Pipe Bursting Technology

Revolutionary trenchless method for replacing underground infrastructure without the disruption and expense of traditional excavation

Understanding Pipe Bursting Technology

Pipe bursting equipment and process

What is Pipe Bursting?

Pipe bursting is an advanced trenchless method for replacing underground sewer and water pipes. Instead of digging long trenches, the process requires only two small access pits at the pipe's ends. A specialized bursting head is pulled through the old pipe, breaking it into small pieces and pushing them into the surrounding soil, while simultaneously pulling a new HDPE pipe behind it.

The process uses five key pieces of equipment: an expander head with a leading end smaller than the trailing end, pulling rods, a pulling machine, a retaining device, and a hydraulic power pack. The expander head (also known as a 'bursting head' or 'bullet') is pulled through the old pipe, fracturing it as it moves forward while the new pipe attached to its back is dragged into place.

This innovative process involves breaking and expanding the existing buried sewer line while simultaneously replacing it with new high-density polyethylene (HDPE) pipes. The replacement pipe is one long fully fused polyethylene pipe with no joints, drastically reducing leak possibilities compared to traditional pipe segments with gasketed connections.

Traditional Challenges

Traditional pipe replacement requires extensive excavation, creating trenches along the entire pipe length. This causes:

  • Significant surface disruption to roads, landscapes, and buildings
  • High restoration costs for damaged surfaces
  • Extended project timelines
  • Environmental impact from excavation
  • Traffic disruptions and access issues

Our Solution

Pipe bursting provides utility owners the option of keeping the new pipe the same size as the original or increasing it by one to two pipe sizes, improving system capacity while minimizing disruption.

  • Minimal excavation required
  • Reduced labor hours
  • Lower repair and restoration expenses
  • Capacity expansion possible

When is Pipe Bursting Appropriate?

Deteriorated Pipes

Existing pipes are deteriorated but still maintain their general alignment

Capacity Increase

Need to expand pipeline carrying capacity by replacing smaller pipes with larger ones

Surface Preservation

Critical for areas like wetlands, roads, or residential neighborhoods

Fracturable Materials

Works with clay, concrete, cast iron, and other brittle materials

Straight Pipe Runs

Ideal for straight pipe runs between access points

Stable Ground

Ground conditions are stable enough to support the bursting process

Advantages Over Traditional Methods

Minimal Disruption

Unlike traditional excavation that tears up yards and hardscaping, pipe bursting only requires small access points

Time Efficiency

Skip the week of excavation equipment at your home, piles of dirt, and subcontractor haggling

Cost Savings

Factor in the potential of repairs to landscaping, walkways, and driveways - significant savings

Environmental Benefits

No added chemicals or contaminants - considered a very sustainable replacement method

Long-Term Reliability

Unlike traditional 20-foot pipe segments connected with gasketed ends which can leak over time, fused joints are just as strong as the pipe itself, drastically reducing leak possibilities. The replacement pipe consists of one long fully fused polyethylene pipe with no joints.
