If your home's sewer line is reaching the end of its lifespan, pipe bursting could be a viable option for replacing it. This method is among the many trenchless technologies that are considered to be a more efficient and less intrusive approach to addressing compromised underground piping systems. Read on as New England Pipe Restoration explores a few essential things about trenchless pipe replacement and when it's an ideal solution for your home.
How Pipe Bursting Works
At its core, pipe bursting is a trenchless method of replacing or upsizing damaged sewer lines. The process begins with contractors digging two access points at opposite ends of the existing pipeline. A bursting head is then inserted into one of these access points and guided through the line by a hydraulic pulling machine. As it moves forward, it breaks apart the old pipe and pushes it into the surrounding soil, making room for a new pipe to take its place. The new pipeline, typically made of durable material like high-density polyethylene (HDPE), is pulled in behind the bursting head.
Equipment Used
Already mentioned above are two main pieces of equipment required for trenchless sewer replacement. The bursting head (also known as an expander or cone) comes in various sizes to fit different pipe diameters. It has a conical shape with sharp edges that fracture the old pipe as it moves through. Meanwhile, the hydraulic pulling machine is used to control the speed and direction of the bursting head, as well as provide the necessary force to pull in the new pipeline.
Other equipment used in this process includes winches, rods, and cables to guide the bursting head through the line. A video camera may also be utilized for inspecting the condition of the new pipe and ensuring proper installation.
Advantages of Trenchless Pipe Bursting
One of the primary advantages of trenchless sewer repair is its minimal ground disturbance. Since this technique does not involve digging extensive trenches, it reduces the impact on the landscape and existing infrastructure, such as roads and buildings. Additionally, it can be completed in a shorter time frame compared to traditional methods, resulting in significant cost savings.
Considerations for Implementation
Pipe bursting is often recommended for pipelines that are severely damaged or have completely failed—issues that will not be fixed by trenchless pipe lining. It is also suitable for upsizing existing pipes to accommodate increased water flow demand.
However, it may not be the best option in certain situations, such as when there are multiple bends or turns in the pipeline, if there are utility lines that are too close to the existing pipe, or if the soil conditions are less than ideal for the bursting process. It's crucial to consult with a certified technician to determine the right solution for your specific needs.
