Trenchless pipe repair and cleaning has become more and more popular over the past decade. This is due largely to the fact that trenchless pipe replacement intervention has the ability to offer a number of substantial benefits. One of those benefits is that it may not require the excavation of existing pipes, which means that it’s less intrusive than other methods. Here is what you need to know about trenchless pipe repair and relining

What Is Trenchless Pipe Repair

In the plumbing industry, trenchless pipe repair is a process that allows plumbers to perform repairs in the ground without digging. This process uses a variety of methods, such as pipe bursting, pipe lining, and pipe relining, to replace or repair damaged pipes. Trenchless pipe repair involves removing the damaged section of the pipe and inserting a new piece of pipe. The new piece of pipe is connected to the existing pipes with epoxy or another adhesive material. The trenchless method of repairing pipes has become popular because it offers several advantages over traditional digging methods.

How Does Trenchless Pipe Repair Service Work

Commercial building trenchless pipe repair is a great option for businesses because it can be done in a matter of hours. It also has an excellent track record of longterm success. The process of trenchless pipe repair includes the following

1. The Pipe Is Inspected and Cleaned 

The pipe is inspected for damage using a video camera. The inside of the pipe is cleaned out with a highpressure water jetter, which removes any dirt or debris that may be blocking it

2. A New Liner Is Pushed Through the Pipe 

The third step in trenchless pipe repair is pushing a new liner through an existing pipe. This liner is made from a flexible material that can expand and contract as necessary to fit snugly inside the pipe. When it is inflated, it will expand to fill any gaps and create a tight seal against both sides of the pipe wall.

3. The Liner Is Inflated and Then Removed 

After inflating the liner, it will be removed from inside the existing pipe so that it can be installed in its new location. This can be done by pushing it through another section of the existing pipe or pulling it out through an access point like an open manhole cover or clean out port at each end of the replacement section

4. Final Assessment 

The final assessment is done with a video camera. The video camera allows our inspectors to see if there are any leaks or other problems with your pipes after they are repaired by trenchless technology

Sliplining is a trenchless method of pipe replacement that uses mechanical force to push the pipe through the existing pipe. The new pipeline is installed in a continuous line below ground level. The old pipeline is cut into sections and pulled out of the ground

Fold and Form Method 

The foldandform method uses a special tool to bend a section of new pipe around an existing section so that it forms a tight seal with no need for additional adhesives or fasteners. This 

method is often used when there isn’t enough room in front of or behind an existing section of pipe because it doesn’t require any excavation or other preparation work before installation.
