Pier UK Vacuum Excavation Truck

Vacuum Excavation is often seen as the safest method of excavation, as opposed to the more traditional methods of using picks, shovels, diggers etc.

The no-dig method provides a lower risk to workers on-site and helps to prevent utility strikes, which can often have long-lasting and severe consequences. A great example of this is a major project that took place in Bedford during August 2019 which also showcases how much quicker using a Vacuum Excavator can be, than using the more manual labour tools.

With new retaining walls needing to be built along the road, the customer knew that there were services across the site area, but were unsure where they were located. Initially, using 3 labourers over a 2-day period had resulted in only 1 out of 5 trenches being dug out in order to discover the location of the services and with 2 trenches needing to dug out per day; the time, spoil and cost to complete all 5 trenches was not going to work.

The depth of the trenches and spoil produced revealed that there were different levels of material that needed to be excavated thoroughly. With the use of our standard 26T machines, 2 operators used an air lance and a clay spade to make light work of the second trench. The job was successfully completed in 2 and a half hours which was a big improvement on the time taken. Using the PIER (UK) operators for the rest of the job meant that all 5 trenches were successfully excavated in a quick and safe manner, with the spoil contained inside the Vacuum Excavator, ready for backfilling.
