What is Pipe Bursting?

Utility lines are typically buried underground, and thus cannot be readily accessed in the event of damage. Water and sewer lines in particular have a limited lifespan, which is dependent on their material. When these lines fail, the lives of residents can be greatly affected. Pipe bursting is one of the few methods of replacing failing water and sewer lines.

The process requires accessing the two ends of the pipe - usually one inside the building, the other at either the main or the property line. Rods are used to pull a cutter through the existing pipe, bursting it apart. The new pipe is then fed through the tunnel left from the old pipe.

Why perform renewals?

Water and sewer infrastructure is vital to our modern day life. A water line failure can lead to decreased water pressure and accumulation of groundwater. Both issues can result in further complications, such as the loss of running water, leaks into basements, sinkholes in the lawn, corrosion on the footings, and foundation cracks. Sewer failures can be far more immediate drastic: clogs and collapses can quickly manifest as a backing up sewer, which may lead to sewage back-charging into the basement. This will soak and penetrate drywall, framing, furniture, flooring and other items, generating thousands of dollars property damage if not addressed promptly. Additionally, many insurance companies do not cover water damage.

When it comes to evaluating your utility lines, it is best to know what material your line is. The different materials and their characteristics are as follows.

Sewer:

  • NoCoRode (NCR): Tar Paper. Initially chosen for its cheap pricing, over time the material will start to blister, and eventually collapse. Blisters cause hills and valleys inside the pipe, narrowing the flow. The material is vulnerable to root intrusion, and to cuts and breaks during rooter cleaning. It is no longer available due to its numerous problems.
  • Clay Tile: Pipe made from treated clay. Relatively steady, however joints are not secure, and ground movement may result in misalignment. Damage/cracking quickly leads to collapse, blocking sewage flow. Prone to root intrusion.
  • ABS Schedule-40: A thinner variant of ABS. Prone to warping, forming swags and ovals.

  • ABS: Heavy plastic similar to PVC. Resistant to deterioration and root intrusion. Takes many years to experience warping. Material of choice for Groundhoggers Coring Inc.
Water:
  • Poly B: a plastic polymer. Chosen for its cheap pricing. Typically flexible, but may grow brittle over time. Oxygen permeable, which may allow oxidized water into water heaters, which shorten the lifespan of the heaters.
  • Copper: a metal pipe. Common for interior piping. Generally keeps from rusting.

  • Municipex: a plastic polymer. Flexible, yet sturdy due to comparatively thick walls. Material of choice for Groundhoggers Coring Inc.

Why go trenchless?

Beyond pipe-bursting, the other available options are pipe relining and open trenching. Pipe relining is a temporary measure, only providing repairs instead of treating the root cause of old/damaged infrastructure. Open trenching provides full access to the pipe, allowing for local treatment, and visible placements. However, open trenching can occur many extra costs, both in money and time.

Excavation costs immediately increase. While pipe bursting only requires digging out the set-in and/or catch hole, trenching requires digging along the entire line (manageable in short runs, but increases with distance). Additionally, tree roots and utility lines may cross over the line several times, leading to the need to hydro-vac or hand dig in areas. In some instances, trenching may require removal of the tree.

Following replacement of the pipe, recovery costs come into play. Property lines are generally set so that the municipality is responsible for relaying road asphalt and sidewalk concrete. Anything inside the property line is the responsibility of the landowners. This means trenching will lead to costs incurred in replacing concrete for a driveway, replacing grass for a lawn, or any other landscaping costs. Pipe-bursting limits these costs to the area of set-in and catch holes.
