Newcastle Locating Services uses potholing, electronic detection and non-destructive digging for projects in Sydney, Maitland, Newcastle, Dungog and Singleton.

When it comes to working on the rail corridor, Newcastle Locating Services has RISI and Pegasus cards combined with years of industry knowledge and hands-on experience and a range of quality equipment to ensure the project goes smoothly. We've completed potholing of signalling cables and lines, electronic detection and surface marking within the rail corridor.

We've discovered that using a specific rail service technique with electronic cable and pipe locators can affect the operation of the signalling system. That’s why we've put together the following procedure for surface marking and cable location using ground penetrating radar, non-destructive digging, induction clamps, live connections, induction broadcasts and cables.


Induction Clamps

Induction clamps fit and clamp around the working cables. Once we've put them in place, we induce a locating signal into the cable or conductor(s). This sends a trace and gives you a clear idea of where the cables are. We use this when a direct connection isn't feasible.

Live Connection

Another means of electronic detection for projects in Hunter Valley, Singleton or Sydney is a live connection. This procedure allows you to connect to live conductors or cables. The live connector has its own isolating transformer to protect it, and it requires a minimum working rating of 440V.

Induction Broadcast

If you have unknown underground services that may lead to your worksite's target area in Port Stephens or Muswellbrook, you can use induction broadcast to locate them. It's not meant for precision locating as it only gives you the general vicinity of the underground services. A transmitter emits a signal into the ground. The ground penetrating radar picks up on any metallic entities in the induction zone and relays it to the receiver.


Potholing with cables can be difficult because there are many different types of cables. They're split into single or multiple conductor configurations, and they're individually insulated with an overall sheath to provide protection for underground installation. Fibre Optic cables contain no metal, and most cables are typically PVC insulated and sheathed.

Additionally, older cables have a copper tape barrier to combat vermin with a nylon jacket sheath, and you can have high or low voltage cables. All these things mean that you need a non-destructive digging expert like Newcastle Locating Services to assist you when performing an excavation.
