UV COLOR blue – reveal the invisible, detect leaks in seconds
A brand-new flat roof, signed off just two months ago. After one heavy night of rain, fine droplets appear on the ceiling of the top floor. No visible damp patches, no cracks in sight. For the property owner, it’s a nightmare. For the technician on-site, it’s a challenge. This is exactly where UV COLOR Blue becomes indispensable — a professional-grade fluorescent dye activated by UV light that shows you, quite literally, the path of the water. In under ten seconds, you can see where the leak starts, how it spreads, and where it exits.
Result:
- Less time wasted on inspection
- Fewer destructive interventions
- A client reassured on the very first visit
Why accurate UV tracing is the key to a reliable diagnosis
On-site, finding the true source of a leak is like chasing a draught in an old house – what you see isn’t always what’s really happening. Through capillarity, water can climb a wall, slip behind insulation, sneak through a 2 mm gap, and reappear metres away.
If you rely only on visible dampness, you risk repairing the wrong spot – and coming back later. According to Fluotracking’s field experience, 80% of leak misdiagnoses come from incomplete or absent tracing. Too often, we see repairs made to a joint or membrane section, only for the leak to persist – because the symptom was treated, not the cause.
That’s why UV COLOR Blue is essential :
- It tracks water through its real path, not just the visible effects.
- It provides visual proof you can show clients or include in reports.
- It drastically reduces search time – saving money and ensuring credibility.
How UV COLOR blue works – the science of fluorescent tracing
The principle behind UV COLOR Blue is simple yet incredibly effective. It is a fluorescent tracing dye, invisible to the naked eye when diluted in water, but glowing with intense electric blue under UV light (ideally at 365 nm).
The role of fluorescence
Fluorescence is the ability of certain molecules to absorb invisible ultraviolet light and re-emit it as visible light. In this case, UV COLOR Blue shines bright blue, creating immediate contrast even in difficult environments – low light, complex structures, or dark surfaces.
Homogeneous diffusion for reliable results
UV COLOR Blue has been formulated to blend perfectly with water and diffuse evenly, without heavy or light spots. That means even a 1 cm microfissure will glow clearly under UV, provided the dilution is done correctly.
Professional applications of UV COLOR Blue
What makes this tool exceptional is its versatility. At Fluotracking, it is used across four main sectors:
Roofs and terraces – Tracking hidden infiltrations
On flat roofs or terraces, water can travel under membranes, around insulation, or through layers before resurfacing. With UV COLOR Blue, you can simulate controlled rain and watch exactly how water moves.
Drainage and sanitation networks – Following the flow to the last joint
In sewer or stormwater networks, leaks can be difficult to pinpoint – especially in buried or extended systems. Inject UV COLOR Blue into the system and inspect potential outlets under UV light to reveal the leak’s path instantly.
Industrial use – High-precision leak tracing
In industrial environments, even a minor leak in a hydraulic or cooling circuit can stop production. UV COLOR Blue detects the smallest cracks or seepages immediately under UV inspection, even in complex piping systems.
Environmental and urban engineering – Water flow analysis
For hydrology, civil engineering, or land planning, UV COLOR Blue helps visualise water circulation over long distances, identifying drainage patterns or stagnation zones.
How to use UV COLOR blue effectively
Many users simply dilute and apply – but for optimal diagnostic performance, Fluotracking recommends this method :
1. Prepare the dilution
- Short-distance inspection: 1% solution
- Long-distance or high-light conditions: up to 3% Always use clean water to preserve fluorescence quality.
2. Apply smartly Start upstream of the suspected area and allow time for the water to circulate.
3. Inspect methodically Move the UV lamp slowly and record the exact fluorescence points. Take photos for documentation.
4. Clean after use Rinse with clear water. No chemicals needed. No residue left.
