A simple and efficient means of rendering networks detectable is to add a localisation device
We propose two solutions:
Installation of a stainless steel wire and standard warning netting
A sleeved stainless steel wire is placed at the base of the trench and is used to transmit an electric signal produced with a surface-located generator along the entire length of the underground network.
It is then extremely easy to detect this signal and locate the network on a drawing with its depth using the appropriate appliance.
The stainless steel wire placed at the base of the trench is less susceptible to damage by site machinery and the network remains nevertheless detectable
In compliance with valid legislation, it is then sufficient to place a standard warning system over the top of the network.
Detectable warning systems
The warning facilities which have an incorporated stainless steel wire are placed over the pipes then connected together with a watertight connection to ensure continuity of the electrical current.
Our advises about detection in case of mechanized laying networks
On the big lengthes, we advise you to put a device standard detector over the network to be indicated, and to arrange the thread of detection in bottom of excavation (see for the detection of networks here).
