INSTRUMENTAL LINE-TRACING, DETECTION OF BURIED ACCESSORIES
It is often the case that network operators do not have a reliable register of the state of the network, and that - e.g. after road construction - some of the valve-boxes "disappear" because they have been buried by land-fills or covered by road-pavement.
Our modern line-tracing and detection instruments make it possible for us to check the field, to trace the routing of metallic and also non-metallic (!) pipelines, to determine the depth at which pipelines were laid and to detect buried valve-boxes.
