Potholing using vacuum excavation, is a safe, efficient and accurate method used in exposing buried assets. Large industrial vacuums create high suction pressures and vacuum soil from the surface and below expose the buried assets i.e. water and gas. This method leaves a small diameter hole used to identify the buried asset. PVC inspection pipe and caps are then inserted to indicate where the assets are buried. These inspection pipes indicate the asset owner, pipe depth, material and size.
In tougher ground conditions, medium to high pressure water can be used via a lance and suction pipe to cut through clays and road bases. Our potholing lances are designed to use pressure and suction at the same time to reduce mess and provide safety to our workers. Although medium to high water pressure may sound damaging to services, it is pivotal in locating pipes and cables as it significantly reduces the use of other digging tools such as shovels and crow bars which could cause extensive damage.
