Trenchless technology saves time, money and the structural integrity of existing infrastructure. It allows for the construction of new underground facilities, without the dangers that can come with an open trench, reduces the need for road closures, and has significantly less environmental impacts than traditional excavation methods. Difficult terrains like waterways or mountain ranges, which have restricted passage access for underground utilities like water and gas, can be quickly bored under.
In dense urban areas, where customer impact is imminent, many utility providers require that directional drilling be utilized to preemptively mitigate public outreach issues, including parking interference, noise pollution, dust creation and traffic delays. Delicate environmental landscapes like coastal estuaries and rivers can be preserved by safely boring under them by hundreds of feet deep, leaving the surface completely undisturbed.
Auger boring is traditionally utilized at shallow depths, under fragile structures like railroad tracks and concrete highways. Eastern Utilities Services’ auger bore machines directly insert a steel casing under the desired location, while maintaining its exact pitch and grade. They remove the existing soil to the exact diameter of the new pipe, without hammering or ramming, virtually eliminating the danger of "humps" or future ground settlement. Many civil engineers exclusively specify that this style of pipe construction is used in their designs.
Pipe bursting is a trenchless technology that allows an existing damaged pipe to be replaced with a pipe of equal or larger diameter by threading a cable through the old pipe, then hydraulically ramming a new pipe in place while ejecting the existing one. This is an ideal solution for upgrading an aging gravity sewer system without requiring digging or surface disruption.
