The most experienced Suction Excavation specialists in the UK
Instant operability and fast excavation without the risk of affecting or damaging any unforeseen utilities.
Suction excavation Technology has been specifically designed for specialist construction activities in urban and suburban areas. It assures instant operability and fast excavation without the risk of affecting or damaging any unforeseen utilities. Use of suction excavation also reduces environmental impact by overcoming possible damage to tree roots, as the suction excavator clears past these without damage.
Conroy Group was the very first to bring Suction Excavators into the UK in 2006. We have a large fleet, backed up by a wealth of experience in the industry.
Applications for Suction Excavation
The suction excavator works in a similar way to a cyclonic cleaner, but with immense suction power. The high negative pressure air current removes all materials through a suction nozzle using a flexible arm attachment fixed to the back of the excavator vehicle.
The spoil collected is deposited in a self-contained unit mounted on the suction excavator vehicle. When the container reaches capacity, the lid is hydraulically opened, and the entire chamber is mechanically tipped over and the contents discharged into a low-level skip. The spoil is then removed from site and taken to either a landfill or ideally, a recycling facility.
Operating suction excavation capacities of around 45m3 per day are commonly achieved here in the UK (figure based on 26 metric tonne unit with a 7m3 container). The suction excavator is ideally suited for use in uncovering defective underground pipes and cables, which are too dangerous to expose using standard open cut procedures. It has received recognition for brand value innovation from the likes of BP & Shell.
Why use Suction Excavation?
- Excavations size is greatly reduced, leading to lesser environmental impact and a reduction in excavated material. This means less material for landfill.
- Waste can be managed through operation of suction excavator allowing separation of hazardous and non-hazardous waste.
- Liquid Waste can be easily removed through excavator operation, allowing suitable prevention of any pollution to land/watercourses.
- Due to sealed suction system all dust is captured at source and transferred to excavator reducing the risk of nuisance to public and others.
- Noise Levels – of suction excavator are well below that of conventional plant and equipment associated with this type of work activity
- The risk of hand and arm vibration – is eliminated as the use of conventional plant and equipment for most of the work activity is eliminated.
- As all excavated material - is removed from excavation directly into suction excavator sealed unit, the risk of employees inhaling dust normally associated with excavation activity is eliminated.
- Utility Service Strikes are one of the greatest risks in carrying out any excavations, this is virtually eliminated by using vacuum excavation as recommended by the HSE.
- Slips, Trips and Fall injuries have been greatly reduced due to no excavated material being stored within the work area. All material excavated is immediately transported to suction excavator.
- Manual Handling Injuries all but eliminated due to operation not requiring manual excavation or plant and equipment to be moved to and from work area.
- Public Safety in greatly increased due to smaller excavations and the reduction of time spent on site, reduced plant and equipment on-site, elimination of excavated material within work area.
- Faster and more efficient excavation compared to traditional open cut methods.
- Increased operational safety
- Reduced excavation sizes and subsequent cost savings
- No mains or cable shutoffs required whilst excavating
- Approved for use on contaminated ground
- Approved for use when laying pipes and cables through infrastructure
