Vacuum Excavation

The PIER (UK) team have created the below animated video and text to explain exactly how Vacuum Excavation works.

Some companies may not wish to use the traditional method of hand digging to reach underground utilities and so, that is where Vacuum Excavation comes in. As a more efficient method, using a Vacuum Excavator will ensure that safety is paramount.

How do the Vacuum Excavation vehicles work?

The operator will place the remote-controlled boom 6-8 inches over the selected area that requires excavation and the process will begin once the vacuum fans have been switched on. As the material starts to make its way up to the suction pipe, the operator will follow the material with the boom ensuring that the 6-8 inch gap is consistently maintained to allow constant air flow.

As the services becomes visible, the material will become harder and so, the use of an air lance may be required to loosen the ground or to clear the service. Within the vehicle, there are a selection of tools onboard to deal with an array of conditions i.e., reduced pipe size for narrow areas, an air lance for loosening material and air breakers for breaking up the hard surface – all of which are driven by a built-in compressor.

The material that the remote-controlled boom pulls up is stored in a built-in skip that is capable of holding 8m3 and in order to reduce the transport costs, our team will take the excavated material to a stoke pile on site to dispose of.

The material is dispensed of by lifting the lid upright and side tipping it to offload onto the ground. It can also be tipped directly into demountable skips, ready for removal from site to avoid reloading. To prevent any contamination with the air, the vacuum is created by air circulation with a 42-filter system to ensure that there is no escape of dust.

Why choose Vacuum Excavation?

Many contractors prefer the Vacuum Excavation system when working in a built-up area to ensure a safe excavation is completed around the existing series and to keep footpaths clear of material to prevent any injuries for both the on-site team as well as the general public. In addition, the noise level of the equipment used is under the legal requirement which means less noise for projects surrounding houses.

With our experience in the Civil Engineering industry, our team offer advice on other equipment or materials that may be required to complete the task in a safe and efficient manner and can also assist with the temporary works. In order to support the projects, we provide a full package of supply ground protection with rubber mats and fence panels to safely cordon-off the work area.
