diameter pipe into a larger, damaged pipeline. This reinforces and strengthens the old pipeline without having to dig massive trenches. While slip lining is still used to fix some pipelines, this method has largely been replaced by cured-in-place pipeline repair.




Cured-in-place pipe repair, or CIPP, is one of the most common methods of trenchless pipe repair. Instead of putting a new pipe inside the damaged old pipe, CIPP utilizes a liner. Applying a liner allows for the pipe to maintain its current flow rate. This method of pipe repair is utilized on structurally unsound and leaking pipes in order to repair them without having to actually remove the old pipeline.


Pipe Bursting


Pipe bursting is a method used to replace pipelines without having to remove the old one. This process involves fragmented the old pipe in order to install a new one. It’s done by pushing a bursting head through the damaged existing pipeline. As the bursting head progresses through the pipe, it pushes the shattered pieces into the surrounding soil. This creates space for a new pipeline to be installed without having to dig.


With more and more people choosing trenchless pipe repair, it’s important to know the major methods. In order for a repair method to be considered trenchless, it has to fix pipelines without digging into the ground or walls. Three of the major forms of trenchless pipe repair include slip lining, cured-in-place, and pipe bursting. Each of these methods provides its own benefits when it comes to trenchless pipe repair. Next time your pipelines need to be repaired or replaced, contact the professionals to find the right trenchless pipe repair method for you.
