security for buried tubes
security for buried tubes
(OP)
Hi!
Did someone already hear to speak in the technical means, of a procedure of covering the tube, after some embankment centimeters, with a cheap mesh of expanded plastic?.
Its usefulness for example, to Protect the sought tube, of an accidental excavation, even when you know about its exact position, because you find the plastic first. This mesh, alert the operator of the machine of its proximity.
My interest, if you can help me, it is to know the technical term for its description, and it seeks of a maker, if exists.
