Pipe Bursting
Rescue Rod’s portfolio of trenchless rehabilitation services offers our municipal and industrial customers cost effective solutions to their underground asset management problems and providing clear advantages over more disruptive and environmentally damaging excavations.¡

  • Restoration of pipeline’s structural integrity.
  • Retention of sewer and pipeline capacity.
  • Improvement in lifetime of repaired sewer.
  • Costs often minimized by use of trenchless techniques.Horizontal drilling units ensure smooth running operations in a minimum amount of time.
  • This is a leading edge form of technology offers a variety of options designed to meet the needs of varying applications

  • The Piping Problem
    No matter where you go, water, sewer, gas and other utilities are in a constant state of deterioration or incapable of meeting the rising needs of urban areas where population growth is a problem. In most cases, water lines have become corroded to the point where they are wasting water and incapable of meeting water supply requirements. Most sewer lines are often cracked or corroded to the point that they cannot transport the waste material without stoppages and leaking into the environment. The biggest problem is that most of these pipelines are located in overcrowded cities, under buildings, roadways, rivers where replacement by traditional open-trench methods is not a plausible option.

  • A Piping Solution
    Pipe bursting represents the ideal pipe rehabilitation solution for replacing and upsizing the capacity of existing pipelines while avoiding the economic and social costs of traditional methods. Pipe bursting is the only trenchless process that enables a city to revitalize its piping system without extensive excavation and traffic stoppages.

The Pipe Bursting Process
Pipe bursting involves using a winch to pull a heavy duty polyethylene pipe through an old pipeline of equal or smaller size. The old pipeline is shattered using a high-powered tool with special bursting heads that smash through the old pipe while pulling through the new replacement pipe. When pulled into the old pipe, the bursting head breaks the pipe into pieces, enlarges the hole and pushes the fragments into the surrounding soil. This limits pipe bursting to pipes that can be fractured and to soil conditions that will absorb the old fragments. 

Pipe bursting has found new applications in the municipal area for replacement of water mains and gravity sewers. Recent advances in bursting head technology has produced three kinds of pipe bursting technology each of which uses a different bursting head: hydraulic, pneumatic or cone cracking. While the range of pipe size and length is constantly increasing, pipe rehabilitation projects have involved pipe diameters of 3" to as much as 30" and straight pulls of HDPE pipe as long as 1500 feet. As pipe bursting technology advances, different types of pipe material can be replaced. At the moment, pipe materials include vitrified clay pipe, asbestos cement pipe, truss pipe, reinforced and un-reinforced concrete pipe, and cast iron pipe.

Advantages of Pipe Bursting
As a "no-dig process", pipe bursting is the perfect solution for a municipality looking to increase the capacity of its water supply pipes or to replace corroded and leaking sewer pipes. All of this is possible without extensive excavation and all the other costs of surface restoration. Because its trenchless, pipe bursting is the preferred method for replacing old pipes in urban areas where disruption to surrounding utilities, local residences, businesses and the environment are a consideration. An added benefit of using HDPE plastic pipe for pipe bursting is its suitability for non-pressure applications like sewer lines. Because of its smooth inner walls, HDPE pipe assures high gravity flow rates and minimizes the chances of developing stoppages.
