Before excavation, coring, cutting or leak repairs begin, concealed services need careful consideration. Underground utility locating services can help identify the likely path of cables, conduits and pipework around commercial and industrial sites, helping project teams plan work with better site information.

Digging, trenching, coring, saw cutting and slab penetration can all bring work crews close to services that are not visible from the surface. Cable and conduit location supports commercial and industrial plumbing work by helping identify underground or concealed assets before repair, excavation or construction activity begins.
This is often relevant when a suspected leak route needs investigation, a service main may run through an excavation area, or a project requires work through concrete, bitumen, soil or landscaped ground. Existing drawings and plans are useful starting points, but they may be incomplete, old or inaccurate. Onsite investigation can provide further information for planning the work.
What may need to be located
Cable and conduit location may relate to a range of assets within a commercial, industrial, strata or facility-managed site. Depending on the site and task, this can include water mains, gas services, electrical conduits, communications conduits, stormwater pipes, sewer lines, irrigation mains, fire services and trade waste lines.
It may also assist with understanding the route of a pipe before leak repairs, marking services before excavation, or scanning a slab before coring or cutting. The purpose is not simply to find a line on the ground; it is to give the people planning the work a clearer picture of what may sit within or below the proposed work area.
When cable and conduit location may be useful
Before excavation or trenching near known or suspected services.
Before drilling, coring, saw cutting or penetrating a concrete slab.
When planning leak repairs that may require digging or opening up surfaces.
When a pipe route needs to be investigated before further work proceeds.
When available plans need onsite consideration alongside the physical site.
When a project area contains a mix of buried or embedded infrastructure.
In leak detection work, cable and conduit location can form part of the broader process of narrowing down where a concealed fault or service route may be. Other leak detection approaches listed by Find a Master Plumber include acoustic testing, data logging, correlators, hydrogen gas detection testing and pipe microphone work.
How locating methods can support site planning
Different conditions can call for different approaches. Electromagnetic cable and pipe locators, signal transmitters and sondes may assist with conductive services or services able to carry a signal. Ground Penetrating Radar (GPR) uses radar signals to help identify subsurface features, which may include pipes, cables, conduits, voids, tanks, slabs, reinforcement and other underground objects.
Mark-out paint, survey equipment and service mapping tools may also be used to communicate findings around a work area. Results can be affected by factors such as soil type, depth, moisture, reinforcement, congestion and site conditions. This makes clear site information and practical access arrangements valuable before an investigation is planned.
Prepare useful information before you enquire
Commercial and industrial sites often have access, operational and approval considerations that affect how work is planned. Providing relevant information at the outset can help a plumbing business understand the proposed task and site environment.
Define the work area: identify the excavation, trench, slab, repair area or suspected pipe route.
Gather available records: include Before You Dig plans, site drawings and any relevant asset information.
Describe the surface: note whether the area is concrete, bitumen, soil or landscaped.
Share visual details: photos of pits, meters and the surrounding area can provide useful context.
Flag site requirements: advise of access restrictions, traffic or pedestrian controls, inductions, shutdown windows and the person authorised to approve work.
Explain the planned activity: state whether the work involves digging, trenching, coring, saw cutting or another form of penetration.
For industrial operations, it may also be relevant to identify isolation requirements, safety permits, process impacts, environmental controls, confined-space risks, hot works requirements and critical production impacts.
Equipment and supply names you may encounter
Customers may encounter a range of equipment and supply-channel names while discussing cable and conduit location. Examples include Radiodetection, Vivax-Metrotech, Leica, GSSI, Mala, Hilti, Trimble and Topcon. Reece, Galvins, Tradelink, Parkwood Plumbing Centre, Bunnings and Plumbing Plus are also among associated supply-channel names.
These examples indicate the range of brands and channels connected with locating equipment, surveying, scanning, tools and plumbing supplies. They are not endorsements, and their mention does not indicate that every plumbing business uses, supplies or services a particular product.
Choose a plumbing business with the right conversation in mind
For a facility, business or industrial site, the most useful enquiry explains both the location task and the operational setting. Include the asset or area involved, site access details, relevant plans, the work proposed nearby and any restrictions that could affect timing or access.
Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
Cable and conduit location relates to identifying underground or concealed services before work such as excavation, drilling, cutting, trenching, leak repair or construction activity. It can assist with finding the likely route of pipes, cables and conduits around a work area.
Why are site plans not always enough?
Drawings and service plans may be incomplete, old or inaccurate. They can be useful information to provide, while onsite verification can help build a clearer understanding of the work area.
Can locating assist before concrete cutting or coring?
Yes. Concrete slab scanning before coring or cutting is one application described for service locating. GPR may help identify subsurface features such as pipes, cables, conduits, slabs or reinforcement.
What information should I provide for an underground cable locating service?
Provide available Before You Dig plans and site drawings, the suspected route or work area, photos of pits or meters, the required depth, service type, surface material and access restrictions. Also explain whether digging, trenching, coring, saw cutting or slab penetration is planned.
What can affect locating results?
Results may be affected by soil type, depth, moisture, reinforcement, congestion and site conditions. Electromagnetic locating is generally suited to conductive services or services that can carry a signal, while GPR can assist in other circumstances or where a broader subsurface scan is needed.
How does service locating relate to leak detection?
Service locating may help identify pipe routes and support planning before excavation or repairs. Within commercial leak detection, it can be used alongside other investigation methods to narrow the location of concealed pipework or a suspected fault.
