All the Essential Details About Trenchless Pipe Bursting

Trenchless pipe bursting is an innovative and efficient method for replacing or rehabilitating underground pipelines without requiring extensive excavation. This technique is particularly valuable for minimizing disruption to the surrounding environment, reducing costs, and expediting the pipe replacement process. Nu Flow South Pacific is among Hawaii’s leading trenchless pipe repair service providers.

Here’s a quick overview of trenchless pipe bursting basics.

Process Overview

This particular trenchless pipe replacement method involves replacing an existing pipeline by fracturing the old pipe and installing a new one. The process is typically carried out as follows:

Locating or Creating Access Points

Two access points or pits are excavated, one at the entry point and another at the exit point of the pipeline segment to be replaced. This is a standard step that we carry out during trenchless sewer repair in Kailua-Kona, HI.

Bursting Head

A specialized bursting head is attached to the new pipeline. This head has cutting blades or a conical shape that helps break apart the old pipe as it advances. The bursting head is inserted into the old pipe from the entry point. As it travels through the pipe, it fractures the existing pipe and pushes the fragments into the surrounding soil. Simultaneously, the new pipe is pulled behind the bursting head and installed.

Trenchless sewer replacement via pipe bursting offers several advantages.

Minimal Disruption

The process requires minimal excavation compared to traditional methods, reducing disruption to landscapes, roads, and structures.

Cost Savings

Trenchless sewer pipe bursting can be more cost-effective than traditional open-cut methods, requiring less labor, restoration, and equipment.

Speed

The process can be completed relatively quickly, minimizing downtime and inconveniences associated with extensive construction.

Eco-Friendliness

Damaged pipes that were replaced via pipe bursting do not end up in landfills. Instead, the affected pipes will just be pushed out into the surrounding soil.
