Vacuum excavators are used to remove unwanted material away from an area, including water from pools and dirt or mud surrounding utility assets. Vacuum excavation trucks (which are also known as sucker trucks, suction excavators or vac trucks) are primarily used to safely excavate around cable networks and buried pipelines, for emergency repair for utility and pipeline networks, for rail track maintenance deep excavation, confined spaces, sewer clearance, clearing around tree roots, basement work and more. They’re also commonly used for environmental maintenance, including clearing away any environmental damage and cleaning blocked gullies and gutters on the street.
Our directory offers a variety of qualified vacuum excavation services from suppliers throughout Australia. These suppliers offer a diverse range of vacuum excavation and non-destructive digging services to suit any project across the nation. Suppliers at iSeekplant offer a variety of services on top of just the standard vacuum excavation task, including radar utility location and soil transfer.
Vacuum excavation covers a range of activities with the most common centered around digging and collecting dirt around a utility or cable, without using traditional digging tools or machines. This process has become popular in recent decades as it alleviates the risks commonly associated with conventional digging via excavator and shovel. Using non-destructive digging techniques like vacuum excavation and hydro excavation has proven to significantly mitigate the risk of line strikes and utility damage, while also decreasing project time, across the world.
In layman terms, vacuum excavation is an excavation technique that uses a combination of air suction, compressed air lances, and high-pressured water jets to safely expose underground utility cable networks, buried pipelines, and even dated railways tracks for emergency repair, removal, and inspection.
Vacuum excavators use twin or triple air vehicle fans to create air flow, where a vacuum then pulls material inside the intake hose, where it’s transported into the catchment chamber. Sometimes the end of the tube will be toothed which helps to cut into the earth when it’s being used for excavating. From there, the material is sent to the holding tank, while a micro-mesh filter system captures all dust particles.
In action, you’ll typically find a vacuum truck parked closed to the task at hand, typically a location that needs to be dug up to access damaged or redundant utility cables, with the operator utilising a powerful water jet to break up the ground while the suction tube sucks up the dispersed waste, leaving the utility exposed.
