What Happens to the Old Pipe During Sewer Pipe Bursting?

Pipe bursting is a trenchless technique used to replace damaged or aging sewer lines without large-scale digging. One common question is what happens to the existing pipe once the process begins. RDH Plumbing, Sewer & Drain Specialist provides sewer repair in Teaneck, NJ, and uses this method to give homeowners and businesses a reliable upgrade with minimal disruption. Understanding what happens beneath the surface can help you know what to expect.

The Old Pipe is Broken Apart

During pipe bursting, a specialized tool is pulled through the existing line. As it moves forward, the tool fractures the old pipe into small fragments. These fragments are pressed outward into the surrounding soil. The process clears a pathway for the new pipe to follow while keeping ground disturbance to a minimum. The old material is not removed but displaced, meaning heavy excavation is not necessary.

The New Pipe Follows Behind

Attached to the back of the bursting head is a replacement pipe. As the tool advances, it pulls the new pipe into the channel left behind. This allows contractors to replace sewer line sections with durable materials such as high-density polyethylene (HDPE). The result is a long-lasting system that functions as a complete upgrade, independent of the broken remnants that remain in the soil.

Why This Method Works

Pipe bursting is effective because it uses the strength of modern equipment to fracture existing materials while simultaneously installing new piping. It is commonly chosen when traditional excavation would be too invasive or disruptive. It is also a preferred option when homeowners want sewer pipe line repair that lasts and minimizes property damage.

Monitoring the Process

Before and after bursting, contractors often carry out a sewer camera inspection. This allows technicians to confirm the old pipe’s condition, check alignment, and verify that the replacement has been installed correctly. Video inspection provides important documentation and helps assure homeowners that the process was completed successfully.

FAQs

Q: How long does a typical pipe bursting project take?

A: Most trenchless sewer line replacement projects can be completed in one to two days, depending on the length and depth of the line and site conditions.

Q: Is the new HDPE pipe stronger than the old one?

A: Yes, the new HDPE pipe is seamless and highly resistant to cracks, corrosion, and root intrusion. It is also more flexible, which makes it less susceptible to shifting soil or ground movement. The lifespan of a new HDPE pipe can be 50 years or more.
