We use the most advanced leak detection equipment on the market

The SeCorrPhon AC 200 is one of our multifunctional leak detectors which combines three functions in one system: prelocation, pinpointing and correlation. This advanced machinery enables our team to confidently and quickly locate any leak, regardless of ambient conditions.

Once the pipeline data has been entered and the measurement begins, all other steps are performed with absolute accuracy.

D.U.D.S.’s commitment to using only the best technology will save you time and money when locating all types of problem water leaks.

Underground utilities

Down Under Detection Services has you covered

Water and Gas Leak Detection

Water pipe leak detection is undertaken using specialised Aquathon equipment, including the very latest SeCorrPhon AC 200. We also identify and locate gas leaks by using a flammable gas sniffer.

Electronic Pipe & Cable Location

Our electronic locating equipment is technologically advanced. It is capable of detecting water main and associated services, metallic gas services, Telstra cables and electrical services.

Ground Penetrating Radar (GPR)

GPR uses electromagnetic wave propagation to image and identify changes in electrical and magnetic properties in the ground. We can locate metal and non-metalic services to a depth of six metres.       

Concrete Penetrating Radar 

Concrete Penetrating Radar, (also known as Concrete X-Ray), is a form of non-destructive testing that records features and objects within concrete structures. Our service takes the risk out of the construction process.

Utility Mapping

Using specialised underground utility equipment, we identify the position of public utility mains. This includes lines for telecommunication, electricity distribution, natural gas and wastewater pipes.

Our vacuum pot-holing equipment is the safest method of excavation and identifying underground assets, their size number of services and depths. Fully restoring the site after the job is part of our service.
