Pipebursting is a trenchless method used to replace old or damaged pipes without the need for extensive excavation. Here's how it works:

• Access Points | The process begins by creating two small access points, typically one at the beginning of the pipe and one at the end. These access points serve as entry and exit points for the new pipe.

• Bursting Head Insertion | A specialized tool called a bursting head is attached to a cable or hydraulic system. The bursting head is larger in diameter than the old pipe and has cutting blades or other mechanisms at the front.

• Guided Process | The bursting head is inserted into the old pipe from the entry point. As it progresses through the pipe, it breaks apart the old pipe using its cutting blades. At the same time, it pulls a new pipe of the desired material behind it, such as HDPE (high-density polyethylene) or PVC (polyvinyl chloride). The new pipe is of the same or larger diameter than the old pipe.

• Simultaneous Replacement | The bursting head fractures the old pipe and pushes the fragments into the surrounding soil. At the same time, the new pipe is pulled into place, essentially replacing the old pipe with the new one.

• Completion and Connections | Once the bursting process is completed, the access points are used to make necessary connections to the existing sewer or water system. The connections are sealed, and the new pipe is tested to ensure it is properly installed and functional.

Pipe bursting is advantageous because it avoids the need for open trenches, reducing the disruption to the surrounding area. It is commonly used to replace deteriorating or damaged pipes, especially in urban areas where excavation might be difficult or costly. Additionally, it allows for the installation of larger-diameter pipes, improving the overall capacity and efficiency of the drainage system.
