UV COLOR Yellow : when invisible leaks become visible in seconds
Every day, countless leak repairs are done in the wrong place. The truth is simple: water never takes the path you expect. It creeps along cables, travels upward through porous joints, seeps across insulation layers, and reappears metres away from the entry point. A skilled technician knows that locating a leak requires more than the naked eye.
That’s where UV COLOR Yellow makes all the difference. This professional-grade fluorescent dye allows you to trace the exact path of water with surgical precision, revealing a bright yellow fluorescent signature under UV light. More than just a product, it’s a strategic diagnostic tool — transforming inspections, shortening intervention times, and eliminating unnecessary repairs.
Why fluorescent leak tracing is essential for accurate diagnostics
Water : an unpredictable adversary
Anyone who’s ever tracked a leak knows that the damp spot is rarely where the leak actually starts. Water can:
- bypass invisible obstacles
- travel several metres unnoticed
- infiltrate through porous materials as if they were hidden highways
This explains why nearly 80% of diagnostic errors stem from approximate localisation.
The limits of traditional detection methods
- Visual inspection: helpful but misleading when the visible moisture is far from the source.
- Smoke tests: effective for air leaks but useless for tracing water.
- Thermal cameras: excellent for moisture detection but unable to show the exact path of infiltration.
That’s where UV COLOR Yellow bridges the gap — it clearly shows the water’s real course through any structure or waterproofing system.
How UV COLOR yellow works – science meets field expertise
The fluorescence principle
Fluorescence is a simple physical reaction: certain molecules absorb ultraviolet (invisible) light and re-emit it as visible light — in this case, a bright, intense yellow. What makes UV COLOR Yellow so powerful is :
- Exceptional brightness: even a thin film of water remains clearly visible.
- Optimal contrast: easy to identify, even in complex environments.
- Instant revelation: the leak path becomes visible in real time.
A formula designed for real-world conditions
UV COLOR Yellow has been engineered for field use:
- Uniform diffusion: ensures even colour distribution, no patches or fading.
- Universal compatibility: works with drinking water, wastewater, and industrial circuits.
- Material neutrality: safe for all surfaces and coatings.
- Easy rinse: cleans up completely with clear water — no residue or staining.
Key applications of UV COLOR yellow
Roofs and terraces – tracking elusive leaks
On flat roofs, water can travel under membranes, around obstacles, through insulation layers, and emerge far from the actual defect. Typical scenario: moisture appears in a ceiling, but the entry point is at the other end of the roof. Fluotracking method:
- Dilute at 1.5% in clean water.
- Apply directly to suspected areas or upstream of the rainwater system.
- Inspect from below using a 365 nm UV lamp to visualise infiltration routes.
Sewerage networks – follow the leak to the last joint
In underground networks, every metre counts. A micro-leak can seep into soil or groundwater. Example: a lift station receives unexpected flow — the issue is upstream but invisible. Solution: inject UV COLOR Yellow at 2%, inspect at manholes and outlets under UV light, and pinpoint the leakage zone with precision.
Pools, basins, and fountains – ensuring waterproof integrity
Even a 2 mm loss per day can represent hundreds of litres. Method: add UV COLOR Yellow to the basin water, then inspect visually and under UV with a mask or underwater camera to locate fissures or seal failures.
Industrial maintenance – avoiding costly shutdowns
A small leak in a cooling circuit or hydraulic system can halt an entire production line. Use: add the dye to the process fluid and inspect under UV light for rapid, targeted identification of leaks.
Environmental and civil engineering – tracing natural water flow
Understanding how water moves through the ground is vital for hydrology and urban planning.
Applications:
- Soil permeability testing
- Tracking infiltration in wetlands
- Detecting contamination or pollutant migration
How to use UV COLOR yellow – Fluotracking’s recommended method
- Preparation Adjust the dilution according to your situation :
- Short range inspection: 1%
- Long distance / strong lighting: up to 3% Always use clean water to maintain fluorescence quality.
- Application Apply by spraying, injection, or direct incorporation depending on the system.
- Observation Use a 365 nm UV lamp. Move slowly and methodically to detect the first fluorescent traces.
- Documentation Photograph the fluorescent areas for reporting and traceability.
- Cleaning Rinse with clear water. The dye leaves no residue and does not alter materials.
