Vacuum Excavation (also known as Suction Excavation), is a safer and more efficient method of excavating around the underground live services by using high pressure air to loosen the soil and vacuuming it away.
The process significantly reduces the risk of underground cable strikes and injury to the workers associated with the utilities.
Vacuum excavation works by generating a high volume of air flow using twin or triple air fans. The operator directs the intake nozzle at the ground, causing the ground material to be sucked into the vacuum excavator and deposited into the main storage tank. Small soil particles are collected in two smaller tanks, and dust particles are filtered out by a micro mesh system before the air is released back into the atmosphere.
For challenging ground conditions, an air lance or other air tools can be used to break the ground. While vacuum excavation is not meant to replace traditional digging methods, it is ideal for situations where underground services might be damaged or their exact locations are uncertain.
By using advanced digging technology, we significantly minimize the risk of damaging underground utilities, ensuring the integrity of essential services remains intact.
Our state-of-the-art equipment allows for quicker and safer digging compared to traditional hand methods, boosting productivity and enhancing safety on-site.
With a strong focus on safety, our methods ensure excellent health and safety records, protecting both our workers and the environment from potential hazards.
Our efficient techniques significantly lower site costs by reducing time spent on projects and preventing damage that could lead to costly repairs, ensuring a smooth and economical operation.
By employing precise and innovative digging techniques, we significantly reduce the likelihood of accidental service strikes, ensuring uninterrupted utility services.
Our careful and compliant digging practices help in minimizing legal liabilities and environmental impacts, promoting sustainable and responsible operations.
Underground utilities are observed and located in an inspection survey or manhole chamber or excavated and exposed.
