Acoustic Leak Correlators
Twin-sensor units that measure the time difference between a leak's acoustic signature arriving at two known points along a pipe.
Used for: Underground water mains, slab leaks, supply lines under paving.
Equipment & Technology
The diagnosis is only as good as the equipment behind it. HydroTrace operates an inventory of detection, inspection, location and rehabilitation gear matched to the job — and the operator training to use it properly.
Browse By Capability
Leak Detection
Acoustic & Pressure-Based Detection
Pressurised water leaks make sound. The trick is hearing it through concrete, paving, soil and ambient noise.
Ground Microphones
High-sensitivity surface listening devices used to confirm correlator results and pinpoint the strongest acoustic point.
Used for: Final leak confirmation before excavation.
Tracer Gas Detectors
Safe hydrogen-nitrogen mix introduced into the pipe under pressure. The gas escapes through any leak and is detected at the surface.
Used for: Plastic pipes that don't transmit acoustic signals well.
Thermal Imaging Cameras
Infrared imaging detects temperature differences caused by hot-water leaks, water migration under slabs, or wet patches in walls and floors.
Used for: Hot-water slab leaks, wet-zone identification.
Pressure Test Pumps & Gauges
Calibrated test pumps with isolation manifolds for pressurising and monitoring individual pipe circuits.
Used for: Initial leak confirmation, line isolation, post-repair verification.
Pipe Inspection
CCTV & Internal Pipeline Imaging
Push-Rod CCTV Cameras
Flexible push-rod systems with self-levelling camera heads recording video and distance to defects.
Used for: Residential and small-bore drain inspection.
Crawler CCTV Systems
Motorised tractor units carrying steerable, pan-and-tilt camera heads for longer pipe runs and mainline sewers.
Used for: Commercial and municipal mainline inspection.
Digital Recording & Reporting Units
Inspection control units that record full video, capture stills of defects, measure distance, and generate reports.
Used for: Producing inspection records and post-repair verification.
Sonde Transmitters
Battery-powered radio transmitters built into camera heads. A locator finds the sonde's signal to mark position underground.
Used for: Marking defect locations on the ground above.
Utility Location
Cable, Pipe & Service Tracing
Electromagnetic Pipe & Cable Locators
Transmitter-receiver pairs that induce a signal onto conductive services and trace the signal route from the surface.
Used for: Water mains, sewer tracer wires, fibre conduits, telecoms, electrical reticulation.
Multi-Frequency Transmitters
Active signal injection at multiple frequencies to trace different service types under different ground conditions.
Used for: Complex sites with multiple buried services.
Sonde Locators
Surface receivers tuned to find radio signals from sondes inside CCTV camera heads or duct-mounted transmitters.
Used for: Marking specific defect locations during CCTV inspections.
Subsurface Imaging
Ground-Penetrating Radar & Concrete Scanning
Ground-Penetrating Radar (GPR)
Radar antennas towed across a surface emit pulses that reflect off subsurface features.
Used for: Locating non-conductive pipes, fibre conduits, voids, buried tanks, unknown services.
Concrete Scanners
High-frequency GPR units optimised for shallow scanning of slabs, walls and columns.
Used for: Pre-drilling, pre-coring and pre-cutting risk reduction.
GPR Data Processing Software
On-board and desktop software that turns raw radar data into interpretable plan views and target marking.
Used for: Producing marked site plans and survey reports.
Drain Cleaning
High-Pressure Jetting & Clearance
Trailer-Mounted Hydro Jetters
High-flow, high-pressure water jetting units rated for commercial and municipal drain cleaning.
Used for: Commercial sewer lines, restaurant grease lines, body corporate shared mains.
Specialised Jetting Nozzles
Application-specific nozzle sets — root cutters, grease-line scour nozzles, flusher heads, penetrator nozzles.
Used for: Matching clearance method to blockage type.
Drain Rods & Mechanical Augers
Manual and powered rodding equipment for initial blockage assessment and access creation.
Used for: Quick blockage probing, access for jetting.
Pipe Rehabilitation
Trenchless Repair & Relining
CIPP Liner Inversion Drums
Pressure vessels used to invert resin-impregnated liners into damaged pipes.
Used for: Trenchless rehabilitation of sewer and drainage lines.
Liner Curing Systems
Ambient-cure, hot-water, steam and UV-light curing options for setting CIPP liners in place.
Used for: Curing the liner to form a structurally sound pipe-within-a-pipe.
Packer & Spot-Repair Equipment
Inflatable packers used to install localised structural repairs on isolated pipe defects.
Used for: Single-defect repairs — displaced joints, localised cracks.
Brush Coating Rigs
Rotating brush systems that apply protective epoxy or polymer coatings to the inside of pressurised water mains.
Used for: Potable water, gas and process pipeline rehabilitation.
Testing & Measurement
Flow, Pressure & Network Diagnostics
Ultrasonic Flow Meters
Clamp-on, non-invasive flow measurement devices that record flow rates on live pipes without breaking into the line.
Used for: Water-loss audits, district metering, billing validation.
Data Loggers
Battery-powered loggers that record pressure, flow or noise data over extended periods.
Used for: Network monitoring, after-hours leak detection.
Noise Loggers
Compact acoustic loggers deployed at multiple points across a network.
Used for: District-scale leak detection, water-loss reduction programmes.
Reporting & Mapping Software
Digital reporting tools for producing inspection reports, marked-up site drawings, defect logs.
Used for: Every job — turning raw data into actionable findings.
