Numerous manufacturers are developing innovative devices to prevent damage that can occur to lines during civil engineering work. One such means is Trace Safe®, currently the only system for water-blocking locating wires. The heart of this innovation is a high tensile strength locatable wire with water-blocking threads. Because of simple connecting plugs, it is not necessary to remove the high-density polyethylene (HDPE) outer jacket of the locating wire. The advantages of Trace Safe lie in its strength; ease of use; lightning protection; and abrasion, compression, impact, and corrosion resistance.
