Vacuum Excavation

Safedigging can now offer a number of specialist services and products ranging from our Vac Truck, Suction/Vacuum excavation service, through to our new RN-1 Remote Nozzle safe distance excavation service. The vacuum excavation division is a specialist service designed to complement our existing services and increase the accuracy and level of confidence in the underground surveying and identification of underground utilities PAS128 - Survey Type A, Verification.

The Suction/Vacuum Excavation service introduced by Safedigging Ltd, offers huge improvements in operator safety and cable strike avoidance to any company facing difficult excavations where there may be buried services or where a PAS128 Survey Type A (Verification) is required.

The introduction of the RN-1 remote nozzle allows suction technology to be applied to new areas of operation such as culverts, small tunnels, storage tanks etc. and can remove the need to place operatives in these confined space areas, representing another advance in site safety.

Vacuum Excavation is the only safe-dig option recommended by Safedigging for Verification and Confirmation of located underground utilities.

What is Vacuum Excavation?

Vacuum / Suction Excavation has been operating within mainland Europe in excess of ten years in one form or another, but it is relatively new to the UK.

This vacuum, or suction excavation system as it is sometimes referred to operate under various names such as Vac-Ex, Vacuum-Ex, Suc-Ex, as well as Hydro Vac, and Aqua Vac (both combining water jetting) but in all cases, the principals of this excavation method remain the same.

Vacuum excavation in simple terms allows the use of a vacuum excavator, also referred to as a vacuum tanker or vacuum lorry, to operate and excavate material around buried services or utilities including gas, electric, water, telecoms and fibre-optics by removing the soil, earth or other material covering the services by means of high volume air flow.

Vacuum Excavation, or Suction Excavation as we have mentioned it may be referred to, avoids the requirement for invasive digging methods such as hand digging or the use of traditional mechanical excavators, thereby virtually eliminating possible cable or service damage

Over the previous two years vacuum/suction excavator vehicles have made a significant appearance in the UK with an ever increasing number of companies utilising this technology to help reduce service strikes and also avoiding possible injury to site operatives.

How does Vacuum Excavation work?

The process is simple - A Vacuum Excavator, also sometimes known as a Vacuum Tanker or Vacuum Lorry (see diagram on right) generates a high volume flow of air by means of its twin or triple air fans

Air flows through the machines intake nozzle and hose into a series of chambers, including the main material storage tank, before passing through a micro mesh filter system and then out into the atmosphere.

When an operator directs the machines intake nozzle at the ground to be excavated, the air flow vacuums the ground material into the vacuum excavator and this material is deposited into the main storage tank.

Small soil particles drop into a further two smaller tanks and any dust particles are caught in the micro mesh filter system before the air finally passes from the machine.

Over the previous two years vacuum/suction excavator vehicles have made a significant appearance in the UK with an ever increasing number of companies utilising this technology to help reduce service strikes and also avoiding possible injury to site operatives.

If the ground conditions prove to be more challenging, the trained operator will then use an air lance or other air tools that are connected to the vacuum/suction excavator. These tools will assist in breaking the ground free. This will then allow the air flow to catch the material and then remove it into the vacuum excavator

This new safer approach to excavation projects is not intended to replace traditional or hand dig methods. There will always be operations where these approaches will need to be applied, however where there are services that could be damaged, or if there is uncertainty in the exact location of services, then vacuum/suction excavation is the way forward.

Additional Services:

Bag Pack System

Allows our suction vehicle to tip material into a special dual hopper system and then into suitable heavy duty weight certified (as per our clients requirements) storage bags. Ideal if material has to be reused on site.

This is a unique service offered by Safedigging Ltd.

The "Super Tip Skip" System

This can be used in a number of ways, either as a high sealable skip for our suction vehicles to tip material into, and when full, can be hydraulically sealed and removed from site.

Or, this specially designed skip can act as a sealed suction slave containment unit. Material can be drawn directly into this unit via attached intake hoses using the suction power from one of our main vehicles. When full this skip/container can be removed from site.

Ideal if dealing with contaminated materials.
