Water-tightness Testing of Water Storing Concrete Structures / Use of Tracer Dye Colour

Water-tightness Testing of Water Storing Concrete Structures / Use of Tracer Dye Colour

Fluorescent or UV detectable, i.e. Natrium Fluorescein or similar biodegradable, non-ionic dye tracer, can indicate potential leakage location much easier, in cases of reservoir’s base slab leakage – it can be detected easily in drainage system, removable by Chlorine (disinfection of drinking water reservoirs prior of placement into operation is anyway mandatory).
