When Subtera started out as MP Electrolocation over a quarter of a century ago, our business was a subset of Mosman Plumbing.

Today, our business has outgrown our origins, and we work with some of Western Australia’s biggest Environmental, Construction and Civil Engineering companies as well as Federal, State and Local Government clients, in the metro area and remote locations.

From our high quality ground penetrating radar, to concrete scanning and underground cable location, we carry out a wide variety of underground services across Perth and WA.


Our teams are available for fast deployment anywhere in the state for subsurface locating or concrete scanning work around Perth. Each team member has had extensive training and experience in subsurface locating. All our vehicles are identically equipped with a Mala Ground Penetrating Radar 500mMHz (Ideal for outdoors), Mala Ground Penetrating Radar CX 1.6GHz (Ideal for concrete scanning), Radiodetection 8000 line locators and Pit lifting aids.

Once on site, we can deliver results quickly – using high resolution images from nearmaps.com.au with all services marked and colour coded, tab markers, PVC markers or paint on the ground.


We are members of The National Utility Locating Contractors Association (NULCA) and are Telstra, Westnet and Perth Transport accredited.
