In trenchless sewer repair, pipe bursting involves breaking and expanding the existing buried sewer lines while simultaneously replacing them with new high-density polyethylene (HDPE) pipes.

The process of pipe bursting does not require the use of chemicals or other contaminants. Due to the long lifespan of the environmentally-friendly HDPE pipe, pipe bursting is considered to be a very sustainable sewer replacement method.

How is a pipe bursting sewer line replaced?

Bursting pipes is accomplished by pulling an expander head (also known as a “bursting head” or “bullet”) through the old pipe. It is small enough to fit through the existing pipe, and as it is pulled through, it breaks the existing pipe.

A new pipe is connected to the back of the head, which it drags behind it.

Power must be applied to the device using a pulling machine. In most cases, power is drawn from a hydraulic power pack, and it is applied to pulling rods attached to the expander head. As the pulling machine is positioned in the receiving pit, the head starts its journey in the launching or insertion pit.

How Much Does Pipe Bursting Cost?

The cost for trenchless sewer replacement services will depend on your situation. The main cost factors may include:

  • The depth of the existing pipe
  • The length of the pipe
  • The amount of damage
  • Where the sewer lateral is located on the property
  • Nearby structures built into the foundation of the property (such as garages, sheds, in-law units)
  • The number of other underground utilities nearby the line
  • The number of branch connections
  • Number of off-set joints or sinkholes
  • The slope of the pipe (and whether it needs to be adjusted)
  • If the neighboring property is connected to your line
  • The type of materials needed for your project
  • Traffic control, parking permits and other factors to do with working in the public right of way
  • The surface restoration factors (such as higher end flagstone, tiles, and plush gardens with complex irrigation systems)

You can estimate pipe bursting costs by multiplying the number of feet of pipe by the going rate, which ranges from $60 to $200 per foot. Depending on your situation, you might pay anywhere between $4,500 and $20,000.
