Another application of our unit is to assist in the location of buried underground utilities. The vacuum loading capability of our units, when used on conjunction with compressed air or pressurised water to loosen the ground, enables us to “dig“ for buried utility cables, without the risk of striking same with conventional excavators.
This system of excavation is frequently being employed by utility companies who are trying to locate buried cables or excavate bore holes or trial pits in contaminated sites, in the absence of utility maps. It is an extremely safe system of excavation as cables are not torn or broken by hydraulic excavation processes.
