Quick, low-risk steps

  1. Stop using fixtures if you suspect a sewer problem.
  2. Keep people and pets away from any excavation or sewage.
  3. Ask for the complete camera inspection recording and defect location.
  4. Confirm who owns the affected pipe section (public vs. private).
  5. Compare pipe work and surface restoration as one scope of work.

How Pipe Bursting Works

Pipe bursting is a trenchless method that replaces an existing buried pipe without fully excavating it. A bursting head is pulled through the old pipe, fracturing it outward while a new pipe is pulled in behind. This technique can be used for various pipe materials, but the existing pipe must be able to fracture and the surrounding soil must accommodate the expansion.

The process requires two access pits: one at the starting point and one at the ending point of the run. The new pipe is typically high-density polyethylene (HDPE) that is fused together above ground and then pulled through. Because the new pipe is continuous, it eliminates joints that could become weak points.

  • Requires access pits at each end of the pipe run.
  • New pipe is pulled through as the old pipe is burst apart.
  • Works best with fracturable pipes like clay, concrete, or cast iron.
  • HDPE is a common material for the new pipe due to its flexibility and joint-free construction.
  • The bursting head can be expanded to upsize the pipe diameter.

Utility Conflicts and Locating

Before any excavation, a utility locate is required. Call 811 to have underground utilities marked. This is a free service, but it only marks public utility lines. Private lines, such as those for a detached garage or landscape lighting, may need a private locator. The presence of other utilities close to the sewer line can make pipe bursting risky or impossible.

If gas, electric, or water lines cross or run parallel to the sewer line, the bursting process could damage them. A professional plumber or sewer contractor will review the utility marks and the camera inspection to determine if pipe bursting is safe. In some cases, spot repairs or a different method may be needed to avoid utility conflicts.

  • Call 811 before any digging to mark public utilities.
  • Private utilities may require a separate locate service.
  • Nearby gas, electric, or water lines can be damaged during bursting.
  • A camera inspection helps identify potential conflicts.
  • The contractor should have a plan for crossing or parallel utilities.

Surface Restoration and Landscaping

Pipe bursting minimizes surface disturbance compared to traditional excavation, but it is not damage-free. The access pits will require excavation, and the bursting process can cause ground movement that may affect landscaping, hardscaping, or structures above the pipe. The contractor should explain what surface restoration is included in the quote.

After the new pipe is installed, the access pits are backfilled and the surface is restored. This may include replacing sod, reseeding, repairing pavement, or resetting pavers. It is important to compare quotes with the same scope of surface restoration to avoid unexpected costs. Ask if the contractor will handle all restoration or if you will need to hire a separate landscaper or concrete contractor.

  • Access pits require excavation and later backfilling.
  • Ground movement can affect landscaping, driveways, or patios.
  • Confirm what surface restoration is included in the quote.
  • Restoration may involve sod, seed, concrete, or pavers.
  • Compare quotes with identical surface restoration scopes.

Limitations and When It May Not Work

Pipe bursting is not suitable for every situation. If the old pipe is collapsed, has significant sags, or is surrounded by unstable soil, the bursting head may get stuck or the new pipe may not align properly. Additionally, if the pipe is too shallow or too deep, the method may not be feasible. A professional assessment is needed to evaluate these conditions.

Other limitations include the presence of multiple bends or connections that cannot be accommodated by the bursting process. In some cases, a hybrid approach with some excavation may be necessary. Always ask the contractor to explain why pipe bursting is or is not recommended for your specific situation based on the camera inspection and site evaluation.

  • Collapsed or severely sagging pipes may prevent bursting.
  • Unstable soil can cause misalignment or failure.
  • Multiple bends or connections may require excavation.
  • Pipe depth and diameter changes affect feasibility.
  • A professional camera inspection is essential to assess candidacy.

Common questions

What homeowners ask next

Will pipe bursting damage my landscaping?

It can cause some ground movement and requires access pits, so landscaping may be disturbed. The contractor should explain what surface restoration is included.

Do I need a permit for pipe bursting in Chicago?

Yes, sewer line replacement typically requires a permit from the City of Chicago Department of Buildings. Your contractor should obtain the permit and schedule inspections.

Can pipe bursting be used if there are other utilities nearby?

It depends on the location and type of utilities. A utility locate and camera inspection will help determine if it is safe. In some cases, it may not be possible.
