We are not plumbers that occasionally perform underground detection. Our Technicians are full-time, very experienced and highly focused in this specialized industry.

Acoustic Detection: Our experienced technicians use the latest acoustic leak detection equipment, listening for the noise created by water leaving the pipe. Once we are able to trace the trench line in which the water pipe has been laid, we listen directly above this line for the noise that is being created and usually successfully mark the exact location of your water leak. Depending on the size, depth and material of the water pipe and leak, this methods enables us to potentially detect the target leak very quickly.

Ferret Detection: Leak Detection Ltd is proud to be the first and possibly the only company in NZ to invest in this technology, which enables a “bullet” to be fed inside the pipeline and from the “bullet” position, determine which direction the water is leaking from and then accurately trace the line and leak position. This method can be great for leaks that are not able to be heard acoustically and gives us another tool to possibly help our clients.

Water Pipe Tracing: Our technicians are trained, experienced and the best in their field at applying Pipe & Cable Locating methods to help determine the underground pipeline positions, which are critical to aid the success of water leak detection. As we also specialise in the detection of all underground services (Sub Surface Detection Ltd.), we have multiple Pipe & Cable locating tools available through

Leak Solution Consulting: If your water pipeline needs to be replaced or added to, we can also help you through this process by identifying the pipe line entry points to buildings. Having years of underground civil contracting and experience, we work alongside many of Auckland’s directional drilling and underground civil engineering companies who are involved with water line maintenance and installations. It is our priority and goal to help the client solve their water leaking issue as economically as possible.

Ground Penetrating Radar (GPR): This equipment is used to aid picking up the position of underground services by pushing across the grounds surface and receiving images from below ground, it can be applied in circumstances when non-metallic pipelines such as plastics require detection. We currently have 4 x GPR units and very experienced technicians applying these daily on multiple projects, large and small.
