Why is underground service locating important before digging?

Underground service locating gives you clearer information before excavation, helping you avoid costly strikes, delays and safety issues. Locator Guys identifies and marks detectable services such as power, water, gas, fibre, telecommunications, drainage and private services so your team can plan and dig with confidence.

What technologies do you use to locate underground services?

We use advanced methods such as Ground Penetrating Radar (GPR) and Electromagnetic Induction (EMI) to accurately detect a wide range of underground utilities, including non-metallic pipes. The right method depends on the service type, material, depth, access, ground conditions and whether a signal can be applied or detected.

How accurate and reliable is underground service locating?

While factors like soil conditions and pipe materials can influence detection, our industry leading technology combined with expert analysis consistently delivers precise, high confidence results you can trust. We are fully transparent about our findings and any limitations, empowering you to plan your project with complete clarity and confidence.

Are all underground utilities shown on utility maps?

No, maps can be outdated or incomplete. Professional on-site locating is essential to verify and accurately mark all underground services before excavation.

What should I do if I accidentally hit an underground utility?

Stop digging immediately and contact the relevant utility provider. Prompt reporting helps manage hazards and ensures safety compliance.

Schools, Sports Grounds & Event Sites

Fields, parks & temporary infrastructure

Locator Guys helps schools, sports grounds, stadiums, parks and event sites locate and map underground services before works, installations or temporary infrastructure are put in place.

These environments often include irrigation, drainage, power, lighting, communications, water lines and temporary event infrastructure. We help identify services before digging, pegging, trenching, marquee installation, fencing, repairs or upgrades.

Typical work includes:

Locating underground services beneath sports fields and school grounds
