Vacuum Excavation works by providing a less stressful and safer alternative to traditional methods of excavators and spades.
Vacuum Excavation works in the following way:
- Move the remote-controlled boom over the area that requires excavation, around 6-8 inches above the ground material. Switch on the vacuum fans to start the suction process.
- As the material makes its way up the suction pipe, follow the material with the boom, ensuring the 6–8 inch gap is maintained to allow for constant air flow.
- As the service becomes visible, the material gets harder. The use of an air lance may be required to loosen the ground or clear the service.
- There is a selection of tools onboard to deal with different conditions. These include a reduced pipe size for narrow areas, an air lance for loosening material and air breakers for breaking up hard surfaces. All powered by a built-in compressor.
- The excavated material is stored in a built-in skip that is capable of holding 8m3. To reduce transport costs, we take the excavated material to a stockpile on site.
- The material is dispensed by lifting the lid upright and side tipping the material. The material can also be tipped directly into demountable skips, ready to remove from site and avoiding reloading.
- To prevent air contamination, the vacuum uses a 42-filter system that ensures that dust does not escape.
- With our vast experience in the Civil Engineering sector, we can offer advice on and other equipment or materials required to complete the task safely and can even assist with temporary works.
- To support projects, we can provide a full package, including ground protection with rubber mats or panels to fence off the work area.
Many contractors prefer the vacuum system when working in built-up areas as:
- it ensures safe excavation around existing services.
- it keeps footpaths clear of material to prevent slips, trips and falls for the work force and general public.
- the noise level of the equipment is under the legal requirement.
