What is pipe bursting?
Pipe bursting is a well-established trenchless method that is widely used for the replacement of existing and deteriorated pipe with a new pipe of same or larger diameter. Many factors should be reviewed thoroughly before double upsize or greater projects are considered and released for bid. Engineers should consider different options, and select the most cost-effective and environmentally-friendly methods for bid. The method selection should not be left to the judgment of the Contractor only.
Pipe bursting is especially cost effective if the existing pipe is out of capacity. This method can be used advantageously to reduce damage to pavements and disruptions to traffic, hence reducing the social costs associated with pipeline installations. There are, however, limits to the use of pipe bursting method and various conditions provide a challenge to the successful use of its application.
