We are a well-established New Zealand owned and operated underground utility surveying company , providing a high quality service at a competitive price to commercial and residential clients across greater Auckland, Bay of Plenty, Waikato, Northland, and Coromandel.
We locate underground utilities and unknown objects to help you with the information you need prior to excavation and project planning. Our specialist technicians have decades of experience within the underground civil contracting field, where it is a priority to know the underground position of all network services prior to the commencement of any excavation.
We use the latest technology, including Ground Penetrating Radar (GPR) and Electromagnetic Induction (EMI) pipe and cable locating. This gives us the best chance to identify metallic and non-metallic underground services and objects such as, power, communications, gas, water, drainage, fuel tanks, manhole covers, steel reinforcements.
In addition to marking up underground utilities and services, we are able to provide high quality, to scale drawings, including GPS surveying for data collection of positions, Drone imagery, including depth indications to aid any project planning, delivered using AutoCAD in format types DWG and PDF.
Buried utilities and services are the veins and lifeblood of the community and any disruption through damage to power, water, gas or communications supply can severely impact homes and could paralyse businesses. Furthermore, it could cost thousands of dollars to reinstate supply. Any strike to a buried utility can also carry a serious health and safety risk too – hitting a buried power or gas line could potentially be disastrous and expensive to fix.

Sub Surface Detection has trained a total 12 Certified Locators, CURRENTLY 10 CERTIFIED LOCATORS within our team, to provide our clients with the reliable reactive service that the Civil and Construction Industries require.
