Vacuum excavation is essentially the excavate material around buried services or utilities including gas, electric, water, telecoms and fibre-optics by removing the soil, earth or other material by means of high-volume air flow.

This avoids the need for invasive digging methods such the use of traditional mechanical excavators, thereby virtually eliminating possible cable or service damage.

It also offers huge improvements in operator safety and cable strike avoidance particularly for difficult excavations or where a PAS128 Survey Type A (Verification) is required.

The vacuum excavation is a specialist service designed to complement existing services and increase the accuracy and level of confidence in the surveying and identification of underground utilities.

How does Vacuum Excavation work?

The process is simple - A Vacuum Excavator generates a high volume flow of air by means of twin or triple air fans.

When an operator directs the machines intake nozzle at the ground to be excavated, ground material is sucked into the vacuum excavator and 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 back out into the atmosphere.

If the ground conditions prove to be more challenging an air lance or other air tools can be connected to assist in breaking the ground free. 

Vacuum excavation is not intended to replace traditional digging methods, 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.

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.

  • Reduce damage to underground utilities
  • Increase productivity and dig faster and safer than by hand
  • Maintain excellent health and safety records
  • Reduce site costs, in time and damage over conventional digging methods
  • Reduce service strikes
  • Reduce legal and environmental issues

Alongside the Vac Truck, Suction/Vacuum Excavation Service, Safedigging can also provide the following complementary services:

Confined Space Excavation: The RN-1 remote nozzle allows suction technology to be applied in confined spaces such as culverts, small tunnels & storage tanks etc.

Bag Pack System: Our suction vehicle can to tip material via a dual hopper system into suitable heavy duty, weight certified storage bags. Ideal if material must be reused on site.

The "Super Tip Skip" System: This can be used in several ways, either as a sealable skip for our suction vehicles to tip material into, or as a slave containment unit, which material is drawn directly into. When full these can be hydraulically sealed and removed from site.
