Facts About Pipe Bursting And Pull-In-Place Sewer Lines

Pipe bursting and pull-in-place pipe installation are two techniques used in trenchless pipe repair. If your underground sewer pipes are deteriorated or fractured, these methods may be employed to fix the problem. Here’s more information about pipe bursting and pull-in-place pipe replacement.

Trenchless Repair Eliminates Site Disruption

To repair root infestation, deterioration, and cracks in plumbing lines, plumbers must be able to see the problem pipes. However, it’s not possible to see buried water, sewer, or drainage lines without some help.

In the past, sewer pipes had to be uncovered by digging up the soil over the lines to expose the pipes, Since pipes can run underneath sidewalks, driveways, and fences, digging out pipelines can create a huge disruption to homeowners.

Trenchless plumbing techniques allow plumbers to repair buried lines without digging up all of the ground on top of the pipes. Trenchless methods like pipe bursting and pull-in-place pipe installation help homeowners avoid expensive repairs to their properties that would occur after conventional digging.

In a trenchless repair scenario, instead of moving dirt around your yard, your plumbing professional uses tools that travel inside the buried pipes. Cameras can be inserted inside pipes to see precisely where damage and clogs have stopped up the lines. Repairs are completed with minimal digging and site disruption.

Pipe-Bursting Methods Vary

To begin the process of breaking up and expanding your old pipes, plumbers set up a staging area. After the equipment is ready, the pipe-bursting hose is fed into your pipes. The hose pushes a cone-shaped, pipe-bursting head through the damaged line.

The point of the cone is aimed into the pipe, while the wide end of the cone helps break up the existing pipe as the pipe-bursting head moves through the line. A pulling cable or rod may also be attached to the head to help guide the apparatus.

Compressed air may be introduced into the line to blow out debris and help expand the diameter of the pipe as the head is pulled through the line. Pull-in-place or another type of pipe can then be installed to replace the removed pipe.

Pipe-bursting techniques include the following types:

  • Pneumatic
  • Hydraulic
  • Static
  • Pipe-splitting
  • Pipe-reaming

Your plumber chooses the pipe-bursting method that works best for your situation. Factors considered when choosing a pipe-bursting method include your existing pipe material, soil type, and equipment available to the plumber.

Pull-In-Place Pipes Follow the Bursting Head

If you have pull-in-place sewer lines installed with your pipe-bursting service, the new lines are pulled through the pipes directly behind the pipe-bursting mechanism. The newly expanded lines can now accept pipes that are over 100 percent larger in diameter than the old pipe.

If the replacement pipes are cure-in-place pipes (CIPP), the flexible piping may be fed into the lines inside-out and then unrolled to become right-side-out inside the line. Other CIPP piping enters the expanded lines with the right side already out and is pulled directly into place. Lines are expanded with air or water and cured after they’re in place.

CIPP is created by impregnating resin into sleeves made of felt or other fiber. These types of pull-in-place pipes offer a 50-year lifespan once they’re properly cured. The CIPP material is strong enough to withstand soil, water, and road compression.

Sewer lines are inspected after the installation of CIPP to ensure that the pipes are fully expanded, cured, and free-flowing. Your plumbing service can often complete your necessary sewer repairs in a few hours using trenchless technology.
