WHAT IS VACUUM EXCAVATION?

Vacuum excavation is a safer, more environmentally friendly and cost efficient method of excavating.

A vacuum excavator is a construction vehicle that removes heavy debris and material from a hole in the ground in urban and suburban areas. Fast excavation is guaranteed without the risk of affecting or damaging any unforeseen utilities.

WHERE CAN IT BE USED?

  • Tunnel building
  • Installing trenches & pipeline
  • Install new utilities & work around old ones below ground
  • Waste transfer & disposal
  • Building renovation
  • Tree root renovation
  • Emergency services
  • Disasters

EXCAVATION COMPARISON

Vacuum excavation virtually eliminates the risk of damaging underground utilities, while mechanical digging with hand tools or backhoes could potentially damage to those utilities.

Vacuum excavation is much less invasive than traditional methods of hand-digging. It also offers lower cost with a higher level of precision with less surface restoration needed afterwards.

The table on the right demonstrates how much material can be excavated on a daily basis using the manual hand-dig method compared to vacuum excavation and ultimately what the average cost incurred is per cubic metre.


COMPLETE JOBS FASTER

Vacuum excavation is much faster than other excavation methods especially manual digging and?can be essential for reducing disruption to homes, businesses and services, especially within urban areas.

The amount of material removed during the excavation of a site can depend largely on the material being excavated. Whether it’s sandy soil or much heavier soil with buried pipes or cables it’s still the preferred choice and much faster than traditional manual methods. See the chart for a comparison of how much material can be removed within 6 hours.

HOW DOES VACUUM EXCAVATION WORK?

Vacuum excavation firstly uses a high power blast of air directed into the site in order to loosen soil and break up any large materials. An air vacuum hose is then passed into the site and used to suck up the loosened materials out of the hole and into a specially designed tank, ready to be transported elsewhere or saved for refilling the site later.

 

WHY CHOOSE VACUUM EXCAVATION?

  • Manual/traditional excavation methods are more prone to strikes
  • Hand tools account for greatest number of utility strikes – despite pre-excavation scans
  • In 2017 contractor fined ?600k when subcontractor hit electrical cable & was injured
  • Approx 4 million excavations every year to install or repair buried utility pipes and cables
  • Average utility strike costs ?30k but can run into millions
  • Approx. 12 deaths and 600 serious injuries annually from contact with electricity cables

AVOID CABLE STRIKES

Incidences of electrical cable strikes has risen 668% in five years.

The number of ‘safety related electrical incidents’ caused by underground cable, joint or link box damage reported under the requirements of the Electricity, Safety, Quality and Continuity Regulations 2002 to the HSE.

THE BENEFITS OF
VACUUM EXCAVATION

VACUUM EXCAVATION IS SAFER

  • Maximises operative safety by minimising manual handling
  • Extension tube made from p.e. pipe to reduce utility damage
  • Extension tube insulates vehicle and workforce when working in high risk areas
  • Hydraulic power arms to increase manoeuvrability & reduce manual handling
  • Over 60% reduction of utility damage compared to traditional methods

VACUUM EXCAVATION INCREASES PRODUCTIVITY

  • Superior efficiency to manual work
  • Reduces staff workload
  • Easy to collect and remove solid and liquid substances
  • Greatly reduces construction time
  • Ready to operate immediately

VACUUM EXCAVATION IS MORE EFFICIENT & LESS DISRUPTIVE

  • Excavate in a third less space than a mini-digger
  • Cleaner more compact sites, therefore less disruption and waste
  • Stand-alone machine operation
  • Combine with soil engineering equipment impact moles keyhole liquid soil
  • Multiple uses
