Vacuum Excavation

Vacuum excavation is an intrinsically safe method of avoiding dangerous and expensive utility strikes. In line with HSG47 industry best practice, the method eliminates the threat from buried services, whether it be checking for known services or for excavation at borehole positions prior to drilling.

Depending on the ground conditions the excavation methods are either by: Hydro Vacuum Techniques: uses a high pressure water jet delivered by a cyclonic “nozzle”; can be used in all soil types including cohesive soils; and slurry waste is removed into the on board storage tank by suction methods and then safely disposed of. or by Pneumatic Methods: which injects air into the ground, loosening the materials, which are then removed by suction methods; is suitable for non-cohesive soils; and produces dry spoil which can easily be placed back into the ground.

Both methods have the capacity for concrete coring and capability to break out with a pneumatic hammer prior to vacuum excavation. Extensions can be made up to 20m away from the main excavation plant for areas where there is restricted access. Our fully trained and competent crews are highly experienced in working in many sectors including National Grid, Highways, Rail and Petrol Forecourts. The crews hold the appropriate competence training for working in these sectors including: CSCS, HSG47, SPA, National Grid BESC, National Grid Competent Person, NRSWA Streetworks.
