Ground Penetrating Radar (GPR)
GPR has the ability to detect both metallic and non-metallic pipes and cables. This allows for a comprehensive underground picture and reduces the risk of missing any unknown underground assets that may not have been marked when using traditional locating methods, especially when buried beneath hard stand areas such as concrete slabs.
Examples of detectable services using Ground Penetrating Radar technology include:
- PVC and Poly Water Pipes
- Underground Tanks
- Empty Ducts
- Buried Concrete Slabs
- Underground voids or disturbances and Underground Utilities (non-metallic services)
AJ Water can use the Ground Penetrating Radar as a standalone device or in conjunction with our conventional locating devices in order to meet our customers needs.
Concrete Slab Scans
AJ Water & Leak Detection use The Noggin 1000MHz GPR which is essential for shallow applications such as concrete inspection where resolution is critical. It has a centre frequency of 1000 MHz; this allows us to zone in on depths from 0 – 500mm. It can help with the location of rebar, post-tension cables and also depths of concrete slabs.
Pipe & Cable Locating Service
AJ Water & Leak Detection has over 10 years’ experience in pipe and cable locating. No matter how big or small your project is we can help. Pipes and cables can be broken through using machinery or even using a shovel; such breakages of pipes and cables can be expensive to repair. For a minimal fee we can locate all your services. Before conducting onsite cable locations, we will gain all relevant documentation and plans from Dial before you Dig (1100).
We service both residential and commercial customers as well as councils, civil contractors, builders, plumbers, electricians, landscapers and everyday householders.
The team at AJ Water consists of 7 qualified plant locators and we are NULCA Accredited. Infrastructure that can be located with the latest model locators are as follows:
- Aurora (Power)

CCTV Pipe Inspections & Surveys
AJ Water & Leak Detection have a wide range of CCTV pipe inspection cameras. Ranging from our smaller push units to our fully equipped main line CCTV vans. These are designed to operate in pipes ranging in diameter from 90mm to 1800mm. We are able to camera your sewer and stormwater lines to carry out pipe surveys for asset information and provide a condition rating, locate connections and pits, locate breaks, tree roots or anything else that could be blocking drains.
Our camera units are fitted with a Sonde on the back of the camera that enables us to locate the camera head above ground, which can pinpoint the location. This information can assist in locating alignment, depth, buried pits and manholes, blockages and breaks. We can also supply you with a formatted USB of the pipe surveyed. AJ Water are Wincan VX compliant and our staff are all well trained and accredited.
Got a water leak? AJ Water & Leak Detection boast state of the art acoustic leak detection equipment. Leaking water pipes can be very costly especially when they leak over a long period of time, not to mention the damage they can cause. Quite often water leaks can be occurring with no visual signs at ground level. Our equipment is used to isolate water pipes and listen for any leakage. The initial step will in most cases give an indication of where a water leak may be, and we then use highly sensitive ground microphones to search in the indicated area for the issue. The area of the leak can, in most cases be narrowed down, making repairs far more cost effective.
Pipe Patching & Repair
AJ Water & Leak Detection offers no dig internal pipe patching. The fibreglass pipe patching is very effective in hard to get to areas. Providing there is an inspection opening, pit or manhole accessible, the pipe patching equipment can be put into position. Using a CCTV camera and this equipment the pipe can be repaired without excavation or reinstatement thus saving time and considerable money. Pipes can be repaired from 90mm to 300mm in diameter.
Hydrostatic Excavation and High Pressure Drain Cleaning/Vac Truck
AJ Water & Leak Detection are proud to offer the service of 2 Hydrostatic Vacuum Excavation Trucks (non-destructive excavation). These have the capacity to carry either 3,000 litres or 4,500 litres of spoil. We specialise in the safe location and exposure of services through hydrostatic excavation (high pressure water and vacuum).
In conjunction with hydro excavation we also offer high pressure drain cleaning, pit and conduit cleaning and vacuum emptying of tanks.
AJ Water can provide a one stop shop, with the capabilities of underground pipe and cable locating of the asset then hydrostatic excavation to expose it.
Smoke & Dye Testing
Smoke testing is a method used to find stormwater infiltration into the sewerage system. The test consists of blowing non-hazardous smoke into sewer manholes and observing the points where the smoke emits. The smoke may exit from manholes, sewer vents on houses, down pipes or through the ground.
The smoke should not enter your house if it is plumbed to code as your toilet, sink and basin etc should have a water trap to prevent this.
Smoke testing is a simple and fast method of testing the sewer system. The vapour is harmless and will disappear after only a few minutes. In conjunction with dye testing this is a cost-effective way to identify areas of the sewer system that need repairs or improvement.
Water Flow Testing & Mains Pressure Testing
AJ Water & Leak Detection can carry out water flow testing on new infrastructure, new subdivisions or any developments where required. Using the latest equipment our tests are reliable and consistent, giving our water authorities, civil contractors, engineers and plumbers, quality testing and reporting on water mains, connections, hydrants and fire systems.
Backflow Prevention and Temperature Control Valves
AJ Water & Leak Detection are qualified to install, test, and maintain back flow prevention devices in accordance with Australian Standards. Back flow prevention devices are designed to protect the potable water supply, so that if a cross connection exists and a backflow incidence does occur any contamination is prevented. Hand in hand with Backflow Prevention are Temperature Control Valves. These are prevalent in schools, day care centres, hospitals and nursing homes. AJ Water are licenced to carry out testing, maintenance, fitting and replacement of these units.
AJ Water carry out maintenance testing on all of these devices in accordance with the Australian Standard 3500.
