A 101 On Underground Pipe Repair

underground pipe repairSome people have DIY plumbing skills so they handle repairs on their own. While there are simple issues that you can personally manage, such as repairing leaking faucets or replacing shower heads, you should know that there are also jobs that should only be done by professionals. Some of these include water heater repairs; septic tank maintenance; pump-outs; sewer cleaning and of course, underground pipe repair. Underground pipe repair requires the use of special tools and equipment that can only be operated by trained professionals. The pipes are also buried deep under the ground which makes the job even more complicated. Definitely, plumbing experts aim to repair the pipelines but are also careful in order to avoid accidents and prevent damages on the property.

How do professionals repair underground pipes?


There are several ways that underground pipes are repaired. In general, plumbers fix pipes using either “trenchless” or “dig and replace” methods. The dig and replace method involves the excavation of the pipes and their replacement. If the underground pipe is located in the yard or not necessarily under your home or any structure, the dig and replace method is alright. However, if the affected pipes are under your home and are not accessible, the trenchless method is the better option. Here are some techniques used by professionals:

1. Pipe Bursting – Pipe bursting involves the breaking off of the affected pipe from its inside. The prime purpose of this method is to force fragments out and then finally install a new replacement.

2. Slip-Lining – Slip-lining is best for taking care of leakages or restoring the pipelines’ stability. This method involves the insertion of a smaller PVC pipe that fiberglass-reinforced inside the affected line. To cover the space between the two pipes, grout is applied between them. This can be accomplished continuously or in segments.

3. Cure-in-Place Piping (CIPP) – CIPP is the pulling or inverting of a polyester pipe, a fiberglass cloth or any other sustainable material inside the pipeline. This is done with the use of air pressure or water.

4. Mechanical Spot Repair – Finally this trenchless pipe repair method involves the repair of the affected area in order to give the pipeline renewed stability.
