Vacuum Excavation: Everything There Is To Know


You’ve probably seen a vacuum truck moving around the city before, as they routinely clean clogged drains. They, however, accomplish a great deal more.

Vacuum trucks are equipped with a unique collection of tools. A pressurized air lance, drain cleaners in brisbane, a waste storage chamber, and twin or triple air vehicle fans are also included. The ground is drilled and disseminated with the air spear throughout excavation work, and then dispersed into the truck’s waste chamber to be contained for disposal.

Vacuum excavation is used for excavating around cable or utility lines, pipelines, and, in some instances, rail lines for repair or removal because of its precision and accuracy. They can also be used to unclog municipal drains and other drainage systems, as previously noted.

On the other hand, if you’re still on the fence about how a vacuum excavation works and what is it all about, the following guide will explain everything.

How a vacuum excavation works

Vacuum excavation is a two-step process that involves breaking up soil and underground debris using pressured air and then sucking it up to clear the area.

Although the high-pressure air is robust, it poses little threat to buried utilities wires or pipes. That’s how the term “soft dig” came to be. This procedure is extremely efficient, requiring the least amount of soil disturbance to uncover the utilities and clear the work area. Operate crews may work more effectively once the vacuum pipe has slurped up the debris and dirt into the reservoir and out of the way.

The types of vacuum excavation

Jet rodders, sucker trailers, and vacuum trucks are the three main types of vacuum excavation.

  • Jet rodding entails the use of a precision hose that blasts high-pressure water into the ground, slush, and even tree roots, breaking up the dirt, slush, and even tree roots.
  • Vacuum excavation trucks collect rubbish (typically formed by jet rodding) and deposit it in a big tank, exposing the excavation area with minimal environmental impact.
  • Sucker trailers are custom-built trailers that function similarly to suction trucks but in a trailer configuration.

Vacuum trucks are useful for a wide range of activities, and their design makes them a great “portable” garbage and construction solution.

Benefits of vacuum excavation

The key advantage of employing a vacuum excavation truck is that it causes the least amount of damage to existing and subsurface piping, electricity, cabling and other lines. Because the work done by a vacuum excavator is more exact and accurate, less backfilling is required. Vacuum excavation is more advanced than traditional digging methods and is far safer due to the process’s greater control. The suction mechanisms dig the materials but keep them within the storage unit, resulting in a cleaner workspace.

Projects requiring vacuum excavation

Is vacuum excavation a viable option for every underground project? Yes. It’s typically used for the following applications:

Debris removal from the building site,

Locating and measuring underground utilities is a difficult task.

Valve boxes and catch basins must be cleaned.

Repairs of sewer lines

Excavation beneath a standing structure, often known as remote excavation,
