How Does Pipe Bursting Work?

Pipe bursting is gaining popularity, and its demand is expected to rise in the following years due to its numerous advantages, such as its low-cost and ecological friendliness as an alternative that causes minimal interruption to the surrounding area. This method is used when you cannot fix the broken pipeline with either the traditional digging or trenchless sewer methods.
Keep reading to understand how pipe bursting works and the benefits it offers.

What is Pipe Bursting?

Pipe bursting is a trenchless method of replacing existing pipelines with new ones. It involves breaking apart the existing pipe and pushing the fragments into the surrounding soil while simultaneously pulling a new pipe into place. The process is completed without extensive excavation, making it a much more cost-effective and efficient solution than traditional pipe replacement methods.

This method is typically used when the water and sewage pipes below the ground are severely damaged beyond repair due to age, rust, tree roots, or other obstructions. Occasionally, we must replace pipes to prevent possibly dangerous lead pipes that can discharge harmful substances into water supplies.

How Does Pipe Bursting Work?

Pipe bursting involves a series of steps carefully planned and executed by trained professionals. Here is a breakdown of the process:

Step 1: Access Points

The first step in pipe bursting is to create access points for the existing pipe. This is typically done by digging a small pit at each end of the pipe section that needs replacing. These pits will be used to insert and extract the bursting equipment and new pipe.

Step 2: Inserting Bursting Head

The bursting head is a specialized piece of equipment designed to break apart the old pipe and create a path for the new pipe to be pulled into place. The bursting head is attached to a cable fed through the pipe and out the other end.

Step 3: Pipe Bursting and New Pipe Installation

The bursting head, powered by hydraulic pressure or compressed air, forces it through the existing pipe. As the bursting head moves through the pipe, it breaks the old pipe apart and pushes the fragments into the surrounding soil.

Simultaneously, a new pipe is pulled into place behind the bursting head. The new pipe is attached to the cable and fed through the old pipe, allowing it to be pulled into place. The size and material of the new pipe will depend on the project’s specific needs.

Once the new pipe is in place, the bursting head is removed, and the new pipe is connected to the existing system. The access points are then filled, and the site is restored to its original condition.

How Much Does Pipe Bursting Cost?

The cost of pipe bursting can vary depending on several factors, like the pipeline’s length, the type of pipe being replaced, accessibility, depth, the condition of the surrounding soil, and the pipeline’s location. The cost can also vary based on the contractor you choose and the area in which you live.
